HammerHead® Housings are American designed, engineered, and manufactured race and award winning differential housings. All of our differentials are engineered for strength and cast in A206-T4 aluminum, 30% stronger than the more popular A-356 Aluminum. We have three different HammerHead® housings designed to take 12 bolt GM, 8.8 Ford, or Ford 9.75″ Gears and have been proven capable of handling in excess of 1000 horsepower. We have engineered multiple bolt in kits for popular IRS performance vehicles like C2-C4 Corvette, Gen 1&2 Viper, 5th Gen Camaro, Mustang Cobra, and have applications in the pipeline for Dodge/SRT Hellcats. We also sell HammerHead® differential housings to professional chassis and car builders who work on custom projects or manufacture kit cars.
