LUVERNE Grip Step wheel-to-wheel running boards equip your pickup truck for whatever job lies ahead. They offer easier truck bed access, fleet-level safety, a highly rust-free construction and a custom fit for your truck and lifestyle. Grip Step wheel-to-wheel steps are the ideal solution for better truck bed access. Whether you need to reach a truck tool box, ladder rack or some cargo in the truck bed, the wheel-to-wheel steps are extra-long, providing a convenient step up for reaching into the truck bed. Grip Step running boards are also built for hard work, featuring expanded metal treads that offer fleet-approved safety. The open treads ensure maximum traction for your boots -- whether rain or shine -- and they also help keep your truck's interior clean by allowing dirt, snow and debris to pass through the boards. For superior resistance to the elements, Grip Step wheel-to-wheel running boards are made from aluminum alloy. They're strong, lightweight and highly corrosion-resistant. To maximize this corrosion resistance, the running boards and brackets are both shielded in a durable black powder coat finish. The running boards also feature hardened plastic end caps that eliminate sharp corners and add a professional touch. All LUVERNE Grip Step wheel-to-wheel steps are designed for vehicle-specific applications. This ensures a custom fit and the easiest possible installation. The running boards mount with vehicle-specific brackets and use pre-existing mounting points to avoid difficult modifications. This particular set of wheel-to-wheel running boards is designed to fit specific years of the Chevy Silverado 2500 HD or 3500 HD and GMC Sierra 2500 HD or 3500 HD (see application information to verify fitment; brackets included but shipped separately).
Grip Step wheel-to-wheel running boards are designed to be the best running boards for work trucks, featuring a unique expanded metal tread pattern for superior traction and a 7" width for reliable footing.
LUVERNE has manufactured truck accessories in the United States since 1963, specialising in grille guards, running boards, side steps and mud guards for pickups, commercial vans and SUVs. Products are built primarily from stainless steel, aluminium and mild steel, with model-specific mounting kits that use existing frame locations for a bolt-on installation.
LUVERNE has been manufacturing automotive accessories in the United States since 1963, and six decades of continuous production have made it a nationally recognised name in the truck accessory market. Now a Lippert brand, it concentrates on a defined set of products rather than spreading across the whole aftermarket: front-end protection, step access and spray protection for pickup trucks, commercial vans and sport utility vehicles.
Step products are the largest part of the catalog and the range is unusually deep, because the right step depends on the vehicle's ride height, the width of the rocker panel and how often people get in and out. The O-Mega II six-inch oval steps give a wide, flat standing surface in polished stainless or black powder coat, while the Regal 7 seven-inch oval steps go wider still for full-size crew cabs and lifted trucks. The broader running board and side bar range covers round tube, oval and boxed profiles across cab configurations, with treads positioned at the door openings where they are used.
Grille guards protect the front end against impacts, brush and road debris, built in tubular stainless or steel with model-specific brackets that tie into factory frame mounting points. Because the fit is engineered per vehicle, installation is a bolt-on job that does not require drilling or cutting on most applications.
Rounding out the line, LUVERNE mud guards and mud flaps shield rocker panels, paint and following vehicles from stones and road spray, in widths matched to the tyre and fender they sit behind. Material choice runs through everything the brand does: stainless steel where appearance and corrosion resistance matter most, aluminium where weight is the priority, and mild steel with protective coating where strength and value lead. Customers include contractors, fleet operators, van upfitters and truck owners.

The Model 415114 Grip Step is a universal step board assembly designed to fit many vehicle applications. It consists of an aluminum extrusion step board (part 551388, 113.62 inches long) that can be cut to custom lengths, support braces, end caps, and mounting hardware. The step board is black and can be modified to fit various vehicle types by cutting to the required length.
The Model 400717 Wheel to Wheel Step Bracket is specifically designed for 2007 GM Silverado and Sierra pickups in Regular, Extended, and Crew Cab configurations. If your vehicle is a different year, make, model, or cab style, this bracket will not fit. You will need to verify your vehicle matches these specifications before purchasing.
