Rough Country 66044 is a 6 in. long arm suspension lift kit built for 2018-2023 Jeep Wrangler Unlimited JL 4WD 4-door models that need added ride height, better trail articulation, and controlled road manners from one complete system. The true 4-link long arm layout uses longer-travel control arms to reduce suspension bind and control rear steer, while M1R monotube shocks, dual-rate coils, and an upgraded CV front driveshaft support confident use on pavement and off-road routes.
Rough Country 66044 Features:
- True 4-link long arm suspension geometry helps the axle cycle more smoothly and reduces the rear steer that can make a lifted Wrangler feel unsettled.
- M1R monotube shocks are matched to the system for controlled damping during highway driving and repeated off-road suspension movement.
- Adjustable upper and lower control arms for the front and rear use heavy-wall DOM tubing with adjustable flex joints and rubber bushings for strength and serviceable alignment tuning.
- Heavy-duty forged solid steel adjustable track bar helps center the axle after the 6 in. lift height is installed.
- Custom-tuned dual-rate coil springs balance added ground clearance with ride control for mixed street and trail use.
- Laser-cut mounting brackets are made from 0.25 in. high-tensile steel to handle harsh trail loads.
- Bolt-on design installs without welding and does not require crossmember removal.
- Quick-disconnect sway bar links let drivers transition from street driving to added trail articulation more easily.
