Looks great and let's me drain/fill

Summit RacingSummit Racing Verified Purchase

This thing not only looks awesome, it also let's me drain and fill fluid without ever having to take it off. If you are changing the fluid in your rear end, ditch the standard steel cover which will eventually leak anyway. Get this thing and be good for a long while.
