These Truck Bed Risers convert the TrailHead Hitch Rack — the hitch-mounted rack Big Days sold in its Boundry days — into a truck bed rack. The riser attachments carry your existing rack above the bed rails instead of off the receiver, which puts bikes up and out of the way and hands the hitch back to a trailer. If you bought a TrailHead and later found yourself wanting bed-mounted hauling, this is the set that gets you there without starting over.
Features
- Converts the Boundry-era TrailHead Hitch Rack into a truck bed rack
- Set of riser attachments that support the rack above the bed rails
- Frees your hitch receiver for a trailer or other gear
- From Big Days (formerly Boundry), the chase rack company in Orem, Utah
- Part of the Big Days Small Parts line
As with everything Big Days builds, bed-rack fitment runs by truck bed size, not year, make, and model. For reference, the current Chase Rack System platform lists fitment for beds 4'10" and longer with 40–64 inch inside dimensions, with mounting hardware that ranges from clamp kits to drilled bolt-on options like the Bolt On Clamp Kit. Measure your bed and confirm your TrailHead configuration before ordering. Starting fresh instead of converting? A complete chase rack build is the cleaner path.
Small Parts FAQs
Which rack do these risers convert?
They're built for the TrailHead Hitch Rack sold under Boundry — the company that later rebranded as Big Days. The riser attachments take that hitch-mounted rack and turn it into a truck bed rack. If you don't own a TrailHead, start with a complete Chase Rack System build instead.
Will the converted rack fit my truck bed?
It depends on your bed's size — Big Days fits its racks by bed dimensions, not year, make, and model. For reference, the current Chase Rack System lists fitment for beds 4'10" and longer with 40 to 64 inch inside measurements. Measure your bed and confirm your TrailHead configuration before ordering the risers.
What's involved in the conversion?
The riser attachments support your existing rack above the truck bed instead of in the hitch receiver. Big Days doesn't publish detailed specs for this kit, so confirm hardware questions with the company before ordering — and if you'd rather skip the wrenching, Big Days runs an install bay at its Orem, Utah headquarters.
