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.
Awesome ride and easy installation and looks great
Overall, love the product. Smooth ride all around with the monotone shocks and springs and couldn't be happier with the height and look I wanted to get out of it. Couple of issues I had was the upper hole for the rear track bar bracket didn't line up with the frame mount hole so I had to oversize the bracket hole to fit. Also, save yourself some time and just use some 2" long 5/16 bolts with washers and self locking nuts for the front bump stops instead of the provided self tapping bolts (they are worthless). Got the brake line brackets and exhaust spacers installed as well.
I was presently surprised to actually get 3.5" of lift for a 2.5" kit. The installation instructions need to be expanded for a first time installer. Make sure to disconnect the brake line brackets from the frame and the undercarriage so as not to damage the lines when dropping the axles. The new springs (coils) need to be compressed to fit into position and you can rent the tool at your local auto parts store. The most difficult part of the installation was the front shock top mounting nut and bushing. There is not an offset nut in order to tighten the top nut of the front shocks and I had to use channel lock pliers (no damage occurred) on the tube shaft in order to tighten and lock the nylon nut in place. The space on a 2016 JKU is very tight and I had to use needle nose pliers to set the nut in place. If possible use a ratchet box wrench to tighten the nylon nut into position.
Has a nice ride easy to install made the jeep look great
Raymond at the Redondo Beach location chose this kit based on my needs. I wanted good height, moderate off-road capability, and a good highway feel as my Gladiator is also my every day vehicle. PROS: very capable so far on trails (nothing advanced yet); excellent handling on highway; no rubbingat the front with 35’s. CONS: None.
I just upgraded my 2020 JT with the RE 3.5 suspension/lift. The added height is perfect with my new BF Goodrich 35’s. The feel on the road is extraordinary. Incan really feel the road and the kit handles the road very smoothly. Love this kit.
What a great upgrade. Ride is a lot smoother and lift height is perfect. The progressive coil springs really make a difference and the shocks are seriously what should come stock. Now wondering why I didn't get this done sooner. Thanks, Rubicon Express. The progressive coil lift kit with monotube shocks is perfect.
I had a Rough Country lift on my first jeep and though it was inexpensive it didn't provide a good ride and was very stiff. This lift was much better than stock suspension. The progressive springs absorb every obstacle with a comfortable ride on and off the road. This kit includes the bilstein shocks which are a great bargain. With this lift I clear my 35" tires.
