Description

Constructed with high-strength 9310 steel gears and a robust case-hardened steel body, this unit ensures durability and performance under demanding driving conditions. Designed as a direct fit for a range of GM vehicles, the Wavetrac differential is compatible with the Pontiac GTO from 2004-2006 and Holden VZ models. It also fits the Pontiac G8 (2008-2009), Holden VE Commodore, and Chevrolet SS models from 2014 onwards. Please note that this differential does not include a ring and pinion set. This Wavetrac unit utilizes a patented design to actively bias torque to the wheel with more grip, enhancing stability and control whether you're on the street or the track.
