The Chase Rack System Pro Build // 5 Bike is Big Days' top shuttle setup for mid-size trucks — built for crews running laps all day who want the whole rig sorted in one box. It combines the Base Rack, Headache Rack, and five Bike/eBike Mounts into one dialed system, so five bikes ride above the bed while roughly 40 cubic feet of Gear Cave space stays open underneath for packs, pads, and coolers.
Features
- Complete shuttle package: Base Rack, Headache Rack, five bike/eBike mounts
- Heretic 52" light bar and light-bar mounts included
- Drop brackets and lower "Bike Stability" Bar steady loaded bikes

Fitment goes by truck bed size, not year, make, or model, and this five-mount layout is the version Big Days sizes for mid-size beds — think Toyota Tacoma, Ford Ranger, and Jeep Gladiator. Running a full-size truck and a bigger crew? Step up to the Pro Build // 6 Bike, or add a Storable Bike Lock for trailhead stops. Browse the rest of the lineup in our chase racks collection.
Chase Rack System FAQs
Will the Pro Build // 5 Bike fit my truck bed?
Yes, if your bed measures 40–64 inches between the inside rails and runs 4'10" to 8' long — fitment goes by bed size, not year, make, or model. Big Days sizes this five-mount layout for mid-size beds, so trucks in the Tacoma, Ranger, and Gladiator class are the natural match.
How many bikes can it carry, and what is the weight limit?
Five bikes or eBikes on a system rated for loads up to 900 pounds; the rack itself weighs 70 pounds. Drop brackets and the lower "Bike Stability" Bar are included to keep loaded bikes steady between laps, and about 40 cubic feet of Gear Cave space stays free below for gear.
What is the difference between the Pro Build // 5 Bike and the Pro Build // 6 Bike?
Size and spec. The 5 Bike is sized for mid-size truck beds and includes a Heretic 52" light bar; the 6 Bike is built for full-size trucks, carries one more mount, runs a 40" light bar, and adds a storable 10' cable and lock. Both are built around the same Base Rack, Headache Rack, and 900-lb-rated platform.
