What gear ratios is this Detroit Locker compatible with?

This Detroit Locker is designed for Dana 35 axles with a ring gear pinion ratio of 3.54 and numerically lower. This includes common ratios like 3.73, 4.10, 4.56, and so on.

Does this differential require any special tools or modifications for installation?

Installation of a Detroit Locker typically involves a differential rebuild process. While it's a direct-fit replacement for the stock differential in compatible Dana 35 axles, it's recommended to consult the manufacturer's installation instructions and have the necessary tools for a proper setup.

What is the main benefit of a Detroit Locker compared to an open differential?

An open differential sends power to the wheel with the least traction. The Detroit Locker, however, locks both wheels together, ensuring that both wheels receive equal torque. This provides significantly improved traction, especially in off-road or slippery conditions where one wheel might lift or lose grip.

Product Details

If you're looking to get the most traction out of your rig, especially for off-road or demanding conditions, the Eaton Detroit Locker is a solid choice. This is a fully automatic locking differential designed for the Dana 35 axle, featuring 27 splines and compatible with gear ratios of 3.54 and numerically lower (like 3.73, 4.10, etc.). It works reliably in both forward and reverse directions, ensuring you have power to both wheels when you need it most, even if one wheel loses contact with the ground.

What sets the Detroit Locker apart is its bullet-proof, clutchless design. This means it's virtually maintenance-free and provides 100% locking engagement automatically, without any driver input required. When you apply power, it locks both axles together, sending equal torque to each wheel. As soon as you ease off the throttle or turn, it disengages to allow for easier steering. This unique mechanism is known for its strength and durability, making it a popular option for a wide range of vehicles, including the Ford Explorer, Jeep Wrangler, and Mazda B4000, among many others. The 1.14-inch axle shaft diameter and 7.56-inch ring gear diameter are key specifications to confirm for your specific Dana 35 application.

Installing a Detroit Locker is a significant drivetrain upgrade, often done during a differential rebuild. Because it's a mechanical locker, it offers a very direct and predictable feel when locked. It's important to ensure your axle housing and ring gear are in good condition before installation, as this locker demands a lot from the entire axle assembly. This differential is designed to keep both wheels driving, providing that ultimate traction for challenging terrain.
