The "BTF Toyota 8" Rear Kryptonite Diff Cover" was designed with pure function in mind. Like all of the Kryptonite Series Diff Covers the BTF Toyota 8" Front Kryptonite Diff Cover is fabricated from 1/4" high-strength steel plate. The cover welds on over the stock housing. You are not required to remove any portion of the stock diff. All diff covers are shipped unpainted.
This is more than just a cover. It adds strength to the front of the axle on either side of the "hump" where it is the weakest. It welds to the housing with 1 1/2" long stitches to prevent warpage and allow for dirt and mud to drain. The fill plug recess is fabricated with 1 3/4" round tube to strengthen the cover in the area of the plug and also to prevent the fill plug from dropping into the cover.
Note: Some modification to the cover will be required to work with leaf-sprung front-ends. The cover must be clearanced to fit over the inboard passenger side u-bolt.
