N-Fab Epyx Steps – Aluminum Side Steps with Precision Cab Length Fit
Our Epyx Steps bring precision-engineered aluminum side access to your truck or SUV with cab-length fitment that follows your roofline for a seamless OEM look. Each step features an extruded aluminum construction with integrated hoop-style brackets and an aggressive diamond-tread surface that sheds mud, snow, and debris. We manufacture every Epyx step in the USA to match your exact year, make, and model, ensuring drop-in installation with vehicle-specific mounting hardware included.
The Epyx platform delivers confident footing in all weather conditions while maintaining a lightweight profile that won’t impact fuel economy or suspension geometry. Our textured black powder coat finish resists corrosion and UV fading, and the low-profile design maintains ground clearance for off-road travel. Whether you’re stepping into a crew cab or extended cab, Epyx Steps provide a stable 6-inch-wide stepping surface positioned exactly where you need it.

- Cab-length design follows roofline for OEM appearance
- Aggressive diamond-tread surface for all-weather traction
- 6-inch-wide stepping platform with recessed tread channels
- Textured black powder coat finish resists corrosion and UV damage
Aluminum Construction & Finish Durability
We build every Epyx step from extruded 6063-T6 aluminum alloy, a heat-treated grade that delivers exceptional strength-to-weight ratio and natural corrosion resistance. The extrusion process creates uniform wall thickness throughout the step tube and integrated hoop brackets, eliminating weak points common in welded assemblies. Our textured black powder coat finish is applied after a multi-stage prep process that bonds the coating directly to the aluminum substrate.
The diamond-tread pattern isn’t just stamped on top—it’s part of the extrusion profile itself, so the aggressive texture won’t wear smooth or separate over time. Recessed tread channels allow water, mud, and snow to drain away rather than pooling on the step surface. The powder coat formulation includes UV inhibitors that prevent fading and chalking even under constant sun exposure in desert and coastal environments.
Cab-Length Fitment & Mounting System
Custom Sizing for Your Truck
Epyx Steps are engineered in cab-length configurations that terminate at your rear door rather than extending to the tailgate. This design follows the roofline and body contours of your specific truck model, creating a factory-integrated appearance. Extended cab, crew cab, and SuperCrew applications each receive purpose-built step lengths that align with door openings and rocker panel geometry.
Integrated Hoop Brackets
The mounting system features hoop-style brackets extruded as part of the main step tube rather than bolted or welded afterward. These hoops wrap around the step and connect to vehicle-specific mounting plates that attach to existing frame holes and pinch-weld points. Most installations require no drilling—just bolt the supplied hardware into factory locations using the included brackets and fasteners. The hoop design distributes step-in forces across multiple contact points, preventing the twisting and sagging common in straight-bracket systems.
Installation Requirements & Compatibility
Each Epyx step kit ships with vehicle-specific mounting hardware, brackets, and detailed instructions matched to your truck’s year, make, model, and cab configuration. Installation typically takes 60-90 minutes with basic hand tools—no cutting, welding, or fabrication required. We include all necessary bolts, washers, and mounting plates calibrated for your frame geometry.
Compatibility extends across full-size and mid-size truck platforms from Ford, Chevrolet, GMC, Ram, Toyota, and Nissan. The cab-length design works with both 2WD and 4WD drivetrains and accommodates factory running boards when removed prior to installation. Ground clearance remains similar to stock—the step sits close to the rocker panel to minimize departure angle reduction during off-road use. Epyx steps do not interfere with tow hooks, skid plates, or factory air dam components on compatible vehicles.

Common Questions About N-Fab Epyx Steps
Cab-length Epyx steps terminate at the rear door edge, following your truck’s roofline for an OEM-integrated appearance. They provide stepping access at the front and rear doors while maintaining a streamlined profile.
Wheel-to-wheel versions extend from the front wheel well to the rear wheel well, covering the entire rocker panel length. This design offers continuous stepping access along the full side of the truck but adds visual length. Both use the same aluminum construction and tread pattern—the choice depends on your preference for coverage versus aesthetics.
Standard Epyx steps work with mild leveling kits up to 2 inches, maintaining reasonable step-in height. For lifts exceeding 2 inches, we recommend our Epyx MultiStep system, which includes a drop-down extension that lowers when the door opens.
The MultiStep provides the same cab-length fitment and aluminum construction as standard Epyx steps but adds powered deployment for easier access on lifted applications. Both systems use vehicle-specific mounting brackets that accommodate factory and aftermarket suspension geometry.
Most applications install using existing factory frame holes and pinch-weld mounting points with no drilling required. The vehicle-specific bracket kit includes mounting plates designed to bolt directly into locations used by the factory or delete existing running board mounts.
A small number of older truck models may require one or two holes for bracket positioning—your application-specific instruction sheet will note this during the ordering process. We provide detailed drilling templates and bit specifications when required, though the majority of installations are truly bolt-on.
Epyx steps typically sit 1-2 inches lower than your factory rocker panel, minimizing ground clearance reduction. The close-to-body design positions the step tube near the pinch weld rather than hanging several inches down like traditional round tube steps.
Departure angle impact is minimal because cab-length steps terminate before the rear axle. Most users see less than 1 inch of effective clearance loss in off-road situations. The aluminum construction is impact-resistant but will bend rather than tear mounting points if struck, protecting your frame and body mounts.
You’ll need to remove existing running boards before installing Epyx steps. The mounting locations often overlap, and dual installation would create interference. Most factory running boards unbolt easily—they typically use 4-6 mounting points per side.
Save your factory hardware if you plan to reinstall running boards in the future. Epyx steps use vehicle-specific brackets that may occupy different mounting points, so retaining original hardware ensures you have complete reinstallation capability. The Epyx installation typically takes the same time as factory running board removal and replacement.
Routine cleaning with soap and water is sufficient for most conditions. The powder coat finish resists staining, and the open tread design self-cleans during normal driving. We recommend periodic inspection of mounting bolts—retorque to specification after the first 500 miles, then check annually.
In areas with heavy road salt use, rinse the steps and mounting hardware periodically during winter months to prevent salt accumulation in bracket recesses. The aluminum won’t rust, but flushing salt away extends the life of steel mounting bolts. Apply a light coating of anti-seize compound to bolt threads during installation to prevent corrosion-lock in the mounting points.
Yes, cab-length Epyx steps terminate before the bed area and do not interfere with tonneau covers, truck caps, or bed extenders. The step ends at the rear cab corner, leaving full access to bed-mounted accessories.
Some full-length tonneau covers with integrated side rails may require minor adjustment of the rail position to clear the step’s rear hoop bracket. Soft roll-up and folding covers install normally without modification. Hard tri-fold and retractable covers typically have no interference because their mounting systems attach to the bed rail rather than extending down to rocker panel height.
