This kit includes our front billet 2" lift spacers and our 1.5" rear lift billet block kit. We also include taller urethane bumpstops and new cotter pins. With this kit, using stock upper a-arms, there can be coilbucket contact, but at 2" lift most people never even notice. We designed this kit to function as best as possible...this is why its not a 2.5" kit....that is just too much for a 4wd.
