Q:Will this work with my 2012 Escalade even though it is a different style? Is this a better product? Show Less
Dwayne M.
A:BEST ANSWERHi Dwayne, thanks for initiating contact. This is a direct fit for the 2012 Cadillac Escalade. Yes, Dayco is a good and reliable brand. However, you may mean it is a different part you need since you mentioned that what you are replacing is a different style. I suggest calling our parts specialists at 1-866-529-0412 to provide the vehicle information so we can help you look for the right part. Have a good one. Show less
