Zeus hit it on the head with the labor. The shop that does mine is expensive, they want 2300 for an 11...thats just gears, labor and modding your carrier.
My locker is torque biased and unlocks when neqiotating turns Zeus. It works the same as a real Detroit Locker. Normal driving I dont have any tire hop or spin turning unless I hammer down on it. My tire is disenigrating bc I cant stay off the skinny pedal
