Yukon Gear Duragrip Posi For 63-79 Ci Corvette w/ 17 Spline Axles / 2.73-3.90 Ratios

If you're looking to get the most out of your classic 1963-1979 Chevrolet Corvette, especially when it comes to putting power down through the rear wheels, a limited-slip differential is a significant upgrade. This Yukon Dura Grip unit is designed specifically for your Corvette, ensuring that both rear wheels receive power when you need it, improving traction whether you're accelerating out of a corner or just driving on varied road surfaces. It's built to handle the demands of a performance-oriented vehicle like yours.

Yukon Gear & Axle builds the Dura Grip with serious durability in mind. It features a strong nodular case and forged 4320 chromoly spider gears, which are cut to provide the strongest possible teeth. The composite clutches are key to its operation, providing smooth engagement for everyday driving while still delivering aggressive traction when you push the car. This unit is also fully rebuildable, meaning it's designed for a long service life and can be refreshed down the road if needed. It's assembled in the USA, reflecting a commitment to quality construction.

This particular Dura Grip is set up for Corvettes with 17-spline axles and is compatible with 2.73 to 3.90 gear ratios, including thicker gear sets. When installing a new differential, it's always a good idea to replace your gear oil and potentially other related components like axle bearings and seals to ensure everything works together smoothly and lasts as long as possible. Refer to the manufacturer's installation instructions for specific details.
