Diff Guards: 
All sizes $69.95 + Shipping
Fits your 8.25, Model 20, and Dana 30, 35, 44, 60

Our cover guards not only give you superior protection for your expensive diff covers and gears, but are designed to help you slide up and over rocks and debris, instead of just taking a hit straight into the cover and stopping the vehicle.

As you can see in this picture, there is no loss of clearance and there is definitely some serious protection.

This could have been prevented by a Four.X.Doctor Diff Guard.
Don't let this happen to you.
