You are now in luck, SuspenisonMAXX is now offering a solution to your problem. If you are suffering from extremely high CV axle angles and driveline vibrations, you need our differential drop kit. The front differential is lowered in two locations, the four large differential spacers lower the differential cross member where it mounts to the frame. The additional spacers lower the differential where it is attached to the cross member. The SuspenisonMAXX diff drop kit also includes skid plate spacers. These components are both available with our Stage 1 & Stage 2 packages. All differential lowering components are made in the USA from Billet Aluminum. Don't gamble on tearing up another set of CV boots, get the SuspensionMAXX diff drop kit today!

2020 GMC 2500HD Denali.. Cognito Leveling kit, 22x14 American Forces and 33x14.50x22.. Ofcourse I ran that kit up a little more than recommended as I stuck such a wide wheel under it. I would have a bad gear clicking sound out of my cv axles when suspension drooped.. This kit illuminated that!! 100% recommend for every leveled truck!! Thanks!! Now if I can figure out some install instructions on the stabilizer bracket with the PISK.. Can’t find them anywhere..
I’m not sure if it took the tension out of my front end but this kit made my truck ride smoother and feel much better it’s a must have for leveled 2015 duramax. I would highly recommend if you have leveling kit on your duramax to put this drop kit on
