Description
Installing a quality bearing kit is essential when you’re rebuilding or upgrading your 8.875-inch GM 12-bolt rear axle—it ensures proper pinion depth, carrier preload, and gear mesh geometry that directly impact durability and performance. This Allstar Performance kit eliminates the guesswork by bundling every component you need for a complete, professional-grade assembly, whether you’re setting up a street machine or a dedicated track car. Skip the headache of sourcing individual bearings, shims, and seals separately and get back to turning wrenches with confidence.
