Nerf Bars & Running Boards — Running Boards and Nerf Bars for Trucks and SUVs

Running boards and nerf bars make entry and exit easier — a practical necessity on lifted trucks where the step-in height can exceed 24" from the ground. Beyond pure function, they protect the door sills and rocker panels from dings, rocks, and trail debris. On work trucks, they're a daily convenience. On lifted builds, they're borderline essential for passengers who aren't six feet tall.

Running Boards vs. Nerf Bars

Running boards

Full-length step platforms running along the lower edge of the door sills. Broad flat surface — easier to step on, more comfortable for multiple entry/exit points. Common in OEM-style and replacement applications.

Nerf bars (tube steps)

Steel or aluminum tube running along the rocker, with step pads at the door locations. More off-road durable — narrower profile reduces clearance loss and is less likely to catch terrain. More common on lifted trucks and off-road builds.

Power running boards

Motorized boards that retract flush with the body when not in use and extend when the door opens. Factory option on many full-size trucks; aftermarket versions available. Maximum ground clearance when retracted.

Materials and Finish

• Stainless steel: Corrosion-resistant, bright finish. Common on factory-replacement and styling-focused applications.
• Black powder-coated steel: Durable, matte finish. Common on off-road and truck-focused applications. Some surface rust on chips over time in high-moisture environments.
• Aluminum: Lightweight, corrosion-resistant, common in OEM-replacement boards.

Step Surface

Check the step pad material and coverage area — a step bar with small non-slip pads in the wrong location for your door jamb is functionally useless in wet conditions. The best step pads are wide, full-grip aluminum tread or molded rubber covering the full usable step area.

Fitment

Running boards and nerf bars are vehicle-specific — cab length (regular, extended, crew), body configuration, and rocker mount locations all vary. Every product listing includes a fitment table by year, make, model, cab configuration, and trim.

About Bull Strap's Catalog

Bull Strap sources from Turn14 Distribution, one of the largest automotive aftermarket distributors in North America, carrying over 103,000 products across hundreds of brands. Every product listing includes a complete fitment table by year, make, model, and trim so you can confirm compatibility before you order. The catalog covers suspension, wheels and tires, exterior accessories, interior accessories, lighting, exhaust, engine performance, recovery gear, and every major truck accessory category.

Bull Strap's catalog is built around the vehicles that matter most to truck and off-road owners. Full-size trucks from Ford, Ram, Chevrolet, and GMC represent the largest portion of the fitment data. Toyota trucks and SUVs including the Tacoma, Tundra, and 4Runner are strongly represented. Jeep Wranglers, Gladiators, and off-road-specific platforms round out the coverage. Midsize trucks including the Colorado, Canyon, Ranger, and Frontier are covered where Turn14 carries fitment data for the category.

Fitment by Vehicle

Every product in the Bull Strap catalog includes fitment data from the Turn14 distribution system, verified against vehicle-specific mounting configurations, dimensions, and compatibility requirements. Coverage spans the following platforms:

• Ford F-150 (2004-present), F-250 and F-350 Super Duty (2005-present), Bronco (2021-present), Ranger (2019-present)
• Ram 1500 (2009-present), Ram 2500 and 3500 (2010-present)
• Chevrolet Silverado 1500 (2007-present), Silverado 2500HD and 3500HD (2011-present), Colorado (2015-present)
• GMC Sierra 1500 (2007-present), Sierra 2500HD and 3500HD (2011-present), Canyon (2015-present)
• Toyota Tacoma (2005-present), Tundra (2007-present), 4Runner (2003-present), Sequoia (2008-present)
• Jeep Wrangler TJ (1997-2006), Wrangler JK (2007-2018), Wrangler JL (2018-present), Gladiator JT (2020-present)
• Nissan Frontier (2005-present), Titan (2004-present), Titan XD (2016-present)

Always verify fitment on the individual product page before ordering. Trim level, cab configuration, bed length, engine, and drivetrain all affect compatibility for vehicle-specific parts.

The catalog is large and search sometimes surfaces only a portion of available inventory.

Choosing Between OEM Replacement and Performance Upgrade

The aftermarket parts market offers two fundamentally different value propositions for almost every part category: OEM-quality replacement and performance upgrade. Understanding which one your vehicle and use case actually needs saves money and prevents buying the wrong part.

OEM-quality replacement parts are engineered to restore a vehicle to factory specification after a component fails or wears out. Brands like Moog, Dorman, Monroe, and Gates occupy this space. These are often higher quality than the original factory parts at a lower cost than dealer pricing. The goal is factory-level performance, not improved performance.

Performance upgrade parts are engineered to exceed factory specifications in specific ways. Improved damping, greater strength, better adjustability, extended service life under severe use, or expanded travel for lifted applications. Brands like Bilstein, Fox, Carli Suspension, ICON Vehicle Dynamics, and Eibach occupy this space. Higher cost, but measurable improvement in the targeted performance areas.

Match the part to the actual use case. A daily driver with worn shocks needs OEM-quality replacement, not a remote-reservoir performance shock at three times the price. A dedicated off-road truck being built for serious trail use needs performance upgrades, not OEM-spec replacements that will wear faster under the increased demands of the build.

Bull Strap's USA-Made Limit Strap

Bull Strap's signature product is the USA-made limit strap, engineered and manufactured in the United States specifically for lifted trucks and serious off-road builds. Limit straps cap the droop travel of lifted suspension systems, protecting CV axles, brake lines, and ABS sensor wires from overextension at full droop on the trail or in a ditch. They are one of the most critical and most overlooked components on any seriously lifted truck. Every lifted truck with independent front suspension or a solid axle setup running more than two inches of lift should have limit straps protecting the drivetrain.

Every limit strap from Bull Strap is made in the USA using high-tenacity polyester webbing, solid steel hardware, and heat-shrink tubing on every connection point. Built to withstand the repeated load cycles of serious off-road use without stretching, degrading, or failing. The Turn14 catalog of 103,000 products is the primary product surface at Bull Strap, but the limit strap is where the brand started and remains the product that defines the brand.

Installation and Compatibility

Every product listing in this collection includes installation information where the manufacturer provides it. Difficulty ratings, required tools, and estimated installation time are on product pages where the manufacturer supplies that data. For parts that require specific vehicle knowledge or alignment work, professional installation is recommended if you do not have the mechanical background and equipment to do the job correctly. Torque specifications matter: under-torqued fasteners back out under vibration; over-torqued fasteners strip threads or crack housings. Always follow manufacturer torque specs rather than estimating from feel or experience with a different part.

For straightforward bolt-on accessories and direct replacement parts, most installations are within reach of a mechanically capable owner with basic hand tools, a floor jack, and safety stands. Jack stands are not optional on any job that requires getting under a lifted vehicle. Use them every time without exception.

Returns and Fitment Verification

Fitment errors are the most common cause of returns in the truck accessory market. The best way to avoid them is to verify fitment from the product page before ordering, cross-checking your vehicle's year, make, model, trim, cab configuration, bed length, and drivetrain against the fitment table. When a product page lists multiple trim levels or configurations, confirm your specific trim is listed before purchasing. If you are not certain, contact Bull Strap before placing the order. Avoiding a return saves time, shipping cost, and the wait for the correct part to arrive.
