Andrew S.
Perfect Fit, 06 Tahoe Z71

I was concerned this cover would not fit my application, but it fit perfectly! The stock track bar on a 2006. Tahoe is very close to the diff cover, but this seemed to clear with under an1/8th inch clearance. I do have a an aftermarket Hellwig rear sway bar.

I love that it holds 1/2 quart overstock and that it has a magnetic drain plug.

I opted to go with a lube locker 10 bolt gasket and I don’t see any leaks whatsoever!
