What is the purpose of the dual rate coil springs in this kit?

The dual rate coil springs are engineered with two stages. The first 'Flex Rate' stage provides a comfortable ride and allows for maximum suspension flex during articulation. The second 'Ride Rate' stage engages only after compression past the Flex Rate, resulting in a smoother ride during normal driving conditions.

What does the transfer case lowering kit do?

The transfer case lowering kit helps to correct the driveline angle after lifting the vehicle. This is important for reducing potential driveshaft vibrations and ensuring a smoother power delivery, while also aiming to maintain as much ground clearance as possible.

Does this kit include everything needed for installation?

This kit is designed to be a comprehensive component box, including dual rate springs, control arms, bump stop spacers, sway bar end links, a transfer case lowering kit, a drop pitman arm, and a rear track bar bracket. It also comes complete with all necessary bushings and high-grade mounting hardware.

Jeep Wrangler 2003-2006

Product Details

If you're looking to give your 2003-2006 Jeep Wrangler TJ or LJ a significant lift and improved off-road capability, this component box from Skyjacker is a solid option. It centers around a pair of specially engineered dual-rate long travel coil springs. These springs have two stages: a 'Flex Rate' that offers a comfortable ride and allows for maximum articulation, and a 'Ride Rate' that engages when the suspension is compressed further, providing a smoother ride on the road. This design aims to balance on-road comfort with off-road performance.

Beyond the springs, this kit includes several other components to properly set up your suspension. You'll find longer replacement lower control arms designed to correct the caster angle, which is crucial for proper alignment after lifting. These arms feature durable, pressed-in rubber bushings for a quiet and comfortable ride. To keep your suspension travel safely in check, bolt-in bump stop spacers are included. Extended length sway bar end links are also part of the package, allowing your suspension to fully drop out without binding. For driveline integrity, a transfer case lowering kit is included to correct the angle and reduce potential vibrations, while also maintaining good ground clearance. A drop pitman arm is included to reduce the operating angle of the drag link, bringing it back into alignment with the track bar. Finally, a rear track bar bracket mounts to the axle to re-center it under the vehicle, improving handling and lowering the roll center to reduce body sway.

This kit comes complete with all the necessary bushings and high-grade mounting hardware, making it a comprehensive solution for your lift project. The components are finished with a resilient powder coat and zinc plating to resist corrosion, ensuring they hold up over time. Skyjacker has cycle-tested these components to ensure dependability and quality, and they are pre-set to minimize the chance of fatigue or sag.
