Chase Rack System - Starter Build // 5 Bike
The Starter Build // 5 Bike pairs the Big Days Chase Rack System Base Rack with five bike mounts, drop brackets, and a lower bike-stability bar — a purpose-built shuttle rig that hauls five mountain bikes up top while the bed below stays open for coolers, tools, and camp gear. It's the cleanest way to run laps on shuttle days and still use your truck like a truck the rest of the week.

Fitment runs by truck bed size, not year, make, and model: Big Days lists this build for 4'10" to 8' beds with 40"–64" inside width, which covers most mid-size and full-size trucks.

Chase Rack System FAQs
What truck beds does the Starter Build // 5 Bike fit?
Truck beds from 4'10" to 8' long with inside widths of 40" to 64" — fitment runs by bed size rather than year, make, and model, which covers most mid-size and full-size pickups. The 61" upper crossbar can also be trimmed by request for narrower setups.
How much weight can this rack carry?
The Chase Rack System is rated for up to 900 pounds of cargo, and the rack itself weighs 70 pounds. Five mountain bikes land well under that rating, and the drop brackets and lower bike-stability bar steady the load, so the setup stays solid on washboard shuttle roads.
How does the Starter Build differ from Essential and Pro builds?
Starter builds keep it simple: the Base Rack plus your mounts. Essential builds add loading gear such as the in-bed moto ramp and offset kit, while Pro and Elite builds layer on items like the Headache Rack, lighting, and off-road storage. Every tier starts from the same 900 lb-rated Base Rack.
