Barnes 4wd
1/2 ton status
The Barnes 4WD Optima Battery Box is cut from 1/8” steel and formed for a very snug fit around your common 34/78 Optima battery size to prevent any movement. This battery box was designed to give you the most mounting options possible. Each Battery box kit comes with the coated 5/16” hardware as well as lock nuts to prevent your fasteners from coming loose or corroding.
