Secure extra power for your 5th Gen 4Runner with this passenger-side spare battery tray. Weighing just 7 lbs, it’s built to hold an auxiliary battery up to 11″ long, 7″ wide, and 9″ tall, perfect for powering lights, accessories, and other gear. Unless you select the powder-coated option, the tray must be painted or coated before installation to prevent rust.
