Lockable, weatherproof storage that lives on the outside of your bed — not in it.

IP65 dust- and water-tight, rated to hold 84 lb, with two padlock points and tamper-resistant mounting hardware — the special bits ship in the kit. No drilling into your truck, universal fit, guaranteed to fit.

Unlock Your Truck's Full Potential

Our flagship Fender Racks provide customizable organization that maximizes storage without compromising space, empowering professionals and adventurers with efficient, high-quality gear management solutions.

6in x 7in MOLLE

Our smallest MOLLE - made for mounting virtually any accessory. Use 1 for small hard cases and gas cans, or pair 2 or 3 together for mounting larger items. Our press fit 1/4-20 threads make mounting easy. Shown here in a 20 degree position.

Slide Plate

The Slide Plate allows you to easily install and uninstall your accessories without having to remove the Brace and Thread Plate. It also allows for micro adjustments, no matter the size and shape of your fenders, you'll get a snug custom fit every time.

Thread Plate

The foundation of our Fender Racks, and the heart of our Advanced MTMS™ Platform. Our Thread Plate creates stability, adjustability, and a plethora of untapped accessories and modularity.

Brace

The Brace is the main contact point between your Thread Plate and your bed rail. Paired with either our Track Hardware Kit or Clamp Hardware Kit, the Brace can be mounted on 99.9% of trucks on the market. Both Track and Clamp Hardware Kits are included.

Magnetic Rubber Spacer

A breakthrough for making Fender Racks possible. The Magnetic Rubber Spacer securely mounts between your truck fender and Fender Rack MOLLE Panels to create a safe and solid mount below your bed rail. The spacer can also be applied with PPF Adhesive for aluminum body trucks. (PPF and Adhesive included)

Yes — two padlock points on the case, so you can lock the lid with your own padlocks. And the case can't simply be unbolted and walked off: the racks mount with tamper-resistant security hardware, and the special bits come in your kit. Most theft is opportunistic, and most opportunists aren't carrying the bit for it.
Not necessarily. It's much easier with the camper out, but plenty of our customers install with the camper still in the bed. It comes down to the gap between your truck and camper — if you can get your hands in there to turn a wrench, you can probably do it. Often just raising the camper on its jacks is enough. But pulling it out is easier, and that's half the point of a slide-in.
Yes — compatible with Go Fast Campers and most camper/topper brands with our Capper Lift & Seal Kit.
Never — a magnetic rubber spacer and paint protection film sit between your fender and the rack, and both remove clean if you ever take it off.
Just 1.75″ in Position 1 — clears most bed campers. Mount deeper if needed, up to 3⅝″.
