Yukon Gear Dura Grip For GM 12 Bolt Cars w/ 33 Spline Axles

This is the Yukon Gear Dura Grip differential case, a well-built component for GM 12-bolt rear ends found in a variety of classic passenger cars. If you're rebuilding your differential and need a solid case for your 4.10 or higher gear ratio setup, this is a popular choice. It's designed for 33-spline axles, ensuring a strong connection to your drivetrain.

Crafted from high-strength nodular iron, this case is precision machined for a precise fit. It comes bare, meaning you'll need to supply your own spider gears, clutches, and springs to complete the assembly. This allows you to customize the differential's performance to your specific needs, whether you're aiming for improved traction for spirited driving or a more robust setup for general use. The nodular iron construction offers good durability for its intended applications.

This case is a direct fit for many GM 12-bolt applications, including models like the Chevrolet Impala, Pontiac GTO, and Buick Wildcat from the mid-60s through the early-70s. Make sure to verify your specific vehicle's rear end and axle spline count before ordering.
