Wanting to level my new toy a 2002 1500 QC 4x4 .Reading posts on here ,sounds like alot of people just crank up torsion bar adjusters, others buy the torsion keys from Truxxx, Readylift etc. If the torsion bar stays in the same position in front what is the difference,other than a flatter mating surface to the adjustment bolt ? Or do the kits change the front mnt. somehow?
