Yukon Gear Positraction internals For GM Ci Corvette w/ 17 Spline Axles

When you're rebuilding the differential in your 1963-1979 Chevrolet Corvette, this Yukon Gear & Axle Positraction spider gear kit gives you all the internal components you need. This kit is designed to replace the spider gears, side gears, and related hardware within your Positraction differential, ensuring smooth power delivery to both rear wheels.

Yukon uses higher quality materials and manufacturing techniques than what you'd find in OEM parts. This means the spider gear set is built to last longer and handle the stresses of daily driving and spirited runs. The kit includes two side gears, four pinion gears, the cross pin shaft, a roll pin, and the necessary spider gear thrust washers, providing a complete set for a proper replacement.

This kit is specifically for Corvettes equipped with the Dura Grip Positraction differential and 17-spline axles. It's important to note that this kit does not include clutches, so if your existing Positraction unit requires clutch replacement, you'll need to source those separately.
