Eaton Detroit Locker Differential 30 Spline 1.29in Axle Shaft Diameter 3.54-5.29 Ratio Rear 8.4in

If you're looking to significantly improve traction for off-road adventures, towing heavy loads, or just want a more capable vehicle, a locking differential is a serious upgrade. The Eaton Detroit Locker is a popular choice for drivers who need maximum grip in challenging conditions. This unit automatically locks both rear wheels together, ensuring that power is sent to both tires simultaneously, even if one wheel loses contact with the ground. This means you can keep moving forward when other vehicles might get stuck.

The Detroit Locker is known for its bullet-proof design and 100% automatic operation. You don't need to do anything; it engages and disengages on its own as you steer and accelerate. It works reliably in both forward and reverse, and its clutchless, maintenance-free design means fewer parts to worry about over time. This particular model is built for rear axles with an 8.4-inch ring gear, features 30 spline axle shafts, and is compatible with gear ratios from 3.54 up to 5.29. It's a well-built unit designed for demanding use.

This differential fits a range of vehicles, including popular models like the Toyota Tacoma, Toyota 4Runner, and Toyota Tundra. When installing, it's important to ensure your axle housing and ring gear size match the specifications for this locker. Because this is a significant drivetrain modification, it's always a good idea to consult with a professional mechanic or refer to the manufacturer's installation guide for proper setup and any additional components you might need, such as new bearings or installation kits.
