The Big Days Bolt On Clamp Kit is the hardware that turns your Chase Rack System into a permanent fixture. Instead of clamping to the bed rail, this kit bolts the rack straight through your truck bed's side rails — the method Big Days calls its most secure mounting option. It's the right choice if your rack lives on one truck and you'd rather trade quick removal for maximum hold while hauling dirt bikes, mountain bikes, and gear down rough roads.
Features
- Bolt-on mounting hardware for the Big Days Chase Rack System
- Anchors the rack directly through the truck bed side rails
- Big Days' most secure, permanent mounting method
- 10–15 minute install after drilling four 3/8 in. holes
- Part of the Big Days Small Parts line for repairs and mount swaps
Like the rack itself, fitment runs by truck bed size rather than year, make, and model, so this kit applies across the bed sizes the Chase Rack System supports. Want to keep the rack removable instead? The Standard Clamp Kit clamps to the bed rail and stays removable, and the Deck Rail Clamp Kit is the option for beds with factory deck rails. Find the rest of the hardware in our rack accessories collection.
Small Parts FAQs
Which racks does the Bolt On Clamp Kit work with?
It's mounting hardware for the Big Days Chase Rack System, replacing the standard bed clamps with a bolted connection through the truck bed side rails. Because Big Days racks fit by bed size rather than year, make, and model, the kit applies across the bed sizes the rack itself supports.
Do I have to drill my truck bed to install it?
Yes. Big Days' bolt-on method requires drilling four 3/8-inch holes through the bed side rails, then bolting the rack in place. The company estimates 10 to 15 minutes for the install, and calls the result its most secure, permanent mounting option.
Should I choose the bolt-on kit or the standard clamps?
Go bolt-on if the rack stays on one truck permanently — Big Days calls it the most secure mounting option, at the cost of drilling four holes. The standard clamps keep the rack removable, so you can pull it off or move it to another truck without leaving holes behind.
