Get the job done right with LUVERNE Grip Step 7" running boards. These roughneck truck side steps feature a unique expanded metal tread pattern for superior traction and a 7" width for reliable footing. They are built from aluminum alloy for exceptional, rust-free strength, and they are simple to install using high-strength vehicle-specific brackets. The rugged, expanded metal tread and angular design of Grip Step running boards truly makes them a side accessory fit for your work truck or commercial van. No matter the season, the superior traction of Grip Steps locks onto the bottom of your boots and provides safe vehicle entry and exit. Because they boast an impressive 7" width, the side steps are as comfortable as they are skid-resistant. We know the job doesn't make exceptions to keep your vehicle looking pretty, and that is why Grip Step running boards are made from aluminum and shielded in a tough powder coat finish. We use a 5052 aluminum alloy to provide maximum strength and unstoppable rust resistance. To finish things off and add a professional touch, we also apply a durable textured black powder coat and contoured black plastic end caps to further protect against dirt, moisture and other threats on the job. To make installation as simple as possible, Grip Step 7" running boards are each designed for a custom-fit installation, using vehicle-specific mounting brackets. The brackets are covered in a durable black powder coat finish and bolt onto the boards using stainless steel fasteners for long-lasting strength. This particular set of Grip Step running boards is designed to fit specific years of the Ford F150 (see application info to verify fitment). These running boards come with brackets, but the brackets are shipped separately.
Grip Step 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.

Yes, the LUVERNE Grip Step 7" x 88" Black Aluminum Running Boards, Select Ford F-150 415088-401523 (Part #FTNF415088-401523) is designed to fit the 2015-2026 Ford F-150.
The LUVERNE Grip Step 7" x 88" Black Aluminum Running Boards, Select Ford F-150 415088-401523 (Part #FTNF415088-401523) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the Model 401523 Grip Step Brackets are designed for 2015 and newer Ford F150 SuperCab and SuperCrew pickups. The installation uses factory-provided studs on the rocker panel, so no drilling is required. Confirm your truck is a SuperCab or SuperCrew model, as the manual does not list other cab styles.
The manual specifies the 401523 is designed for SuperCab and SuperCrew pickups only. Compatibility with Regular Cab or other cab styles is not stated in the manual. Contact Curt Manufacturing or your dealer to confirm fitment for other cab configurations.
No. The 401523 is a no-drill application. Installation uses factory-provided studs on the inside of the rocker panel, eliminating the need for drilling.
The kit includes: 4 step mounting brackets (552845), 8 nylon isolator washers 1.5" (108442), 8 M8-1.25 flange nuts (105859), 6 hex bolts 3/8"-16 x 1.0" (100040), 8 flat washers 3/8" (100062), 12 flange nuts 3/8"-16 (106995), 2 rubber cushion washers (102592), 2 double-end studs 3/8"-16 x 5" (104673), 2 center inboard brackets (552843), and 2 center outboard brackets (552844). The step board assembly is listed separately and is not included; refer to the step board instruction sheet for mounting.
The manual does not specify required tools. Standard tools for working with bolts, nuts and washers (such as wrenches or sockets) are typically needed, but the manual does not list them explicitly. Consult the manufacturer or an installer if you need clarification on specific tools required.
The manual does not mention battery disconnection. Since this is a mechanical bracket installation with no electrical components, battery disconnection is likely not required, but confirm with the manufacturer or installer if you have concerns.
The manual does not specify whether professional installation is required. The installation involves removing the center body mount bolt, assembling brackets and studs, and tightening fasteners. If you are comfortable working with bolts, nuts and basic hand tools, you may be able to complete the installation yourself. If you are unsure, consult a professional installer or Curt Manufacturing.
