Bed cargo has a way of migrating to the tailgate by the end of a washboard road. The Big Days Storage Case/Cooler Mount fixes that: two L-shaped brackets that work with the rack system's lower bar to hold storage boxes and coolers in place in the bed of your truck. Set the brackets against your case, tighten the T-Track hardware, and the box stays put — through the whoops, up the shuttle road, and back.
Features
- Two L-shaped brackets hold storage boxes and coolers in place in the truck bed
- Works with the Big Days lower bar
- All necessary T-Track hardware included
- T-Track mounting lets you position each bracket to match your container
- No drilling — everything anchors to the bar
These brackets require a Big Days lower bar. If your Chase Rack build didn't include one — or you want a bar dedicated to cargo duty — add the Small Parts Lower Beam. Worth knowing before you double up: the In-Bed Moto Ramp already comes with storage mounting brackets included. Browse the rest of the system in our Big Days truck accessories collection.
Storage Case/Cooler Mount FAQs
What do I need for these brackets to work?
A Big Days lower bar. The two L-shaped brackets attach to the lower bar with the included T-Track hardware and hold storage boxes and coolers in place in the bed. If your Chase Rack build didn't include a lower bar, add the Small Parts Lower Beam and you're set.
Will the brackets fit my specific cooler or storage box?
Flexible by design. The brackets position along the lower bar via the included T-Track hardware, so you set the spacing to match your container's footprint. Big Days doesn't publish a maximum case size — the practical constraints are your bed space and where the lower bar sits in it.
How do the brackets install?
Installation uses the included T-Track hardware — no drilling. Place your storage box or cooler in the bed, set the L-brackets against it on the lower bar, and tighten everything down. Because the mount lives on the bar's track, you can reposition the brackets whenever your load changes.
