Duragrip Differential GM 12 Bolt Car 30 Spl HD

The Duragrip Differential GM 12 Bolt Car 30 Spl HD is a high-performance upgrade designed for automotive enthusiasts and mechanics looking to enhance traction and durability in classic muscle cars and street performance builds. This differential is engineered to replace the factory unit in GM 12-bolt rear axles, addressing the weaknesses of original equipment while ensuring compatibility with OEM bolt patterns.

Featuring a robust locking differential design, the Duragrip provides consistent power delivery to both rear wheels during acceleration, effectively eliminating the wheel-spin disadvantage of open differentials. Its heavy-duty construction and precision-machined components are built to withstand elevated torque loads, making it suitable for both street and strip applications. The 30-spline shaft specification ensures compatibility with modern horsepower levels while maintaining backward compatibility with standard 12-bolt housing geometry.

Ideal for those restoring vintage Chevelles, Camaros, or Novas, the Duragrip Differential is designed for straightforward installation by experienced mechanics with access to a lift and basic axle-work tools. Yukon Gear and Axle's commitment to quality ensures tight tolerances and quality control throughout the assembly process, reducing noise and vibration often associated with inferior aftermarket alternatives.
