Our CNC machined aluminum battery mount is designed around the optima battery. It is a simple, strong, and good looking way to hold your Optima battery anywhere. The entire battery mount is machined from 6061 billet aluminum. This kit is designed to relocate the battery in the trunk of your vehicle. It will not fit in the vehicle's factory battery location. Three countersunk stainless steel bolts secure the bottom of the battery mount to the support rods while we provide 6 mounting holes to give you added flexibility. The dimensions of the battery mount are 11 1/2" X 8 1/2" X 7 1/2" tall.
