My question is are poly bushing and derlin bushings for the same application
poly(urethane)? bushing are used primarily for sway bars, but lately there are kits on the market that contain control arm poly bushings among a few other bushings. as for the derlin bushings and heim joints, I honestly dont know what they are, so I think its best that Jeff explains it.
