For overlanders, mountain bikers, dirt bike riders, and truck owners who shuttle gear to remote trails, the Big Days Chase Rack System in the DH Race Build configuration offers a highly capable mountain bike rack option. This modular solution combines a robust base rack with mounts for three mountain bikes and one motorcycle. Users can quickly switch between loads without losing truck bed usability or full tailgate closed function.

The system bolts directly to most bed rails on full-size and mid-size trucks. This keeps the hitch free for towing trailers, campers, or recovery gear with your tailgate closed. Backup camera visibility and off-road angles are preserved. Riders can transport bikes or motos with the tailgate closed, maintaining full bed access for tools, gear, or camp supplies during long overland trips or local Arizona shuttle days.

Modular Engineering: The Ultimate Mountain Bike Rack for Trucks

The integrated T-Track system allows for fast mount changes. Swap from bikes to moto in minutes with this mountain bike rack, requiring only basic tools for the initial assembly. This modularity is perfect for variable adventures—carry three trail bikes for park laps, then swap to a dirt bike easily for single-track rides. With secure attachment, bike movement is minimized, cutting the risk of frame or component damage when off-roading at speed.

Robust 3/16" A36 steel risers, 6560 T6 alloy cross bars, and 1/4" 5052 alloy mounts ensure the rack absorbs vibrations and impacts. Whether on rough forest roads, rocky climbs, or dusty washes near Phoenix, this mountain bike rack is built to last. The full rack weighs only 70 lbs and sits low-profile at 20" without mounts (26" with mounts, about 42" loaded). The lower cross bar can be removed for 100% bed access—no more limitations when not hauling gear.

World Champion DH racer Jackson Goldstone uses this mountain bike rack system for shuttling up to six bikes or switching to moto loads. This proves its value in demanding riding scenarios. Overlanders and truck owners get all the flexibility—no need for separate hitch racks or truck bed bike rack solutions that block towing or reduce clearance.

Setup is quick—install in 30-60 minutes using included brackets and basic hand tools (a drill is required for bolting onto bed rails). The rack works with tonneau covers featuring 2"+ exposed bed rail (folding or retractable work best; adapters available for T-Track style covers). Each mountain bike rack order includes a motorcycle ramp and storage bracket for solo or team loading of heavier two-wheelers.
