My shocks and springs are shot. Finally got my steering problems fixed, so I'm taking care of this next. I can get a new RC 2.5" lift for $100 from a buddy that owes me a favor. Obviously cheaper than used OEM stuff. If I did go that route, what else would be NEEDED. I can't afford to buy four sway bar ends, trac bar brackets etc. With 2.5" on rubi, is anything extra needed or is it all just "preferred."
