Hey all, Ive got a 85 Suburban Diesel 4x4, immaculate condition (im from SoCal). Ive got a question about lifting it. Most 4-6 inch lift kits seemto run anywhere between 400-700 bucks, fo a basic system that is. Most of them come with an OPTION of adding the rear leaf springs, and some come with just rear blocks. My question is what are the benefits of using the rear spring as opposed to using a rear block which is obviously cheaper. Im from SoCal and dont plan on doing any major off-roading, just go on snowboarding trips and whatnot. Maybe go off th trail if i need to, but nothing like you good ole boys seem to be into. Thanx.
