Battery Box S/S Dropout

The Battery Box S/S Dropout from Allstar Performance is a stainless steel battery mounting solution engineered for drag racing, circle track, and high-performance street rod applications. This dropout-style enclosure secures auxiliary batteries in tight engine compartments where space is at a premium and vibration resistance is non-negotiable. Built for serious enthusiasts who run dual-battery systems or relocate power sources away from stock locations, this component eliminates parasitic loads and improves weight distribution for better front-end grip during launches.

Constructed from stainless steel, the Battery Box S/S Dropout resists corrosion, salt spray, and thermal cycling—critical factors in performance vehicles exposed to track conditions or storage in harsh environments. The dropout design allows quick battery access and removal without permanent installation fasteners, making it ideal for competitors who swap batteries between events or perform routine maintenance. At 8.9 pounds with compact external dimensions of 10.4 x 8.6 x 13.2 inches, this box provides secure containment while maintaining the weight savings essential to competitive racing builds. The welded stainless construction ensures structural rigidity under acceleration loads and prolonged vibration exposure.

Mechanics and fabricators favor the Allstar Performance Battery Box S/S Dropout for custom engine bay layouts, fuel cell relocations, and secondary electrical system installations on vehicles with power steering pumps, alternators, or onboard air systems drawing from auxiliary batteries. Installation requires basic welding or bolt-down mounting to frame rails, making it compatible with tube chassis, unibody reinforcement, and modular frame designs. Whether you're building a vintage hot rod, a modern bracket racer, or a road course competitor, this dropout box delivers reliability and corrosion immunity in one compact package.
