Description

The Yukon Gear Kit YGK2139 is a comprehensive solution for re-gearing your vehicle's differential. This kit combines high-performance Yukon Ring & Pinion gear sets with Yukon Master Overhaul Kits into a single part number, streamlining your re-gear project. It is designed for applications with a 12-bolt rear cover and a 12-bolt ring gear. This kit includes a 10.5" Ford ring gear with a 3.73 gear ratio and 35 spline count, specifically configured for Posi (limited-slip) differentials. The included Yukon Dura Grip clutch-style limited-slip differential is fully rebuildable. Yukon engineers utilize advanced design, heat-treating, and quality testing processes to ensure their ring and pinion gear sets meet exacting specifications and industry standards. This YGK2139 kit is ideal for those looking to increase tire size, enhance towing capacity, improve off-road performance, or replace worn differential gears. By bundling the necessary components, Yukon aims to save you time and money compared to purchasing parts individually. The kit also comes with specific inner pinion bearings and races (NP 504493/ NP 949481).
