Yukon Gear Trac Loc For Ford 9in With 28 Spline Axles. Aggressive Design

If you're looking to improve traction for your Ford 9-inch rear end, especially when you're heading off-road or need better grip during spirited driving, this Yukon Gear Trac Loc limited slip differential is a solid choice. It's designed to work with 28-spline axles and fits a wide range of classic Ford vehicles, including models like the Bronco, F-150, and Mustang, across many years of production. This unit replaces your open differential, sending power to both rear wheels when needed, which significantly improves grip in slippery conditions or during aggressive maneuvers.

Yukon builds this Trac Loc with performance and durability in mind. It features a strong nodular iron case and forged 4320 chromoly spider gears, which are known for their toughness. The differential also uses composite clutches and an aggressive 4-pinion design with 4 preload springs, all assembled in the USA. This combination offers smooth engagement for everyday driving but can deliver aggressive traction when you demand it. Plus, it's fully rebuildable, meaning you can service it down the road to keep it performing at its best.

This Trac Loc is specifically designed for the Ford 9-inch axle with 28-spline axles and works with all gear ratios. Keep in mind that this is an aggressive unit, and some chatter may be present during normal driving, which is typical for this type of performance differential. You will also need to use Trac Loc bolts for installation.
