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 Ram 3500 (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 for pickup trucks and other vehicles. It consists of an aluminum extrusion step (item #1, part number 551388), support braces, end caps, spacer plates, and fasteners. The step can be cut to custom lengths to fit various vehicle applications.
The Model 415114 Grip Step is designed for universal applications. However, the step board itself is application-agnostic; fitment depends on the specific bracket package used. You must follow the instructions included with your vehicle-specific bracket package to mount the brackets to your vehicle.
Yes, the Model 571339/401339 W2W Mega/Grip Step Bracket is designed specifically for 2013-2015 RAM 3500 Pickups in all cab styles: Regular Cab, Quad Cab, Crew Cab, and Mega Cab. However, the rear bracket orientation differs between Regular/Quad/Crew Cab and Mega Cab models, so you must refer to the appropriate figure (Figure 1 for Regular/Quad/Crew Cab, Figure 2 for Mega Cab) during installation.
No. For Regular Cab pickups, only the front and rear cab mounting brackets are used. The center mounting bracket and its fasteners may be discarded and are not needed for installation.
To cut the step board to length, you will need a saber saw, chop saw, or hack saw. You will also need flat black paint to touch up the cut ends. Standard hand tools for fastening (wrench or socket set for 5/16-18 fasteners) are required but not explicitly listed.
The Model 415114 Grip Step includes: 20 carriage bolts (5/16-18 x 1", part number 108683), 20 flat washers 5/16" (part number 101369), 20 serrated flange nuts 5/16-18 (part number 102680), and 8 self-drilling tek screws #8 x 1/2" (part number 107958). Some flange nuts for the 5/16-18 fasteners may be supplied in the specific bracket package instead of the step package.
The bracket package includes: 4 M12-110mm hex head screws (part number 103444), 2 M12-160mm hex head screws (part number 109451), 4 flat washers 2.0" (part number 105909), 6 rubber cushion washers (part number 102592), 18 flat washers 3/8" (part number 100062), 30 serrated flange nuts 3/8-16 (part number 100181), 4 studs 3/8-16 x 3.00" (part number 104697), 2 double-ended studs 3/8-16 x 4.00" (part number 104686), 12 hex head screws 3/8-16 x 1.0" (part number 100040), and 2 flat washers 1/2" (part number 100118).
Yes. The step board can be modified from its original length to fit many applications. Determine the required length and cut using a saber saw, chop saw, or hack saw. After cutting, use flat black paint to touch up the exposed cut ends.
Yes. You must remove the factory front, center, and rear body mount bolts on the right side of the vehicle. These factory bolts will not be reused. Install the mounting brackets using the supplied M12 hex head bolts and washers as specified in the installation instructions.
1. Slide the appropriate number of support braces (item #2) into the channel of the step board (item #1). 2. Slide the end cap (item #3) over the front and rear of each step. 3. Using the supplied #8 x 1/2" self-drilling tek screw (item #8), screw the end cap to the bottom of the step. 4. Set the step on the mounting brackets and slide each support brace over the top of each mounting bracket. 5. Attach the flat spacer plate (item #4) to the bottom of the step between the support brace and the top of the mounting bracket. 6. Attach using the supplied 5/16-18 x 1" carriage bolt, washer, and flange nuts (items #5, 6, 7).
Before attaching the step to the brackets, slide the appropriate number of support braces (item #2) into the channel of the step board (item #1). Then, when setting the step on the mounting brackets, slide each support brace over the top of each mounting bracket. The flat spacer plate (item #4) is then attached to the bottom of the step between the support brace and the top of the mounting bracket.
1. On the short threaded end of the load reaction stud (3" stud for rear, 4" stud for front), install a 3/8" serrated flange nut (item #16) backwards to the bottom of the thread. 2. Install a 3/8" flat washer (item #15) and rubber cushion washer (item #14) tight against the serrated flange nut. The end of the stud must be recessed in the rubber washer approximately 3/16". 3. On the long threaded end of the stud, install a 3/8" serrated flange nut (item #16) backwards near the bottom of the threads.
Use the 4" stud (item #18) for the front bracket and the 3" stud (item #17) for the rear brackets. Both are 3/8-16 double-ended studs, but the different lengths accommodate the different mounting locations on the vehicle frame.
