Busted Knuckle 13 bolt diff covers are the best of the best!
1/4" and 3/8" thick steel and can take everything you can throw at it.
This cover allows you to shave the bottom of the housing for extra ground clearance. A sawzall works great for cutting the lip off. You can also run the cover on a stock 14 bolt without shaving the differential. No ring-gear machining is required and no welding is required.
Allows for 1-3/8" extra ground clearance
Has a fill plug in the face of the cover
Larger oil capacity than the factory setup.
We stand behind our product. If you can break it, we will give you a new one!
Cover comes with hardware.
*** Old housings use 3/8 course thread bolts, New Ribbed housings use M8x1.25 bolts. Please select your differential so we know what bolts to send.***
