What tire size does this system clear?

ICON specifies clearance for 35-inch tall tires with no modifications. You can run 37-inch tires with aftermarket high-clearance fenders installed.

What is included for steering correction?

The system includes high-steering components and track bar drop brackets to correct the steering geometry that changes with a 4.5-inch lift. These prevent bump steer and maintain proper steering response.

How does Stage 3 compare to Stage 4 for the JK 4.5-inch lift?

Stage 3 includes 2.5-inch reservoir shocks without the CDC valve adjustment. Stage 4 (K24004) adds the CDC valve upgrade to the same shocks, giving you externally adjustable compression damping. All other components are the same between the two stages.

Product Details

ICON's 4.5-inch Stage 3 suspension system for the 2007-2018 Jeep Wrangler JK is a complete lift package that includes everything needed to get 4.5 inches of lift height properly. This is not just springs and shocks -- it includes dual-rate coil springs, track bar drop brackets, high-steering components, bump stop spacers, rear brake lines, rear sway bar links, a complete set of front and rear link arms, and 2.5-inch remote reservoir shocks at all four corners.

The dual-rate coils handle the ride quality balance that makes or breaks a Jeep lift kit. A softer initial rate keeps the on-road ride comfortable, while a firmer secondary rate activates under compression to prevent bottoming out on the trail. The 2.5-inch remote reservoir shocks maintain consistent damping by running cooler than standard shocks during heavy use, which matters when you are wheeling hard on a hot day.

High-steering components are included to correct the steering geometry that changes when you lift a solid-axle vehicle 4.5 inches. Without these, you would get bump steer and vague steering feedback. The full set of front and rear link arms further ensures that the axles track correctly through the suspension travel, rather than wandering as the factory arms work at angles they were not designed for.

ICON rates this system for 35-inch tall tires with no modifications and 37-inch tires with aftermarket high-clearance fenders. That is serious capability for a JK build. The system ships in multiple boxes given the number of components, and professional installation is the way to go given the scope of the work involved.
