The Skyjacker 2020+ Jeep Wrangler (JL) 4-inch Component Box with Dual Rate Long Travel Coil Springs is a high-performance suspension upgrade designed to enhance off-road articulation and ride quality. This kit features a progressive, two-stage dual rate coil spring system, with a Flex Rate for comfortable handling and increased flex during full articulation, ensuring tires maintain contact with uneven terrain. The springs are engineered to work seamlessly with the Wrangler's unique suspension geometry, providing improved durability and performance. The package includes carefully designed components such as adjustable front track bars with heavy-duty rubber bushings and adjustable rod ends, rear track bar upper mounts for proper axle centering, bump stop spacers to control suspension travel, and extended sway bar end links for full articulation at droop. These features work together to maintain factory-like stability and handling while offering increased off-road capability.

Designed specifically for 2020 and newer Jeep Wrangler JL models, this kit is suitable for vehicles with a 4-inch lift and is ideal for off-road enthusiasts seeking enhanced articulation and suspension travel. The components are bolt-on replacements that do not require extensive modifications, ensuring straightforward installation. The rear coils are side-specific to match the vehicle’s suspension handling characteristics, and the included bump stop spacers and sway bar end links help keep the suspension geometry within factory parameters. This kit is perfect for off-road adventures, trail riding, and improving overall vehicle performance in rugged conditions, providing a durable, reliable upgrade for Jeep JL owners looking to maximize their vehicle’s off-road potential.

Overview

Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. Spring rate progression is from a 1st Flex Rate to a 2nd Ride Rate. The 1st Flex Rate stage delivers a comfortable ride with the ability to flex for increased articulation. The flex rate expands during full articulation as the suspension drops (full droop). This keeps the coil springs seated in the upper coil mount/bucket and the tires in contact with the terrain. The 2nd Ride Rate stage only engages after compression past the flex rate. Engineered to coordinate with the Wrangler's distinctive suspension handling characteristics, the rear coils are side specific. The replacement Front Adjustable Track Bar includes Skyjacker installed pressed-in HD OEM style rubber bushing and an adjustable 3/4- in. Heavy-Duty Rod End, Jam Nut and Alignment Bushings. A heavy duty Rear Track Bar Upper Mount Bracket is included to center the axle under the vehicle properly. Front and Rear Bump Stop Spacers bolt onto the axle bump pads and keep the suspension travel safely in check. Front and Rear Extended Length Sway Bar End Links allow full articulation as the suspension drops (full droop). These sway bar end links include Skyjacker installed pressed-in HD OEM style rubber bushings. Proper suspension geometry ensures the Electronic Stability Control (ESC) system functions within factory parameters.