Yes. The Model 415114 Grip Step board assembly is designed to work with the Model 400717 bracket package. The step assembly attaches to the mounting brackets using carriage bolts, washers, and flange nuts. Follow the installation instructions in both the step assembly package and the bracket package for proper assembly.
You will need a cutting tool to modify the step board length: a saber saw, chop saw, or hack saw. You will also need flat black paint to touch up the cut ends. For assembly, you will need a wrench or socket set to tighten the supplied fasteners (carriage bolts, washers, and flange nuts) to the specified torque of 19 LB FT.
You will need a wrench or socket set to hand-tighten and then torque fasteners. A torque wrench is required to tighten fasteners to 19 LB FT. You may need a tool to loosen the spring hanger bolt slightly (step 3.1) to slide the inboard spring hanger mounting bracket behind the bolt flange. Standard hand tools for bolt installation are required.
The manual does not specify whether battery disconnection is required. Contact the manufacturer or a qualified installer for guidance on this step.
The Model 415114 step package includes: 2 aluminum extrusion step boards (part 551388, 113.62 inches long), 10 upper support braces (part 551296), 4 end caps (part 551394), 14 lower spacer plates (part 551298), 20 carriage bolts 5/16-18 x 1.0 inch (part 108683), 20 flat washers (part 101369), 20 serrated flange nuts (part 102680), and 8 self-drilling tek screws #8 x 1/2 inch (part 107958). Note: some flange nuts may be supplied in the bracket package instead.
The Model 400717 bracket package includes: 6 mounting brackets (part 551863), 6 nylon spacer washers (part 107182), 12 M8 x 30 x 1.25 screws (part 100180), 12 flat washers (part 106998), 6 5/16 x 1.00 inch screws (part 100647), 6 M8 flanged nuts (part 105859), 6 U-nuts 5/16-18 (part 105541), 6 pinch weld support brackets (part 551666), 4 1/2 inch flat washers (part 100118), 2 nylock hex nuts 3/8-16 (part 102381), 2 hex head bolts 3/8-16 x 2.00 inch (part 101326), 4 3/8 inch flat washers (part 100062), 2 outboard spring hanger mounting brackets (part 551892), and 2 inboard spring hanger mounting brackets (part 551806).
Determine the required length for your application. Cut the aluminum extrusion step board (part 551388) to that length using a saber saw, chop saw, or hack saw. After cutting, use flat black paint to touch up the cut ends to prevent corrosion and maintain appearance.
1. Cut the step board to the required length and paint the cut ends black. 2. Slide the appropriate number of support braces (part 551296) into the channel of the step board (part 551388). 3. Slide the end caps (part 551394) over the front and rear of the step. 4. Screw the end caps to the bottom of the step using the supplied #8 x 1/2 inch self-drilling tek screws (part 107958). 5. Set the step on the mounting brackets and slide each support brace over the top of each mounting bracket. 6. Attach the flat spacer plate (part 551298) to the bottom of the step between the support brace and the top of the mounting bracket. 7. Attach using the 5/16-18 x 1 inch carriage bolts, washers, and flange nuts (parts 108683, 101369, 102680). 8. Tighten all fasteners to 19 LB FT.
1. Check if your vehicle has threaded inserts in the rocker panels. If not, insert 5/16 inch multi-thread U-nuts (part 105541) into the upper holes in the rocker panel. 2. If the vehicle does not have threaded inserts, attach the top of the mounting brackets (part 551863) using 5/16-18 x 1.0 inch screws and flat washers (parts 100647 and 106998), hand-tightened only. If the vehicle has threaded inserts, use black M8 x 30 mm screws (part 100180) instead. 3. Insert a nylon washer (part 107182) between the top of the mounting bracket and the bottom of the rocker panel. 4. Install the black M8-1.25 screw (part 100180) and washer (part 106998). 5. Place the pinch weld support bracket (part 551666) above the pinch weld. 6. Install the M8 flange nut (part 105859). 7. Tighten all fasteners to 19 LB FT.
