Frequently Asked
How long does the roof rack take to install?
Most customers install in 45–60 minutes. The rack uses your factory roof rail mounting points — no drilling, no adhesive. A torque-spec guide is included so you can tighten to OEM spec and drive away the same day.
Platform-style or low-profile slimline — which is this?
This is a full platform-style rack with a continuous slotted deck for mounting accessories anywhere along its length. That means rooftop tents, awnings, cargo boxes, traction boards, jerry cans, and light bars all bolt directly to the deck — no adapters needed.
What are the load ratings — static vs dynamic?
Static load (parked — e.g., rooftop tent with sleepers): up to 1,000 lb. Dynamic load (driving): up to 300 lb. These ratings exceed the IIHS rack testing standard and match what ARB and Front Runner publish for their competing platforms.
Will my rooftop tent / awning / light bar bolt up?
Yes. The slotted deck uses the industry-standard 8mm T-slot channel compatible with iKamper, Roofnest, CVT, Smittybilt, ARB, Rhino-Rack, and every major awning and LED bar brand. Any accessory that bolts to a Front Runner Slimline or Prinsu rack will bolt to ours.
Will it fit my truck?
This rack is cut for the specific year, make, and model shown in the fitment box at the top of this page. It uses your factory mounting locations — so if your truck matches that spec, the rack will bolt on with the factory-point feet in the box.
Shipping and warranty?
