Gm Certified Question

[Yotaman]

I bought a 06 GMC Sierra CC recently that is GM Certified. Will it void the powertrain warranty to have the rear end lowered 1 to 2 inces so that it sits level ? Thanks for any advice.

Better ask the dealer that certified it. Dealers treat modifications differently; some dealers are ok with a few mods, while other dealers will boot you out of the service drive.

 

Just ask your dealer.

I doubt it. They'd have to prove that the failure was caused by the drop.
