Bought 2 sets. 1 set for 2007 Cadillac Escalade EXT and one set for 2008 Envoy Denali. The Escalade kit worked great and fitted perfectly with no issues, but the Denali kit doesn't fit the car at all no matter which repair or tire shop I go to. They think there is a software lock that requires them to be paired with the merchant. Just something buyers should know about future purchases.
