Description

The USA Standard Gear rear axle kit is a direct replacement for GM 55-56 passenger car rear differentials. Each kit includes everything needed to replace, repair, or upgrade your axle shafts, getting your vehicle back on the road quickly. This specific kit is for the right-hand side, featuring 17 splines, a 30-3/16 inch length, and a 1.200 inch bearing offset. The kit contains the axle shaft, wheel bearing, axle seal, studs, and lug nuts. USA Standard Gear replacement axles are constructed to meet or exceed original equipment (OE) quality standards. The use of advanced alloys and the latest heat-treating technologies results in a strong and durable axle shaft.
