ReadyLIFT is proud to offer the most complete 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 69-6404 includes four (4) replacement front and rear sway bar end links, rear heavy-duty track bar relocation bracket, adjustable front track bar for axle positioning, new bump stops and bump stop pads to ensure the correct articulation of your suspension.  The ReadyLIFT 69-6404 kit also includes four (4) Bilstein 5100 Series shocks and our new front caster correction brackets to help correct the front geometry after lifting.

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 may require front exhaust spacers. This kit includes stainless steel exhaust spacers for 2012-up Jeeps for off road use.

Tire Fitment:

Requires aftermarket wheels.

35×12.50 on 4.5″ bs wheel or 8″ wheel with 4.5″/0mm offset or 9″ wide with 0 or -12 offset.

37×12.50 with flat fenders

When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer’s construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 8-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
