Lifting your Jeep JK Wrangler improves ground clearance and allows for larger tires but it can have an adverse effect on suspension and steering geometry. Now you can have your cake and eat it too, thanks to Rubicon Express best on-road performing kit the 3.5-inch JK progressive coil 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 kit includes our new high steer kit made up of a new solid drag link that accepts OE tie rod ends while relocating the steering stabilizer above the drag link for increased ground clearance. The sport kit can improve the ride quality and handling on any 07+ JK or JK Unlimited with a 3.5-inch suspension lift.
Progressive coils have a longer extended length vs. Linear coils, maximizing droop travel. The progressive spring rate also results in a smooth ride over small bumps with enough spring rate to prevent harsh bottoming during full compression.
2010 Jeep Wrangler (JK) Rubicon Express 3.5" Progressive Coil Sport Lift Kit with Monotube Shocks - RE7145PM
Great lift, preforms well on road, I'd say better than a factory ride. I haven't had it off road yet but I'm betting that with the rest of the mods, it will be fantastic. I did the install my self in my garage in about 20 hours, it took that long mostly because of the trouble I ran into with the 10 year old factory parts were quite rusted and very stubborn. I didn't install the front bump stops because I don't have a 90 degree angle drill to be able to drill the required hole into the front spring perches. I decided to let Norcross 4WP do the install of the high steer kit, They advised against that and instead advised me of an adjustable super heavy duty Rubicon express adjustable track bar. I couldn't be more happy with their reccomendations and the results after the fustration that I went through with the original high steer kit portion of this lift kit. I only received the drag link...39 other parts were missing from my order. After a couple of phone calls, Norcross 4WP in Georgia made it right and redeemed themselves. Rubicon express needs to follow there own shops advise and remove the high steer kit, Which is known to be a problem, and add their HD forged adjustable Track Bar to this kit, and no drill front bump stops.
