When was the last time that you have checked your air pressure in your tires? Tires are key to performance. SO ARE BRAKES !! I know that I already talked about checking your rear brakes. But, I just helped a guy work on his back brakes . The pins were stuck in the carrier and nothing that I did would make them come out. Blow torch. wrench. wouldn't even twist!! We brought new rear carriers. And installed them. MPG went up . Performance went up. And handling went up. He was very happy with his truck. said it drove like a completely different Blazer. He went from hating his truck to wanting to keep it and make it better . Performance could be found in the least likely places ! 4 caliper pins ! 4 pins ! was robbing this guy of a better performing truck !
