This high quality system has been designed to retain the factory load carrying capacity and ride of the vehicle with minimal parts. The factory Ram Radius Arms are relocated with heavy duty 1/4" thick steel brackets for proper caster with the 5" lift. Super stout front and rear Track Bar drop brackets center the axles under the vehicle with the new ride height. The stock coil springs are retained with angular steel spacers to retain the factory front spring bow. This is an important feature with the stock springs as Chrysler designed the bow to aid in their unique alignment specs and ride. Flat spacers do not provide this. The rear coil springs are also retained with steel spacers keeping the weight carrying capacity of the vehicle intact. A Fabtech innovation with this Ram lift kit is the heavy duty steel front bump extensions. They retain the stock bump stop cushions for progressive damping and will not allow the suspension to over travel. This is a superior feature compared to replacement long length urethane bump stops as they can push out under harsh conditions and allow over traveling. This product ships in approximately 1 days
