Just purchased an '05. First mods gonna be tires. I need some suggestions. When I push the AHC button my dash light just blinks but the truck doesn't raise or lower. I want to run bigger tires than stock but still maintain a stock ride. Should I go with a lift or stay with oem parts? Plan to ditch the AHC. What's some good possible suspension combinations I can go with? Maybe worth mentioning that my wife is 12weeks pregnant so this car would be used as a family hauler but I like the more aggressive tire setup.
