The ReadyLIFT Terrain Flex 4-arm Coil Spring Lift Kit with (4) heavy-duty control arms is the premiere choice for the Jeep JL Wrangler owner who demands an incredibly high-quality ride on road, while maximizing off road and rock-crawling mannerisms. The 69-6837 kit includes the best of everything and includes 4 front heavy-duty DOM tube steel front control arms. Each control arm is fitted with ReadyLIFT's proprietary Terrain Control Technology (TCT) bushings in forged housings. TCT bushings provide greater articulation and range of motion so they are far superior to the factory bonded bushings that resist suspension flex. These new heavy-duty arms provide increased ground clearance and improve caster geometry for a great ride on the road. Four linear rate coil springs provide 3.5" of lift mated with bump stop extensions to control compression and tire contact during suspension articulation. A new rear track bar relocation bracket and ReadyLIFT's new JL-specific heavy-duty adjustable front track bar ensure your lifted Jeep JL will drive and handle amazing! And of course the icing on this exceptional new JL suspension offering is the inclusion of Falcon's Series 2.1 monotube performance shocks for all four corners. These fixed-rate, purpose-built, custom-tuned shocks are engineered to deliver increased stability, improved ride quality, and comfort for daily driven Jeeps. You'll be shocked at how good your JL will ride and drive on the street and on the trail!


NOTE: This kit is not compatible with Wrangler or Gladiator optional powertrains including, but not limited to, the 3.0L Diesel, Rubicon 392, and 4xe editions.

Allows for up to 37" tall tires on JL Rubicon.

Allows for up to 35" tall tires on JL Sahara/Sport

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: 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 10-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.

Please read Instructions thoroughly and completely before beginning installation. Installation by a certified mechanic is recommended.

Estimated Installation Time: 7 Hours +/- 1 hour (excluding alignment and wheel/tire assembly)
