Westin Step Nerf Bar Kits: Where Form Meets Function
When it comes to blending cab accessibility with rugged good looks, few manufacturers have built the reputation that Westin Automotive has in the Step Nerf Bar Kit category. With over 215 kits in the lineup, Westin delivers purpose-built solutions for trucks, SUVs, and Jeeps — each designed as a complete, vehicle-specific package that removes the guesswork from installation.
A Deep Bench of Product Lines
What sets Westin apart is the sheer breadth of its nerf bar families, each engineered for a different driver profile.
- R5 & R5 XD Nerf Step Bars — The flagship R5 family is one of Westin's most recognized lines. The standard R5 features a 5-inch wide step area with oversized step pads, while the R5 XD takes accessibility further by dropping the step surface a full 3 inches lower to the ground for easier entry and exit. Tested and engineered in the USA, R5 XD bars are available in polished stainless steel backed by a lifetime warranty, or textured black powder-coated aluminum backed by a 3-year warranty. Both versions come complete with driver's side bars, passenger side bars, and a vehicle-specific mount kit, mounting directly to the rocker panel with injection-molded bracket covers for a clean, high-end appearance.
- R5 M-Series XD Wheel-to-Wheel — For crew and extended cab owners who want full-length coverage, the R5 M-Series XD maintains all the premium features of the original R5 M-Series, including extra-wide 5-inch skid-resistant step pads, a third step for easier cargo bed access, and an optional light kit for better visibility in inclement weather or darkness.
- R7 Nerf Step Bars — Westin's R7 Nerf Step Bars feature oversized step pads and factory-style traction grooves, sold in complete kits that include driver and passenger-side boards, a vehicle-specific mount kit, and injection-molded bracket covers.
- Outlaw & Outlaw Drop Nerf Step Bars — Built for the off-road crowd, the Outlaw Nerf Step Bars offer a balance of function and strength, engineered to fit tightly against rocker panels. They feature 16-gauge steel with a coarse step surface and 2-inch diameter tubing, with bolt-on installation, an e-coated base coat, and a textured black powder-coat finish. The Outlaw Drop variant adds mandrel-bent 1.5-inch diameter steel tube construction and a distinctive 4-inch drop die-stamped step plate that helps knock mud, dirt, and debris from your feet before entering the cabin.
- Pro Traxx Oval Nerf Bars — The Pro Traxx 4 Oval Nerf Step Bars feature a 4-inch oval tube with a heavy-duty step pad for a wider, more secure step area, with 30-degree factory-style bends and seamless domed ends — no exposed bolt heads. Bolt-on installation with a mount kit is included, and no drilling is required on most applications.
- Signature 3 Nerf Step Bars — The Signature 3 series uses 3-inch diameter mild steel construction with vehicle-specific step designs and mounting techniques, and is available in black powder coat or chrome finish.
Materials, Finishes, and Fit
Westin manufactures its steps from premium alloys, including corrosion-resistant stainless steel, lightweight cast aluminum, and durable carbon steel. Finishes include polished, gloss black powder coat, and textured black powder coat, ensuring a product that complements every build. Westin finishes even undergo scientific salt spray testing to ensure superior rust protection.
Westin step nerf bar kits are vehicle-specific, meaning they're specially engineered to fit particular applications — all brackets and hardware are direct fits, offering simple, no-drill installation. Every kit ships with everything needed to complete the install, so there's no hunting for separate mounting hardware.
