Eaton Detroit Locker Differential 35 Spline 1.50in Axle Shaft Diameter 4.56 & Up Ratio Rear Dana 70

What you're getting here is the Eaton Detroit Locker, a well-known automatic locking differential designed for serious traction. This unit is built to keep both rear wheels driving, even if one tire loses contact with the ground. It's a clutchless design, meaning there are no friction plates to wear out, and it works reliably in both forward and reverse. This differential is a popular choice for vehicles that see heavy use, from off-roading to towing, where consistent grip is essential.

The Detroit Locker is a robust piece of hardware. It features a unique, strong design that ensures both wheels are locked together under power, delivering 100% of available torque to both sides. This means you get maximum traction without needing to do anything – it's fully automatic. The maintenance-free aspect is a big plus; once installed, it's built to last without requiring regular adjustments or fluid changes related to clutch packs. This particular model is set up for Dana 70 rear axles, specifically for vehicles with 35-spline axle shafts and a ring and pinion gear ratio of 4.56 or numerically lower (like 4.10, 3.73, etc.).

This differential fits a wide range of vehicles, including many Chevrolet Astro and G-series vans from the 80s, as well as various Dodge trucks and vans from the 70s and 80s. It's a solid option if you're looking to significantly improve your vehicle's ability to get moving in slippery conditions or on challenging terrain. Remember to check the specific fitment details to ensure it matches your axle and gear ratio requirements.
