Description

The Yukon '99-'04 Mustang Axle kit by Yukon Gear and Axle is a comprehensive upgrade for your 1999-2004 Ford Mustang's differential. This kit is engineered for the Ford 8.8" axle and features 31 spline axles with a 5-lug configuration, ensuring robust performance and compatibility. Included in this kit is the Dura Grip Positraction unit, which enhances traction and handling, especially during spirited driving or under acceleration. Alongside the positraction unit, you'll find all necessary components for a complete installation, including carrier bearings and races, carrier shims for proper gear setup, axle bearings and seals to protect against contaminants, and studs for secure mounting. This all-in-one solution simplifies the upgrade process for your Mustang's rear end. This axle kit is specifically designed for 1999, 2000, 2001, 2002, 2003, and 2004 Ford Mustang models equipped with the 8.8" differential. It offers a direct fit, providing a significant improvement in drivetrain strength and performance.
