Description

The Zumbrota Drivetrain BK GMHO72-A is a bearing installation kit specifically designed for GM HO72 differentials that do not utilize a load bolt and feature a ball bearing design. This kit is an ideal solution for professional shops and builders who have a surplus of shims and are looking for a more cost-effective option compared to a full Master Overhaul kit. This installation kit includes essential components for a proper differential service. It features premium Timken bearings and races for both the carrier and pinion, ensuring durability and performance. Additionally, the kit comes with a pinion seal, and if applicable to the specific application, a crush sleeve, oil baffles, and slingers. It also includes marking compound and a brush for accurate setup. Yukon, the manufacturer, conducts thorough research for each application to guarantee that the kit contains all the necessary parts for a successful ring and pinion installation.