1. Install two 1.5" isolator washers, the step mounting bracket, and two M8-1.25 flange nuts over the factory studs on the inside of the rocker panel on the left side. 2. Repeat for the rear bracket on the left side. 3. Check that front and rear brackets are level and tighten all flange nuts. 4. Remove the center body mount bolt and install the center inboard bracket. 5. Attach the outboard bracket to the inboard bracket using three 3/8" hex bolts, flat washers, and flange nuts; adjust height to match your step board. 6. Assemble the load reaction studs with hardware. 7. Check that the center bracket is perpendicular to the vehicle body and tighten the body mount bolt. 8. Install the load reaction stud and tighten the outboard flange nut to 19 lb-ft. 9. Repeat steps 2–9 for the right side.
On the short threaded end of the load reaction stud (Item #9), install a 3/8" flange nut backwards onto the bottom of the thread. Then install a 3/8" flat washer and rubber cushion washer tight against the flange nut. The end of the stud must be recessed in the rubber washer approximately 3/16". On the long threaded end, install a 3/8" flange nut backwards to near the bottom of the threads. This assembly is then installed into the center inboard bracket.
The outboard flange nut on the load reaction stud must be tightened to 19 lb-ft. This is the only torque value specified in the manual for the 401523 installation.
The manual states to tighten the center body mount bolt per the manufacturer's specifications but does not provide a torque value. This likely refers to Ford's specification for the original bolt. Consult your Ford service manual or contact Curt Manufacturing for the correct torque value.
The manual does not specify a torque value for the M8-1.25 flange nuts that attach the step mounting brackets to the factory studs on the rocker panel. The instruction is to tighten them after checking that the front and rear brackets are level. Contact Curt Manufacturing for the recommended torque specification.
The manual does not specify a torque value for the three 3/8" hex bolts (Item #5) that attach the outboard bracket to the inboard bracket. The instruction is to adjust the height to match your step board and then tighten the bolts. Contact Curt Manufacturing for the recommended torque specification.
The height is adjusted by loosening the three 3/8" hex bolts that connect the outboard bracket (Item #11) to the inboard bracket (Item #10). Slide the outboard bracket up or down to match your step board height, then tighten the bolts. Refer to the step board instruction sheet for specific mounting details.
When installing the load reaction stud into the center inboard bracket, the rubber cushion washer (Item #8) must be positioned so it is in firm contact with the vehicle frame. This is adjusted by moving the inboard flange nut up or down the stud until the washer is snug against the frame. This ensures proper load distribution and support.
The manual requires that the center bracket be checked for perpendicularity to the vehicle body before tightening the body mount bolt. This ensures proper alignment and load distribution of the step assembly. Use a level or square to verify perpendicularity before final tightening.
After installation, verify that: (1) the front and rear brackets on each side are level, (2) the center bracket is perpendicular to the vehicle body, (3) the rubber cushion washer is snug against the vehicle frame, and (4) all fasteners are tightened to specification. The manual does not specify post-installation retorque intervals or maintenance checks beyond these initial verifications.
No. The step board assembly (Item #1) is listed separately in the parts list. The 401523 kit includes only the brackets and hardware. Refer to the instruction sheet included with your step board assembly for mounting instructions.
Yes, for 2015+ F150 SuperCab and SuperCrew models. The installation is no-drill and uses factory rocker panel studs.
No. This is a no-drill application that uses factory-provided studs on the rocker panel.
The outboard load reaction stud flange nut is tightened to 19 lb-ft. Torque values for other fasteners are not provided; contact the manufacturer for specifications on the rocker panel studs, center body mount bolt, and outboard bracket bolts.
Yes. Step 5 requires removal of the center body mount bolt to install the center inboard bracket. The bolt is then reinstalled and tightened per manufacturer specifications in Step 8.
Loosen the three 3/8" hex bolts connecting the outboard bracket to the inboard bracket, slide the outboard bracket to the desired height, and retighten the bolts. Refer to your step board instruction sheet for final mounting.
The rubber cushion washer must be recessed approximately 3/16" into the flange nut on the short threaded end. The washer must then be snug against the vehicle frame when installed. This ensures proper load distribution.
