Description

The USA Standard Pinion installation kit is a comprehensive solution for the installation or replacement of pinion components in GM differentials. Designed for models from 2000 and up, this kit specifically fits GM 7.5" and 7.625" axle sizes. It ensures that you have all the necessary parts for a proper and reliable installation. The included components are crucial for the correct setup of the pinion assembly, comprising pinion bearings and races, a new pinion seal to prevent leaks, a pinion nut for securing the bearing preload, a crush sleeve for establishing the correct bearing preload, and marking compound with a brush for precise pattern setup. This ensures that all parts are included for a successful rebuild or installation.
