Fitment, Shipping & Product Support
The Rock Slide Engineering R-STEP (SKU RS-1600) is the 16-inch fold-out two-step bed access system for universal truck, trailer, and utility vehicle applications. Aluminum housing, stainless steel internals, 11-gauge steel stepping surface rated for 350 lbs. Universal bracket kit includes three sets of brackets for flat surface, cross member, or high platform mounting — bracket orientation is reversible to accommodate different widths and heights. Some fabrication may be required to your specific mounting surface. Powder-coated black. Made in the USA.
This is a universal mount product — not vehicle-specific. Fabrication skill and tools may be required for installation. If you need a vehicle-specific bracket kit for a Tundra, Super Duty, or other platform, confirm bracket availability with Rock Slide Engineering before ordering.

Universal vs. Vehicle-Specific R-STEP Options
| SKU | Configuration | Fitment | Notes |
|---|---|---|---|
| RS-1600 (this listing) | Universal bracket kit | Any truck, trailer, or utility platform | Some fabrication may be required |
| RS-1610 | Ford Super Duty specific | 2017–2022 Ford F-250/F-350/F-450 — driver side in front of rear tire | No fabrication required for confirmed platforms |
If a vehicle-specific bracket kit exists for your platform, it eliminates the fabrication requirement. Text (469) 407-7538 to confirm whether a specific bracket kit is available for your truck before ordering the universal kit.
Bracket Configuration Options
| Configuration | Use Case |
|---|---|
| Flat surface mount | Mounting to flat underbed surface, trailer frame rail, or flat mounting plate |
| Cross member mount | Mounting to frame cross member — most common truck frame application |
| High platform mount | Mounting to elevated platform — taller trailer applications |
Bracket orientation is reversible within each configuration to accommodate varying widths and heights between the mounting surface and the desired step deployment position.
Critical Compatibility
| Configuration | Notes |
|---|---|
| Requires mounting surface fabrication | Some fabrication to the mounting surface may be required — intermediate to advanced fabrication skill needed. Confirm before ordering. |
| Vehicle-specific bracket availability | Vehicle-specific bracket kits may eliminate fabrication requirements. Confirm with Rock Slide Engineering for your specific platform. |
| Weight loads exceeding 350 lbs | 350-lb rating is the maximum — do not exceed. |
| Extreme cold environments | Fold-out mechanism uses stainless steel internals — confirm function range for your operating environment. |
Common Questions
Is "some fabrication required" significant?
It depends on your mounting surface. The universal bracket kit accommodates flat surfaces, cross members, and high platforms with reversible orientation. However, if your mounting surface is irregular, requires drilling, or does not align with the provided bracket geometry, additional fabrication work is required. Intermediate mechanical and fabrication skill is recommended. If you want a no-fabrication install, confirm whether a vehicle-specific bracket kit exists for your truck before ordering the universal kit.
What does the "fold-out two-step" design mean?
The R-STEP deploys as a fold-out system — two steps unfold from the housing when needed and fold back in when not in use. The housing mounts under the truck bed or to the platform. When deployed, both steps are available for bed access. When stowed, the unit sits flush against the mounting surface.
Is there a 9-inch version?
Yes — the RS-900 is the 9-inch wide version of the R-STEP. Choose the 16-inch (RS-1600) when a wider stepping surface is needed for stability, or the 9-inch when mounting space is limited.
Can I mount this on a trailer as well as a truck?
Yes. The universal bracket kit is designed for trucks, trailers, and utility vehicles. The flat surface and cross member mount configurations cover most trailer rail geometries.
The Obsidian Take
The R-STEP RS-1600 is for the builder who needs reliable 16-inch fold-out two-step bed access and wants the flexibility to mount it anywhere — truck, trailer, or utility platform — without being locked into a vehicle-specific bracket configuration. Aluminum housing, stainless internals, 11-gauge steel step, 350-lb rated, universal brackets with three configurations and reversible orientation.
The honest trade-off is fabrication. The universal kit gives you maximum mounting flexibility at the cost of potentially needing to fit the brackets to your specific mounting surface. If your platform has a vehicle-specific R-STEP bracket kit available, that kit eliminates the fabrication variable. Text (469) 407-7538 before ordering to confirm.
