The Skyjacker 21-23 Jeep Wrangler JL Non-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 progressive, two-stage dual rate coil spring, it features a flexible first stage for improved articulation and comfort, which expands during full droop to maintain tire contact and keep springs seated properly. The springs are constructed to work seamlessly with the Wrangler's suspension dynamics, providing increased travel and durability for demanding off-road conditions. This kit ensures optimal suspension geometry and stability, supporting enhanced articulation and handling.

Designed specifically for 2021–2023 Jeep Wrangler JL models, including non-Rubicon 4xe 4-door variants, this suspension kit is tailored to fit vehicles with the factory chassis and drivetrain configurations. It is ideal for off-road enthusiasts seeking increased ground clearance and articulation, with components such as long travel coil springs, adjustable front track bar with heavy-duty bushings, rear track bar mount, bump stop spacers, and extended sway bar end links included for comprehensive suspension enhancement. The kit is a bolt-on upgrade that maintains factory-like handling and stability while providing superior off-road performance and articulation.

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.
