There’s no modern muscle car more popular than the 5th Generation Chevrolet Camaro. Today’s Camaros are the perfect platform to go faster and build insane amounts of horsepower, that is except for the factory independent rear suspension (IRS). The factory rear housing is the car’s weakest link and that is why HammerHead has created the new standard in high horsepower independent rear suspension technology: the revolutionary HammerHead 12-bolt housing.The HammerHead housing is part of three different complete bolt-in replacement kits for the 5th Generation (2010+) Camaro. HammerHead housings has teamed up with industry leader The Driveshaft Shop and will offer kits featuring race proven DSS axles rated up to 1400HP as well as their bulletproof driveshafts. The HammerHead 12-bolt housing features more strength and less horsepower loss than a 9-inch Ford housing. And by using a 12-bolt, the HammerHead allows a larger selection of gear ratios, posi units, and racing spools when compared to OEM style differential options.
The HammerHead 12-bolt housing comes standard in lightweight cast aluminum but is also available in nodular iron for extreme performance usage. Kits are available in three stages; from bulletproof to indestructible, and the HammerHead has been prototype tested on the racetrack and over 2000 miles of street use in a 900-plus-horsepower Camaro with a 35-spline WaveTrac posi unit. Best of all, the HammerHead kit is an easy bolt-in installation, and is available with an optional carbon fiber driveshaft or WaveTrac 35-spline posi unit.
The HammerHead is already raking in awards including a nomination into the Foundrymen’s Society Casting of The Year Competition. The annual casting competition showcases excellence in design, engineering and metalcasting.
