Rubicon Express 3.5" Sport Suspension System for 07-18 Jeep Wrangler Unlimited JK 4 Door

Starting at

Lifting your Jeep JK Wrangler improves ground clearance and allows for larger tires, but there is always a chance it can have an adverse effect on suspension and steering geometry. Now you can safely and smoothly have the lift you require thanks to Rubicon Express' best on-road performing kit — the 3.5-inch JK Sport Kit. This kit corrects steering and control arm geometry to eliminate bump steer and increases anti-dive for better braking and improved safety. The system also includes a new high steer kit made up of a solid drag link that accepts OE tie rod ends while relocating the steering stabilizer above the drag link for increased ground clearance. This RE 3.5" Sport Suspension Kit can improve the ride quality and handling on any 07+ JK or JK Unlimited with a 3.5-inch suspension lift.


Included High Steer Kit: Rubicon Express not only gives you added ground clearance from this kit, but it also includes a high-steer kit in order to give you better control and agility when covering bumpy or rocky terrain.

Shock-worthy Springs: The RE 3.5” Sport Suspension System was created to upgrade your suspension and improve your shock absorption. The kit includes 3.5” front and rear replacement coil springs that are ready for action, so whether you are off-road or rolling around pothole city, your ride will be as smooth as butter.

Limited Lifetime Warranty: Rubicon Express ensures their products are free of defects and that the materials are made to last the life of the product. RE's Limited Lifetime Warranty will replace or repair any products that are proven faulty or defective prior to installation and use.
