Moroso Battery Box
Moroso Sealed Battery Boxes: Built for the Track, Ready for the Street
When it comes to battery relocation, few names carry the credibility of Moroso Performance Products. Founded in 1968 and still family-owned and operated, Moroso has spent decades engineering parts that meet the demands of serious racers and performance enthusiasts alike. Their battery boxes are a prime example of that philosophy — purpose-built, sanctioning-body approved, and packed with everything needed for a clean, safe installation.
Why Battery Relocation Matters
Moving a battery from the engine bay to the trunk or rear of a vehicle isn't just a custom touch — it's a practical performance upgrade. Rear battery placement improves front-to-rear weight distribution, frees up valuable underhood space, and can be a requirement for vehicles competing under NHRA, IHRA, or SCCA rulebooks. Doing it right means containing potential battery gasses, securing the battery against movement, and routing cables safely through the chassis.
What Sets the Moroso Sealed Battery Box Apart
The Moroso Sealed Battery Box is ideal for relocating a battery to the rear of any race, street, or show vehicle with or without a rear firewall. That last detail matters: this completely sealed, externally vented design makes it ideal for hatchbacks and other applications without a rear firewall.
Accepted by the NHRA and IHRA, these tough polyethylene boxes have an airtight lid with a foam gasket to keep battery gasses from entering your car's interior, with six quick-release fasteners keeping the lid on tight. The non-conductive polyethylene construction is also a safety advantage — it is a very safe battery box compared to aluminum/steel and homemade battery boxes that are conductive.
The box is fully approved for racing by NHRA, IHRA, and SCCA, and accommodates a wide range of battery series — including Series 21, 24, 26, 34, 42, 54, 55, 56, 61, 62, 63, 85, 86, and 96R — with either top-post or side-post terminals.
Complete Hardware Included
Moroso doesn't leave you sourcing hardware elsewhere. These boxes come with a vent tube, a battery hold-down with 3/8 in. steel rods, rubber cable clamps and grommets, and mounting hardware. The result is a straightforward installation that doesn't require improvising or making multiple trips to the hardware store. For those who also need to run new wiring, Moroso offers a complementary Battery Cable Kit (No. 74055) designed to work alongside the box.
Trusted Since 1968
Moroso Performance and its family of companies have been family owned and operated for almost sixty years across three generations, with the goal of producing the best quality and continually innovating — manufacturing products right here in Connecticut, USA since 1968. That heritage of American craftsmanship and racing DNA is exactly why the Moroso battery box remains a go-to solution for bracket racers, road racers, and show car builders alike.
