Increase underhood room and improve handling on your Third and Fourth Gen GM F-Body with a Battery Relocation Kit from BMR Suspension. This custom battery box mounts to the rear frame rail in place of the OE spare tire. This allows you to remove weight from the nose of your car and put it where it needs to be over the rear wheels. The kit is designed from CNC-laser cut and formed steel plate. The kit comes complete and requires no cutting or fabrication to install.
