This 4 inch lift kit from Rugged Ridge fits 07-18 Jeep Wrangler JK.

Includes 4 powder coated, E-coated 5170H hot rolled bar 5/8 inch coil springs, set to factory rates for longer life and better ride! Each kit includes a rear track bar brace to strengthen the original track bar mount. Kit includes sway bar disconnects for more articulation off road Each kit includes a rear track bar brace to strengthen the original track bar mount ORV uses tough, over built extended control arms for added strength and performance. In most cases control arms are longer than factory to adjust for caster. 4-Door JK's will get on average a 4 inch lift. Two door models will get up to a 5 inch lift. Due to the changed pinion angle, we highly recommend a new drive shaft be installed when using any 4 inch or greater lift kit on a 4-Door Wrangler. A new drive shaft will be required on any 2007-12 2-Door Wrangler due to the shorter wheel base. All 4 inch Kits require a drop pitman arm. (Sold separately: Part number 18006.55).
