Description

The Zumbrota Drivetrain Rear Axle Kit, also known as the USA Standard Gear ZA K630324, is engineered for GM 8.6-inch differentials. Constructed with advanced alloys and subjected to the latest heat-treating technologies, this axle is built for strength and durability, meeting or exceeding original equipment (OE) quality standards. The kit includes a 34.25-inch long axle shaft with 30 splines, specifically for rear applications with 6 lugs, and it is designed to fit either side of the differential.
