The RS6579B kits were developed using 37x12.50R17 tires on a 17x8 wheel with 6" of back space. Please note, to prevent tire clearance issues wheel must have between 5.5 and 6 inches of back space. Under some extreme off-road situations, some trimming of the front air dam/fascia area may be necessary for extra clearance. Shock absorbers are NOT included with this kit and are sold separately. Front and rear shocks can be purchased using the selection box located above this item description. Please note, Rancho offers two different front coil springs, one designed for 5.9L or 6.7L Cummins Diesel equipped trucks and another for 5.7L Hemi Gasoline engines. Coil springs are NOT included in the RS6579B kit. Also note that the correct U-bolt for your Ram will be based on the Engine type. The Cummins Diesel equipped trucks require Rancho U-Bolt Kit # RS747. The 5.7L Hemi Gasoline Engine equipped trucks require Rancho U-Bolt Kit # RS748. Dodge Ram trucks equipped with a 2-piece rear drive shaft will also need the Rancho carrier bearing drop kit, Rancho # RS6608 - purchased separately. Please be sure to select the correct spring for your application when placing your order.
