$60.00
Secure your Optima battery with confidence using our Optima D34/78 Battery Box, designed for off-road, race, and custom vehicle builds. This heavy-duty steel battery mount is made from 1/8″ steel and is laser cut and CNC formed in-house in the USA for precision, strength, and durability.
Our battery tray gives you the flexibility to weld it in or bolt it down. We’ve added 1/4″ holes in the base that align with the cavities on the bottom of the Optima D34/78 battery. This provides clearance for bolt heads and allows for a clean bolt-in installation if desired.
In addition, whether you’re rock crawling, racing, or building a custom rig, this box holds your battery securely in place. Plus, the included top clamp keeps your battery locked down during extreme use. We provide five flanged 1/4″ bolts with nylock nuts to secure the clamp plate.
