E-Z Locker Assembly The Detroit E-Z Locker is an affordable easily installed traction device that replaces the spider gears in a stock differential. It is a very aggressive unit good for rockcrawling and mud runs but the road ride is not as smooth as stock . Ideally suited for use in the front axle of Wranglers as the vehicle is only used in rear wheel drive on the road so the steering is not affected.
