Yukon Gear Trac-Loc For Ford 8in w/ 28 Spline Axles. Aggressive Design

If you're looking to improve traction for your classic Ford or Mercury vehicle, especially when heading off-road or into challenging conditions, a limited-slip differential like this Yukon Trac-Loc is a smart upgrade. This unit is designed for the Ford 8-inch rear axle with 28-spline axles, fitting a wide range of popular vehicles from the 1960s and 70s, including models like the Ford Mustang, Mercury Cougar, and Ford Bronco. It replaces your open differential to send power to both rear wheels, significantly improving grip when one wheel starts to lose traction.

This Trac-Loc features an aggressive design with four preload springs and a four-pinion gear setup, built for serious performance. The spider gears are forged from 4320 chromoly for exceptional strength and durability, and the composite clutches are chosen for smooth engagement that still provides aggressive traction. The case is made from a high-strength nodular iron, ensuring it can handle the demands of spirited driving and varied terrain. Plus, it's completely rebuildable, meaning you can service it down the road to keep it performing at its best. This unit is assembled in the USA and has undergone extensive product testing.

When installing this differential, be aware that it's designed for racing applications and may chatter during normal street driving, as noted by the manufacturer. You'll also need to ensure you have the correct Trac-Loc bolts. This is a substantial upgrade for your drivetrain, offering a significant improvement in traction for a variety of classic Ford and Mercury applications.
