Eaton Detroit Locker Differential 28 Spline 1.20in Axle Shaft Dia 2.73-5.13 Ratio Front/Rear 8.5in

When you're looking to get the most out of your drivetrain, the Eaton Detroit Locker differential is a solid choice. What you get in this package is the Detroit Locker unit itself, designed to provide 100% automatic locking for maximum traction. This isn't a part that requires any special engagement; it works automatically in both forward and reverse, ensuring both wheels are driven even if one loses contact with the ground. It's built for a wide variety of vehicles, including many Buick, Cadillac, and Chevrolet models, and is compatible with axle shaft diameters of 1.20 inches and gear ratios from 2.73 up to 5.13 on 8.5-inch ring gear axles.

The strength of the Detroit Locker comes from its unique, bullet-proof design. It's a clutchless, maintenance-free unit, meaning fewer parts to worry about and less upkeep down the road. This design ensures that both wheels are always locked together, delivering consistent power to the pavement or trail. This is a serious upgrade for anyone needing reliable traction in challenging conditions, whether you're off-roading, towing, or just want the confidence of knowing your vehicle will keep moving forward.

Installing a locker like this is a significant drivetrain modification. It's important to ensure your axle housing is the correct 8.5-inch size and that your axle shafts are 28-spline with a 1.20-inch diameter. Because this differential locks both wheels together, it will affect on-road handling, particularly during turns, so it's best suited for vehicles where maximum traction is the priority.
