The Skyjacker 21-23 Jeep Wrangler JL Non-Rubicon 4XE 3.75in Compensation Box with Dual Rate Long Travel Coil Springs is a high-performance suspension upgrade designed to enhance off-road capability and ride quality. Engineered with 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 proper coil seating. The springs are constructed to work seamlessly with the Wrangler's suspension dynamics, providing increased travel and durability. The kit also includes components such as bump stop spacers, extended sway bar end links, and adjustable track bars, all designed to optimize suspension geometry and ensure proper functioning of the Electronic Stability Control system.

This suspension kit is specifically designed for 2021-2023 Jeep Wrangler JL models, excluding Rubicon 4XE variants. It is a bolt-on upgrade that enhances off-road performance while maintaining factory-like handling on the street. The kit includes dual rate long travel coil springs, adjustable front track bar with HD rubber bushings, rear track bar upper mount bracket, bump stop spacers, and extended sway bar end links with HD bushings. Suitable for off-road enthusiasts and daily drivers alike, this setup improves articulation, stability, and ride comfort, making it ideal for challenging terrain and demanding driving conditions.

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.
