The Big Days Chase Rack System in the Pro Build 3 Moto configuration delivers a modular, heavy-duty chase rack for long-distance off-road trips and remote travel. This rack is engineered for desert racing, emphasizing strength and lasting reliability. It secures up to three motorcycles or dirt bikes while allowing the tailgate to close. This preserves full truck bed access, maintains hitch use, and keeps the rear camera unobstructed for towing and maneuvering difficult terrain.

The foundation of this truck bed moto rack is a flexible T-Track system installed across its cross bars. The T-Track enables fast, tool-free swaps between motorcycle mounts, RotopaX carriers, light bars, and various accessories. Its modular setup makes it perfect for overlanding, dual-sport trips, and multi-day hauls. The riser legs bolt directly to the bed rails; while some trucks need drilling, this ensures the rack withstands vibration, heat, and rough off-road use.

This Baja-inspired system outfits the chase rack for demanding distance and durability. It comes with three motorcycle mounts and an offset kit for weight balance. Six tie-down points provide secure bike transport. Included are ramp storage mounts, two DLX RotopaX mounts holding a 4-gallon fuel can and a 1-gallon water jug. The rack also features mounts for a 40" Heretic light bar. If you need maximum bed space, the lower cross bar removes easily.

Tonneau cover compatibility expands the truck bed moto rack's usability. It works with most folding, retractable, and roll-up covers that leave enough exposed rail. Adapters for T-Track compatible covers are available separately. Installation is simple, taking about 30-60 minutes with the supplied brackets and regular tools. This system fits many trucks: full-size models like Ford F-150/F-250, Chevrolet Silverado, RAM, and Toyota Tundra, as well as mid-size models like Tacoma, Ranger, and Gladiator—accommodating bed widths from 40 to 64 inches.
