The Rubicon Express 2.5” Super-Ride Suspension Lift Kit is specifically designed for the Wrangler JL 4 Door to not only lift the vehicle for upgrading to larger wheels and tires, but to increase performance off road while still maintaining a comfortable ride for daily driving. The replacement coil springs are precision tuned for bump compliance and load handling. The Monotube shocks are designed for the Wrangler JL to maximize overall driver control and all terrain comfort. This easy to install kit includes all of the necessary components to lift and level the Jeep without sacrificing any OE ride handling characteristics. Once installed, this lift kit will allow fitment for 35” tires on Sport/Sahara editions and up to 37” tires for Rubicon edition Wrangler JL 4 door vehicles.
