The Chase Rack System Pro Build // 6 Bike sits at the top of Big Days' shuttle lineup — the full-size-truck rig for crews that refuse to compromise. Six bikes load across the bed on a system that pairs the Base Rack and Headache Rack with six Bike/eBike Mounts, and lighting and security come already handled: a Heretic 40" LED light bar with mounts plus a storable 10' cable and lock. Every piece is designed to work as one system, ready for big groups and lap after lap.
Features
- Base Rack, Headache Rack, and six bike mounts in one complete system
- Heretic 40" LED light bar and light-bar mounts included
- Storable 10' cable and lock secures bikes at the trailhead
- Drop brackets and lower "Bike Stability" Bar included
- Fits bikes with 20"–29" wheels; rated up to 900 lb
Fitment runs by truck bed size, not year, make, or model. Big Days sizes this six-mount build for full-size trucks — think F-150, Silverado, RAM, or Toyota Tundra — and the rack fits beds measuring 40–64" between the inside rails. A few exceptions: RAM beds with the RamBox system, the Honda Ridgeline, and the Tesla Cybertruck are not compatible. Driving a mid-size truck? The Pro Build // 5 Bike is the same idea sized for Tacoma-class beds.
Chase Rack System FAQs
What trucks does the Pro Build // 6 Bike fit?
Full-size trucks — think F-150, Silverado, RAM, or Toyota Tundra. Fitment is set by bed size rather than year or trim: the system fits beds with 40–64 inches between the inside rails. Three exceptions apply: RAM beds with the RamBox system, the Honda Ridgeline, and the Tesla Cybertruck are not compatible.
What is the capacity of the 6 Bike build?
Six bikes or eBikes with 20"–29" wheels, on a platform Big Days rates for loads up to 900 pounds. Drop brackets and the lower "Bike Stability" Bar come in the box to keep a full load of bikes steady, and the storable 10' cable and lock handles security at the trailhead.
What does the Pro Build include that a Starter Build doesn't?
The Pro Build arrives shuttle-ready. Beyond the Base Rack and six bike mounts, it adds the Headache Rack, drop brackets with the lower "Bike Stability" Bar, a Heretic 40" LED light bar with mounts, and a storable 10' cable and lock — pieces you would otherwise add to a rack one at a time.
