Teraflex leveling kit install question
Personally I did not do it on my leveling kit, and everything installed and rides just fine. I personally don't see the need. I feel certain if it was needed, then the manufacturer who spent hundreds if hours designing, manufacturing, and testing the kit would say so in the instructions.