1. Loosen the spring hanger bolt just enough to slide the inboard spring hanger mounting bracket (part 551806) up behind the flange of the bolt. Position it with the channel open to the outboard side. 2. Install the outboard spring hanger mounting bracket (part 551892) so its inboard vertical portion fits inside the channel of the inboard bracket. 3. Use the 3/8 inch zinc-plated bolt (part 101326), 3/8 inch washer (part 100062), 1/2 inch washer (part 100118), and 3/8 inch zinc-plated nylock nut (part 102381) to connect the brackets. 4. Do not tighten these bolts until the bracket is attached to the step assembly. 5. After the step assembly is attached, tighten the spring hanger bolt per the manufacturer's specifications.
All fasteners on the Model 415114 Grip Step assembly must be torqued to 19 LB FT. This includes the carriage bolts (part 108683) that attach the step to the mounting brackets, and the self-drilling tek screws (part 107958) that attach the end caps.
All fasteners on the Model 400717 bracket must be torqued to 19 LB FT. This includes the rocker panel fasteners (5/16-18 x 1.0 inch screws or M8 x 30 mm screws depending on whether the vehicle has threaded inserts), the M8 flange nuts, and the pinch weld support bracket fasteners. After the step assembly is attached, tighten the spring hanger bolt per the manufacturer's specifications (not specified in this manual).
The carriage bolts are 5/16-18 x 1.0 inch stainless steel (part 108683). They are used with flat washers (part 101369) and serrated flange nuts (part 102680), also stainless steel. All fasteners must be torqued to 19 LB FT.
If your 2007 GM Silverado or Sierra does not have threaded inserts in the rocker panels, use 5/16-18 x 1.0 inch zinc-plated screws (part 100647) with flat washers (part 106998). If your vehicle has threaded inserts, use black M8 x 30 x 1.25 inch stainless steel screws (part 100180) instead. All rocker panel fasteners must be hand-tightened first, then torqued to 19 LB FT.
The spring hanger mounting brackets are connected using 3/8-16 x 2.00 inch zinc-plated hex head bolts (part 101326) with 3/8 inch flat washers (part 100062), 1/2 inch flat washers (part 100118), and 3/8-16 zinc-plated nylock nuts (part 102381). These bolts must not be tightened until the bracket is attached to the step assembly. After the step assembly is attached, tighten the spring hanger bolt per the manufacturer's specifications.
The U-nuts are 5/16-18 (part 105541). They are inserted into the upper holes in the rocker panel. Note: some vehicles have threaded inserts in the rocker panels and will not require U-nut installation.
Yes. When attaching the top of the mounting brackets to the rocker panel, hand-tighten the 5/16-18 x 1.0 inch screws and flat washers first. After all fasteners are in place and the step assembly is attached, tighten all fasteners to 19 LB FT using a torque wrench.
Do not tighten the spring hanger bolts until the bracket is attached to the step assembly. After the step assembly is fully attached, tighten the spring hanger bolt per the manufacturer's specifications. The manual does not provide the specific torque value for the spring hanger bolt.
The nylon washer (part 107182, 0.312 inch ID x 1.24 inch OD x 0.25 inch thick) is inserted between the top of the mounting bracket and the bottom of the rocker panel. It provides spacing and protection between the bracket and the vehicle's rocker panel.
The pinch weld support bracket (part 551666) is placed above the pinch weld during installation of the Model 400717 bracket. It provides structural support at the pinch weld location on the vehicle's rocker panel.
The manual states to slide the appropriate number of support braces (part 551296) into the channel of the step board. The service parts list includes 10 support braces per step package, but the exact number required depends on your specific application and the length of the step board after cutting. Consult the bracket package instructions for the specific number needed for your vehicle.
