Yukon Gear Dura Grip Positraction For GM 12 Bolt Car w/ 30 Spline Axles / 3.73+

Built with forged 4320 chromoly spider gears, this Yukon Dura Grip positraction differential is designed for serious traction and durability. It's a limited-slip unit that uses composite clutches to smoothly transfer power to both wheels, giving you more confidence and control whether you're on the street or tackling rougher terrain. This unit is specifically made for GM 12-bolt car differentials with 30-spline axles and is intended for vehicles with a 3.73 or numerically lower gear ratio.

The Dura Grip is fully rebuildable, meaning you can service it down the road to keep it performing at its best. The nodular case is well-built for strength, and the composite clutches offer a comfortable engagement that won't be jarring during normal driving. Yukon Gear & Axle backs this unit with extensive product testing, and it's proudly assembled in the USA, ensuring a high standard of quality.

This differential fits a wide range of GM vehicles, including models like the Chevrolet K10 Pickup from 1963-1974 and the GMC C1500 Pickup from 1979-1986. If you're looking to improve your vehicle's ability to put power down, especially when traction is uneven, this positraction unit is a solid choice.
