Skyjacker 07-18 Jeep Wrangler (JKU) 4in Lift Kit Component Box w/ Dual Rate Long Travel Springs

Skyjacker is known for building suspension components that handle tough off-road conditions. This 4-inch lift kit component box is designed specifically for your 2007-2017 Jeep Wrangler JKU, giving you the clearance and capability you need for bigger tires and more challenging trails.

At the heart of this kit are the progressive, dual-rate long-travel coil springs. The first stage, or Flex Rate, offers a comfortable ride on the road while allowing for significant expansion when the suspension drops to full droop. This helps keep your tires planted on uneven terrain and ensures the springs stay seated. Once you compress past the Flex Rate, the second stage, the Ride Rate, engages for more controlled stability. The included ADX 2.0 Adventure Series shocks feature remote reservoirs and an internal floating piston to prevent oil and gas from foaming, ensuring consistent performance whether you're crawling or hitting higher speeds.

This kit also addresses other critical suspension points. Extended length sway bar end links allow for full articulation when the suspension is at full droop. You'll also find a replacement front adjustable track bar with heavy-duty bushings and a rod end, along with front and rear bump stop spacers to safely manage suspension travel. To correct axle angles and improve handling, a rear track bar lower axle mount bracket and a Dana 44 track bar mount brace are included, strengthening the factory mount which can be prone to failure. Eccentric alignment cam bolts are also provided to help correct caster and pinion angles. Everything you need, including high-grade mounting hardware and bushings, is included to get your JKU lifted and ready for adventure.
