The Detroit locker provides maximum traction for off-road or racing use. The heavy-duty case and internals provide a dramatic increase in strength while giving 100% torque to both tires. The mechanically-operated unit works by locking while under power and unlocking when you let off the gas, allowing you to turn.

GU6210 Upgraded 14 bolt hub seals.

If you have constantly leaking hub seals or a pitted/damaged seal surface, these hub seals are your answer.  This is a two part seal: the inner "ring" slides over the seal surface on the spindle and seals it, no moving parts against the spindle.  The seal surface is integrated as part of the seal, so it doesn't matter what shape your spindle is in.  What it all comes down to is these seals WORK, and they seal MUCH better than the factory seal did!
