Skyjacker 2020+ Jeep Wrangler (JL) 4in Component Box w/Dual Rate Long Travel Coil Springs
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.
