If you're just looking to clear larger tires you can go with a Body Lift
or a Coil Spacer Lift
and be all set. Or combine the two styles to net out 4 inches of lift. If you're looking for the added flex and offroadability of a spring lift, there isn't a lot in the price range of the RC kit. A lot of people will tell you that their bushings are no good and will wear quickly.
