Product Details
Starting with its 28-spline, 1.20-inch axle shaft diameter, this Eaton Detroit Locker differential is built for serious traction. It's designed to work with 3.25 and numerically higher gear ratios in a 9-inch rear end. This is a 100% automatic locking differential, meaning it engages without any input from you, ensuring both wheels are always driven, even if one loses contact with the ground. This clutchless design is maintenance-free and operates reliably in both forward and reverse directions, making it a robust choice for a wide range of vehicles, from classic Ford Broncos and Fairlanes to more modern Ford Aerostars and Econolines.
The Detroit Locker's strength comes from its unique, bullet-proof design. It's engineered to keep both wheels turning together, providing maximum traction when you need it most, whether you're navigating tough off-road trails or dealing with slippery road conditions. Because it's a mechanical locker, it doesn't rely on clutches or friction materials that can wear out over time. This means you get consistent performance and a maintenance-free operation, which is a big plus when you're deep into a build or just want reliable performance without constant upkeep.
When you're looking for a differential that provides uncompromising traction, the Detroit Locker is a solid option. Its straightforward, durable design has made it a popular choice for decades. It's important to note that this is a full-time locking differential, which means it will behave differently on pavement during turns compared to an open or limited-slip differential. For those who prioritize traction above all else, especially for off-road or performance applications, this differential delivers.
