    With the overwhelming success of our 3.0" SST Lift Kit, ReadyLIFT is proud to introduce the 4" SST Coil Spring Lift kit for the 2007-2017 Jeep Wrangler JK! Due to popular demand from customers our research and development team have designed a Jeep Lift Kit that incorporates many of the great features of our 3.0" SST Lift Kit along with off road performance coil springs. This kit offers (4) Progressive Wound Coils to ensure unsurpassed On-Road mannerisms as well as increased Off-Road capability. Kit includes (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 includes shock extensions front and rear to accommodate your factory shocks and ensure the factory ride of the vehicle as the factory designed.

    2012-UP vehicles will require driveshaft and exhaust modifications.

    Recommend 47-6310 stainless steel exhaust spacer for 2012-up Jeeps for off road use.

    The ReadyLIFT 4.0" SST 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!

    **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 adjustable track bar available through most off-road parts dealers, check with your local dealer for options in your area. If you have any questions please contact our ReadyLIFT customer service department.
