The ReadyLift 4 Inch Coil Spring Lift Kit for Jeep JK Wrangler 2007 to 2018 4WD is a Moab-tested and trail-proven complete suspension upgrade that lifts the front 4 inches and the rear 3 inches for a level and confident stance with clearance for up to 35-inch tires on stock fenders and up to 37-inch tires with flat fenders. Part number 69-6401, this all-in-one system includes four SST3000 shocks, front and rear coil springs, front and rear sway bar end links, a rear track bar relocation bracket, front and rear bump stops and pads, and all required hardware and instructions.
At IMM Hawaii Parts, we carry this kit for JK Wrangler owners who want a complete and properly matched lift system that delivers balanced performance on the highway and serious capability on the trail without requiring a parts hunt to complete the installation.
ReadyLift 4 Inch Coil Spring Lift Kit For Jeep JK Wrangler With SST3000 Shocks
The four SST3000 shocks included in this system are tuned specifically for the JK Wrangler running 4 inches of front lift and 3 inches of rear lift, delivering a balanced and predictable damping character that handles highway driving comfort and trail performance with equal capability.
Vehicle-specific shock tuning is one of the most important factors in how a complete lift system performs in real-world use, and the precision-tuned SST3000 shocks in this kit are what give the lifted JK smooth highway manners alongside the control and stability needed for serious off-road articulation. Customers at IMM Hawaii Parts consistently choose this complete kit over mixing individual components because the matched shocks and springs deliver a cohesive suspension feel that mismatched components simply cannot replicate.
Precision-Tuned Coil Springs for Front and Rear Balance
The front and rear coil springs in this system are precision-tuned for the JK Wrangler platform running the specific lift heights delivered by this kit. The front coils deliver 4 inches of lift and are rated to handle the weight distribution of a JK with common front-end accessories, while the rear coils deliver 3 inches of lift and are tuned to balance the rear of the Wrangler with the front lift for a near-level stance that looks and handles correctly. Matched and tuned coil springs are what give this system its smooth highway ride alongside the serious trail control that Wrangler owners expect from a properly built lift.
Geometry Correcting Components for Tight Steering and Handling
The rear track bar relocation bracket in this kit corrects the track bar angle after the 3-inch rear lift is installed, keeping the rear axle properly centered and maintaining the tight and predictable steering feel that the factory JK suspension was designed to deliver. The front and rear sway bar end links correct the sway bar geometry after the lift, maintaining roll stability and handling control on paved roads and trails alike. Together, these geometry-correcting components ensure the lifted JK tracks and handles correctly rather than developing the vague or unpredictable steering feel that can occur when lift is added without addressing the downstream geometry changes.
Tire Fitment for Stock and Flat Fenders
This lift kit clears tires up to 35 inches in diameter on stock-style JK fenders without trimming, and up to 37 inches with flat fenders installed. The 35-inch no-trim fitment makes this kit a practical choice for JK owners who want to run a meaningful tire upgrade without modifying the factory fender configuration, while the 37-inch capability with flat fenders gives dedicated off-road builders the clearance to run the aggressive tire sizes that the JK platform is known for.
Important Notes Before Purchasing
On 2012 and newer JK models, driveshaft and exhaust modifications are required after the lift is installed. ReadyLift recommends stainless exhaust spacers part number 47-6310 for off-road use on these model years. Lifting a solid axle vehicle can shift the axle position, and an adjustable track bar sold separately can be used to recenter the axle precisely after installation. Professional alignment is recommended after the lift is complete.