The service parts list includes 4 end caps (part 551394) per step package. These are slid over the front and rear of each step board and secured with self-drilling tek screws.
The end caps (part 551394) are attached to the bottom of the step using the supplied #8 x 1/2 inch self-drilling tek screws (part 107958). These are stainless steel with black coating. The manual does not specify a torque value for these screws.
The flat spacer plate (part 551298) is attached to the bottom of the step, between the support brace and the top of the mounting bracket. It provides spacing and distributes the load between the step assembly and the mounting bracket.
The manual does not address reuse of factory fasteners. All fasteners required for the Model 415114 Grip Step assembly are supplied in the step package and bracket package. Use only the supplied fasteners as specified in the service parts list.
The manual does not describe any permanent vehicle modifications required for the Model 400717 bracket installation. However, you must loosen the spring hanger bolt to slide the inboard spring hanger mounting bracket behind its flange. The installation uses existing holes in the rocker panel and spring hanger area.
After installation, verify that all fasteners are tightened to 19 LB FT. Ensure the step is positioned correctly and securely attached to the mounting brackets. Check that the end caps are properly secured and that there are no gaps between the step board and the brackets.
After installation, verify that all rocker panel fasteners are torqued to 19 LB FT. Ensure the spring hanger bolt is tightened per the manufacturer's specifications. Check that the mounting brackets are securely attached to the vehicle and that the step assembly is properly positioned. Verify that all fasteners are tight and there are no gaps between the brackets and the vehicle.
The Model 400717 bracket is designed only for 2007 GM Silverado and Sierra pickups in Regular, Extended, and Crew Cab configurations. If your vehicle is a different year, make, model, or cab style, this bracket will not fit.
You will need a saber saw, chop saw, or hack saw to cut the step board to length, plus flat black paint to touch up the cut ends.
Yes. The step board can be modified from its original length to fit many applications. Cut it to the required length using a saber saw, chop saw, or hack saw, then touch up the cut ends with flat black paint.
All fasteners on both the Model 415114 Grip Step and Model 400717 bracket must be torqued to 19 LB FT. The spring hanger bolt on the Model 400717 should be tightened per the manufacturer's specifications after the step assembly is attached.
Yes. When installing the Model 400717 bracket, hand-tighten the rocker panel fasteners first, then torque all fasteners to 19 LB FT after the step assembly is in place.
Do not tighten the spring hanger bolts until the step assembly is attached to the bracket. After the step assembly is fully attached, tighten the spring hanger bolt per the manufacturer's specifications.
Yes. The Model 415114 step assembly instructions state to follow the instructions included with the specific bracket package to mount the brackets to your vehicle. Both the step assembly and bracket package instructions must be followed.
Yes. Some vehicles have threaded inserts in the rocker panels, which affects fastener selection. If your vehicle has threaded inserts, use M8 x 30 mm screws (part 100180). If not, use 5/16-18 x 1.0 inch screws (part 100647) with U-nuts (part 105541).
If your vehicle has threaded inserts in the rocker panels, you will not need to install U-nuts (part 105541). Instead, use black M8 x 30 mm screws (part 100180) in place of the 5/16-18 x 1.0 inch screws (part 100647). These screws will thread directly into the threaded inserts. All fasteners must still be torqued to 19 LB FT.
The Model 415114 step board can be cut to a shorter length using a saber saw, chop saw, or hack saw. After cutting, use flat black paint to touch up the cut ends to prevent corrosion and maintain the appearance of the step.
The spring hanger bolt must be loosened just enough to slide the inboard spring hanger mounting bracket (part 551806) behind the flange of the bolt. If the bolt is stuck, apply penetrating oil and allow it to soak. Use appropriate tools to carefully loosen the bolt without stripping it. Do not force the bolt.
If any fasteners become loose after installation, retighten them to 19 LB FT using a torque wrench. Check all fasteners periodically, especially after the first few uses of the step, to ensure they remain tight.
