The Chase Rack System Base Rack is the platform the whole Big Days lineup builds on — a race-style truck bed chase rack from the rider-founded crew based in Orem, Utah, designed to haul dirt bikes, mountain bikes, and gear without giving up the bed underneath. Up to 900 lbs rides on 3/16" A36 steel risers and 6560 T6 alloy cross bars, and the T-track accepts every Big Days mount: add a Bike/eBike Mount for shuttle laps, a Motorcycle/eMoto Mount for race weekends, or run it bare as a work rack.
Features
- Up to 900 lb load capacity; the rack itself weighs 70 lbs
- 61" trimmable upper bar and 52" lower bar
- "Gear Cave" preserves roughly 40 cu ft of usable bed space
- Clamp-on install with no drilling required
- Tonneau cover compatibility (rules vary by cover), with mounting kits available
- Backed by a 3-year limited warranty
Fitment runs by bed size, not year, make, or model: the Base Rack fits 4'10" through 8' beds with inside widths of 40–64", a range that spans most compact through full-size trucks.

Chase Rack System FAQs
What truck beds does the Chase Rack System Base Rack fit?
Fitment runs by bed size rather than year, make, or model. The Base Rack fits beds from 4'10" to 8' long with inside widths of 40–64", a range that spans most compact, mid-size, and full-size pickups. Measure your bed's length and inside width, then match those numbers against the rack's fitment range before ordering.
How much weight can the Base Rack carry?
Big Days rates the Base Rack for up to 900 lbs of load, and the rack itself weighs 70 lbs. That capacity rides on 3/16" A36 steel risers and 6560 T6 alloy cross bars, while the "Gear Cave" underneath preserves roughly 40 cubic feet of usable bed space for coolers, fuel, and gear.
What's the difference between the Base Rack and the Starter, Essential, Pro, and Elite builds?
The Base Rack is the bare platform: risers, cross bars, T-track, and clamp hardware with no mounts. Starter, Essential, Pro, and Elite builds bundle that same rack with progressively larger loadouts of moto mounts, bike trays, and accessories — pick a build if you know your haul, or start here and configure piece by piece.
