MOAB Tested! Trail Proven! ReadyLIFT is proud to offer a 4" Coil Spring Lift kit for the 2007-2018 Jeep Wrangler JK! This kit offers four (4) precision crafted coil springs to ensure unsurpassed on-road manners as well as increased off-road capability. Kit includes four (4) replacement front and rear sway bar end links, rear track bar relocation bracket, new bump stops and bump stop pads to ensure the correct articulation of your suspension. The ReadyLIFT 69-6400 kit DOES NOT include shocks. The ReadyLIFT 69-6400 kit includes shock extensions front and rear to accommodate your factory shocks and ensure the factory ride of the vehicle as the factory designed. The ReadyLIFT 4.0" Coil Spring Lift Kit lifts your Jeep JK Wrangler 4.0" in front and 3.0" in the rear for a lifted and level stance suitable for installation of 35" tall off-road tires. With the use of "flat fenders" you can install 37" tall tires. This kit allows you to confidently take your Jeep anywhere you want, on or off road, without sacrificing a quality ride or handling characteristics. The increased ground clearance provides many more off road opportunities than with a stock suspension along with the ability to install larger wheel and tires for the truly great lifted off road appearance! NOTE: 2012-UP vehicles will require driveshaft and exhaust modifications. Recommend 47-6310 stainless steel exhaust spacer for 2012-up Jeeps for off road use. NOTE: Installing a lift kit on any solid axle vehicle will alter the position of the axle. This can be corrected with the addition of an available adjustable track bar.
