The ARB Base Rack Deflector (arb17950020) is a versatile, low-profile roof rack solution specifically designed for the 2018-2023 Jeep Wrangler JL Unlimited models equipped with the factory hardtop. Using the proven internal frame from ARB’s classic roof racks, this system now includes BASE Rack-specific blade brackets and a dedicated mounting kit for a perfect fit with the 61" x 51" BASE Rack (PN 1770020).

The innovative dovetail mounting system runs along the rack’s perimeter and internal beams, offering unmatched flexibility for adding, repositioning, or removing accessories without disturbing the entire load. This design also resists dust and debris build-up, unlike traditional roof rack channels. Accessories such as recovery boards, Hi-Lift Jack mounts, rollers, and even an ARB BASE Rack LED light bar (PN 1780500) can be installed quickly and securely.

The rack’s low-profile clearance of just 1.37 inches above the roof and minimal added vehicle height of only 2.75 inches preserves your Jeep’s rugged stance and garage compatibility. Best of all, the front section of the OE hardtop remains removable with the rack in place, maintaining your Wrangler’s open-air freedom.
