N-Fab Adjust Step — Telescoping Side Step System
We built the Adjust Step for drivers who refuse to choose between ground clearance and easy cab access. This telescoping side step extends when you open the door, then retracts flush against the rocker panel when you close it—giving you 8 inches of reach exactly when you need it and zero drag or obstacle risk on the trail.
Our engineers paired aircraft-grade aluminum rails with a composite step tread that sheds mud, snow, and ice without cracking in sub-zero temps. The motorized deployment system runs on your truck's existing 12V circuit and includes an override switch for manual retraction in the rare event of a power fault. Whether you're climbing into a lifted F-250 in work boots or helping a passenger board in street shoes, the n fab adjust step meets you where you are—then disappears until the next stop.
- 8-inch telescoping extension activated by door sensors
- Aircraft-grade 6061-T6 aluminum frame with reinforced mounting brackets
- Composite tread surface rated for 400 lbs per step, tested to -40°F
- Motorized deployment in under 2 seconds; manual override included
- Sealed bearing system prevents dirt and moisture intrusion
Materials & Construction
We start with extruded 6061-T6 aluminum—the same alloy spec’d for commercial aircraft components—and form it into a double-wall rail that resists torsional flex under repeated cycle loads. Each mounting bracket includes a steel insert that distributes clamp force across the frame rail, eliminating the stress cracks we’ve seen in competitors’ cast-aluminum designs.
The step tread itself is a glass-filled nylon composite molded around a stainless steel armature. That combination delivers the grip of rubber without the UV breakdown, and the cold-weather performance of metal without the slip hazard. We’ve torture-tested these treads through 50,000 extension cycles in our Arizona lab and another 10,000 in a Minnesota winter—zero surface cracking, zero delamination.
Installation & Fitment
Vehicle-Specific Brackets
We design every Adjust Step kit around your truck’s exact frame geometry. That means the mounting points align with factory holes on most late-model pickups—no drilling, no cutting, no custom fab work. You’ll receive four bolt-on brackets, a pre-wired harness that plugs into your OBD-II port, and a door-sensor module that taps your dome-light circuit.
Installation typically takes two hours in a home garage with basic hand tools. We include torque specs for every fastener and a step-by-step manual with photos shot on your specific make and model. If you prefer professional installation, any reputable truck accessory shop can handle the job in under 90 minutes.
Operation & Safety Features
The deployment sequence begins the instant your door latch disengages. A Hall-effect sensor detects the unlatch event and signals the motor controller, which extends the step to full travel in 1.8 seconds. An internal limit switch halts the motor at maximum extension, and a second switch triggers retraction when the door closes and latches.
If the step encounters an obstacle mid-cycle—a curb, a rock, a dog—the motor’s built-in overload clutch disengages before the frame bends. The system defaults to the retracted position, so even if you lose power while the step is extended, the spring-return mechanism pulls it flush within three seconds.

Questions about the N-Fab Adjust Step
In most cases, yes. The Adjust Step mounts to the frame rail behind your rocker panel, so it clears slider tubes that sit flush or slightly outboard. If your sliders extend more than 2 inches past the rocker, measure the available space before ordering. Our tech team can confirm fitment if you send us a photo of your current setup.
We also offer a slim-profile bracket kit for trucks with aggressive slider or armor configurations. Just note your setup in the order comments and we'll include the right hardware.
The composite tread surface is designed to shed frozen precipitation as the step retracts. The textured pattern prevents ice adhesion, and the mechanical action of the hinge breaks off any buildup before it can jam the mechanism. We've tested the system through freeze-thaw cycles down to -40°F with zero failures.
If you live in an area with heavy road salt, we recommend an annual rinse of the hinge points and a light coat of silicone spray on the pivot pins. That's the only cold-weather maintenance you'll need.
Most DIYers with basic hand tools can complete the installation in about two hours. The kit includes vehicle-specific brackets that bolt to factory frame holes on late-model trucks, and the wiring harness is plug-and-play. You'll need a socket set, a drill for zip-tie anchors, and a test light to verify your door-sensor tap.
If you're not comfortable splicing into your dome-light circuit, any truck accessory shop or mobile installer can handle the electrical portion in under an hour. We provide torque specs and step-by-step photos in the manual.
The Adjust Step includes a spring-return mechanism that automatically retracts the step to the flush position if power is lost. Even if the motor itself fails, the spring pulls the assembly tight against the rocker panel within three seconds—so you won't drive around with a dragging step.
Our motor carries a five-year warranty, and we stock replacements at our Texas warehouse. If you ever need a swap, the motor housing unbolts in five minutes and the new unit plugs directly into the existing harness.
No. The step assemblies mount forward of the rear axle and don't extend past the rocker panel when retracted, so they clear hitch receivers, bike racks, and cargo carriers. When deployed, the step pivots perpendicular to the door sill and retracts before you shift into gear, so there's no conflict with trailer tongue or tow-bar geometry.
If you run a hitch-mounted step for bed access, the Adjust Step actually works in tandem—giving you assisted entry at both the cab and the tailgate.
Each step pad is rated for 400 pounds of static load, tested per SAE J2875 protocols. That's more than enough capacity for any adult stepping up into the cab, even with a heavy tool belt or gear bag. The aluminum frame itself is engineered to handle dynamic loads well beyond that rating, so you won't see flex or sag under normal use.
We've also tested the deployment motor under continuous 300-pound loads for 10,000 cycles without performance degradation. The system is built for daily use on work trucks, not occasional weekend errands.
Yes. We include an under-seat override switch that locks the step in the retracted position regardless of door state. Flip the switch before you hit the trail and the motor ignores door-sensor inputs, keeping the step tucked flush for maximum clearance.
When you return to pavement, flip the switch back to auto and normal door-triggered operation resumes. It's a two-second toggle that gives you full control over when the step deploys.
