GRIP PRO-GM 7.75 IRS

The Powertrax Lock-Right Locker is an automatic locking differential designed for extreme traction, durability, and strength. It installs easily in existing case assemblies, typically without special tools or setup equipment, often in under two hours. The Lock-Right enhances the strength of the surrounding original case and driveline components by eliminating wheel spin-up. It operates by sending engine power to the wheels with the most traction, locking axles together when traveling straight, and allowing the outside wheel to rotate faster in turns through an overrunning mechanism. This provides 100% traction on-demand in challenging conditions like snow, sand, mud, and ice. The Grip Pro series offers smooth, dependable torque transfer and traction.
