Eaton Detroit Locker Differential 31 Spline 1.32in Axle Shaft Diameter 3.25 & Up Ratio Rear 9in

The Detroit Locker differential uses a unique, bullet-proof design that locks both wheels together 100% automatically, ensuring maximum traction even if one wheel loses contact with the ground. This is a serious upgrade for vehicles needing ultimate grip, working reliably in both forward and reverse directions. It's a maintenance-free part that keeps both wheels driving, no matter what the road or trail throws at you.

Built with strength in mind, this locker is designed for 31-spline axles with a 1.32-inch shaft diameter and is compatible with 3.25 and numerically higher gear ratios in a 9-inch rear end. Its clutchless design means there are no wear parts to worry about, making it a solid, long-lasting choice for a wide range of Ford vehicles, from classic Broncos and Econolines to Aerostars and more. This differential is a popular choice for those looking to improve off-road capability or towing stability.

When installing this differential, it's important to ensure your 9-inch rear end is in good condition and that you have the correct gear set for your application. Refer to the manufacturer's installation instructions for specific details regarding setup and any required additional components to ensure optimal performance and longevity.
