The ICON Vehicle Dynamics Stage 8 2.5" Suspension System for the 2018-UP Jeep Wrangler JL is designed for the driver looking to drastically improve the performance and ride quality of their vehicle. This Stage 8 system includes 2.5" lift dual rate coil springs, upgraded 2.5 Series remote reservoir shocks with vehicle specific valving and ICON's CDC (Compression Damping Control) technology, tubular steel adjustable front upper links, fixed front lower links, fixed rear upper links, adjustable rear lower links, adjustable front and rear track bars, bump stop spacers, sway bar links, and all necessary hardware to complete the installation. With this combination of components, ICON was able to increase wheel travel numbers by over 30% (3" front, 2" rear), redefining the potential of the 2018-UP JL. The front lower links included with this system are constructed from thick wall steel tubing, provide increased castor numbers, and feature dual durometer bushings for noise free operation, maximum articulation, and minimal bind. The Stage 8 system allows for fitment of 35" tires when used with ICON's recommended wheel specifications. For users looking to install 37" tires, an optional bump stop spacer kit (PN: 22029) is available.
