Eaton Detroit Locker Differential 35 Spline 1.50in Axle Shaft Diameter 4.10 & Down Ratio Dana 60HD

Starting with its 35-spline, 1.50-inch axle shaft diameter design, the Eaton Detroit Locker is built for serious traction. This automatic locking differential is a popular choice for vehicles needing maximum grip, whether you're navigating tough off-road trails or dealing with slippery conditions. It's engineered to keep both wheels turning, even when one loses contact with the ground, ensuring you maintain forward momentum. This robust design works reliably in both forward and reverse gears.

The Detroit Locker is a clutchless design, meaning it requires no special maintenance beyond standard gear oil changes. Its strength comes from a unique, bullet-proof mechanism that automatically locks the two axle shafts together when torque is applied. This 100% automatic engagement means you don't need to do anything; the locker engages when you need it and disengages as you turn, allowing for reasonable steering control on pavement. It's designed for axles with a 4.10 or lower (numerically higher) gear ratio, specifically for Dana 60HD and Dana 60 applications.

This differential is a solid option for a wide range of trucks and vans, including models like the Ford Aerostar, Dodge Ram 2500, and Chevrolet Astro. If you're looking to significantly improve your vehicle's traction in challenging situations, the Detroit Locker offers a maintenance-free and strong solution. It's a well-known component for those who push their vehicles beyond typical road use.
