Description

The Zumbrota Drivetrain YGK2040 is a comprehensive differential gear kit engineered to streamline your re-gear project. This kit consolidates essential components, including front and rear Yukon ring and pinion gear sets and a Yukon Master Overhaul Kit, all under a single part number. Yukon Gear & Axle is recognized for its high-performance ring and pinion sets, developed with state-of-the-art design, advanced heat-treating, and rigorous quality control to meet exacting specifications. This kit is specifically designed for applications featuring a 10-bolt rear cover and a 10-bolt ring gear, with an 8.8" ring gear diameter and a 4.11 gear ratio. It includes a Yukon Dura Grip clutch-style limited-slip differential for enhanced traction and is equipped with 2.53" axle bearings and seals, along with a 3.250" inner pinion bearing outside diameter. These kits are ideal for increasing tire size, improving towing capacity, or enhancing off-road performance. This ensures that vehicles can be quickly returned to the road. The inclusion of the Yukon Dura Grip Limited Slip Differential means you get a fully rebuildable positraction unit. This kit is generally compatible with Ford Bronco (1983-1996) and Ford E-150 (2003-2006) models, among others for 8.8" differentials.
