The Hot Rod HammerHead is our universal housing with multiple mounting points for custom Hot Rod, Pro Touring, Kit Car or Race Car builders who want to make the move to Independent Rear Suspension. With a A206-T4 cast aluminum housing 32% stronger than standard A356-T6 aluminum, further reinforced by increased wall thickness at key OEM failure points, our Hot Rod Hammerhead provides the strength and capability for those who strive to reach up to 1000 horsepower and is the ultimate stock replacement differential housing for C2 & C3 Corvettes as well as 1999-2004 Ford Mustang Cobra IRS. It is also the perfect Independent Rear Suspension solution for more exotic applications like Cobra kit cars, 4WD/AWD projects and virtually any custom application your fabricator can build an IRS cradle for.
