The Skyjacker 21-23 Jeep Wrangler JL Rubicon 4XE 4 Door 4.5in Comp. Box with Dual Rate Long Travel Coil Springs is a high-performance suspension upgrade designed to enhance off-road capability and ride quality. Engineered as a 2-stage dual rate coil system, it features a progressive spring rate that transitions from a flexible first stage to a stiffer second stage, providing a comfortable ride while maintaining increased articulation during full droop. The springs are constructed to keep the tires in contact with uneven terrain, ensuring optimal traction and stability. The kit includes components such as adjustable front track bars with heavy-duty rubber bushings, a rear track bar upper mount bracket, bump stop spacers, and extended sway bar end links, all designed to maintain proper suspension geometry and vehicle handling.

This suspension kit is specifically designed for 2021-2023 Jeep Wrangler JL Rubicon 4xe models with 4-door configurations. It is a bolt-on upgrade that enhances off-road performance while preserving factory-like handling and stability. The components are side-specific for the rear coils and include all necessary mounting hardware for a straightforward installation. Ideal for off-road enthusiasts and those seeking increased ground clearance and articulation, this kit ensures the electronic stability control system functions within factory parameters. It is suitable for off-road adventures, trail riding, and daily driving where durability and performance are paramount.

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-inch 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.
