Description

The Zumbrota Drivetrain YGK2037 is a comprehensive differential re-gear kit, combining Yukon Gear & Axle's high-performance ring and pinion gear sets with a complete Yukon Master Overhaul Kit. This all-in-one package simplifies the process of rebuilding your differential, whether you're looking to increase tire size, improve towing power, enhance off-road capabilities, or replace worn gears. This kit features an 8.8" Ford 3.31 rear ring and pinion gear set, designed to meet exacting specifications through advanced heat-treating and quality testing. It includes Yukon Dura Grip clutch-style limited-slip differential (LSD) components for improved traction, along with axle bearings and seals. The inner pinion bearing has a 3.250" outside diameter, and the kit is specifically for applications requiring a 10-bolt rear cover and a 10-bolt ring gear. Yukon Pro Kits, like the YGK2037, are engineered for quality and backed by a strong warranty.
