When you're looking to get the most traction out of your rear end, the Eaton Detroit Locker is a solid choice. This is a 100% automatic locking differential, meaning it engages without any input from you. It's designed to keep both rear wheels turning together, even if one loses contact with the ground, which is crucial for getting moving in slippery conditions or when you're tackling tough terrain. This unit is built for an 8.75-inch ring gear and works with axle shafts that are 30-spline and 1.28 inches in diameter, and it's compatible with gear ratios from 2.76 up to 4.56.

What makes the Detroit Locker stand out is its unique, robust design. It's a clutchless system, which means there are no wear parts like clutches or bands to worry about, making it maintenance-free and incredibly strong. This differential locks up 100% of the time in both forward and reverse, ensuring consistent power delivery to both wheels. It's a popular upgrade for a wide variety of vehicles, from classic Chrysler and Dodge sedans like the 1960s New Yorker and Charger, to trucks and vans like the Dodge A100 and B-series vans.

Because this is a significant drivetrain upgrade, it's important to ensure it's the right fit for your specific rear axle housing and gear ratio. The Detroit Locker is known for its bullet-proof construction and its ability to handle demanding applications, making it a reliable choice for those who need maximum traction. You'll want to confirm your rear axle is the 8.75-inch Ford style and that your axle shafts are 30-spline with a 1.28-inch diameter to ensure proper installation.
