Corvette Road Upgrade Parts

This is what the condition is in your differential, your axle yoke is riding on a 3/4" spider gear shaft

The bottom axle yoke is what it looks like as installed new, the top one shows after it has been run a while, note the difference in the 2 from the "C" clip groove to the end of the splines, before long the one on the top will be worn away to the point of letting the "C" clip fall off and enter your gears, very bad.

CORVETTE ROAD Axle Yoke Load Block pictured, the stock setup is the yoke riding directly on the spider gear shaft which literally grinds the end off the axle yoke, the result is the wheels tipping in at the top and loss of the struts ability to remedy the condition. This upgrade allows the axle yoke to ride on the polished flat surface of the block eliminating the damage to the axle yoke. Grooves cut into the end of the axle yoke allow lubricant onto the contact surfaces. The CORVETTE ROAD kit includes the Axle Yoke Load Block and the replacement axle yokes that are designed to work with the axle block.
