The W.O.D. Optima Battery Box Mounting Bracket is a heavy-duty battery tray designed around the popular Optima battery platform. Engineered to fit Group 34/78 batteries, it also accommodates many other batteries with similar dimensions. Whether you're building a rock crawler, Ultra4 race car, buggy, Jeep, race truck, or custom fabrication project, this battery mount delivers the strength and versatility serious builders demand. Designed for universal vehicle fitment, this battery box can be mounted from the bottom or rear, giving builders greater flexibility when packaging tight engine bays, rear chassis sections, cargo areas, or custom tube chassis layouts. When paired with the W.O.D. Battery Box Hanger (P/N WA01061H), it can be mounted directly to chassis tubing, making it an ideal solution for tube-frame vehicles and one-off builds.

Can the battery box be painted or powder coated? Yes. The battery box ships raw so it can be painted, powder coated, or otherwise finished to match your chassis, suspension, or overall vehicle color scheme.