Using an M12-110mm bolt (item #11) and a 2.0" washer (item #13), install the front mounting bracket (items #1 or #2, depending on step type) to the front body mount. Leave these fasteners finger tight initially. The bracket is mounted to the factory front body mount location after removing the original factory bolt.
Using an M12-110mm bolt (item #11) and a 2.0" washer (item #13), install the center mounting bracket (items #3 or #4, depending on step type) to the center body mount. Leave these fasteners finger tight initially. Note: This bracket is not used on Regular Cab pickups.
Using an M12-116mm bolt (item #12) and a 1/2" flat washer (item #20), install the rear mounting bracket (items #5 or #6) to the rear body mount. Leave these fasteners finger tight initially. The orientation of the rear bracket differs between Regular/Quad/Crew Cab and Mega Cab pickups—refer to Figure 1 for Regular/Quad/Crew Cab or Figure 2 for Mega Cab.
Attach the rear outboard mounting bracket (items #7 or #8) to the rear inboard mounting bracket (items #5 or #6) in the upper mounting location using three 3/8-16 x 1.0" screws (item #19), 3/8" flat washers (item #15), and 3/8" flange nuts (item #16).
1. Loosen the bolt that fastens the leaf spring to the vehicle. 2. Slide the upper mounting bracket (item #9) between the bolt head and the frame bracket. 3. Place a 3/8" bolt and washer (items #15 and #19) through the hole in the upper mounting bracket and frame bracket. 4. Fasten with a 3/8" serrated flange nut (item #16). 5. Tighten the leaf spring bolt while ensuring the upper mounting bracket is level.
Fasten the lower bracket (item #10) to the upper bracket (item #9) using a 3/8" bolt, washer, and flange nut (items #15, #16, and #19). Use the two lower holes in the upper bracket and ensure the lower bracket sits level to the front brackets.
Finger tight means tightened by hand only, without using tools. This is done during the initial mounting of the brackets to the body mounts and leaf spring shackle. All fasteners are left finger tight until the step plate is positioned correctly and the load reaction studs are properly seated, at which point they are tightened to the final torque specification of 19 LB FT.
All fasteners on the Model 415114 Grip Step must be torqued to 19 LB FT. This applies to the 5/16-18 x 1" carriage bolts, washers, and flange nuts that attach the step assembly, flat spacer plate, and mounting bracket together.
The 3/8" serrated flange nuts on either side of the load reaction stud assembly must be tightened to 19 LB FT. This is done after positioning the load reaction stud assembly so that the rubber cushion is snug against the side of the frame.
The manual does not specify a torque value for the M12 hex head bolts used to attach the front, center, and rear mounting brackets to the body mounts. These fasteners are left finger tight during initial installation and then tightened after the step plate is positioned and the load reaction studs are seated. Consult the vehicle manufacturer's specifications or contact Curt Manufacturing for the correct torque value.
The rubber cushion washer (item #14) has an outside diameter of 1.00", an inside diameter of 0.354", and a thickness of 0.75". The end of the load reaction stud must be recessed in the rubber washer approximately 3/16".
Two sizes of flat washers are used: 3/8" flat washers (item #15) with an outside diameter of 1.00", inside diameter of 0.438", and thickness of 0.083"; and 2.0" flat washers (item #13) with dimensions 2.0" x 0.509" x 0.179".
The rubber cushion washer must be recessed approximately 3/16" in the load reaction stud to provide proper isolation and load distribution between the stud assembly and the vehicle frame. This ensures the rubber cushion sits firmly against the frame side wall and properly absorbs vibration and load.
The rubber cushion must be positioned snug against the side of the frame before tightening the 3/8" flange nuts to 19 LB FT. This ensures proper load distribution and frame isolation, which is critical for the structural integrity and safe operation of the step assembly.
After installation, set the step plate in the correct position and tighten all fasteners to 19 LB FT. Verify that all fasteners are properly torqued and that the step is securely attached to the mounting brackets.
After installation, verify that the load reaction stud rubber cushion is snug against the side of the frame, and that all 3/8" flange nuts on either side of the load reaction stud assembly are tightened to 19 LB FT. Ensure all mounting brackets are level and securely fastened.
