"They lifted my truck to the perfect amount without having to use block to equal out the rear. However, for what they are, they are way too expensive. I ordered these thinking I would get shock extenders too for the price but they weren't included or needed. There are better lower price options for just keys IMO." —Raymond B from Hanover, PA bought a SuperKeys for a 2003 GMC Sierra.
