Overview
The Rubicon Express JL7142 is a 3.5-inch standard coil lift kit for the 2018–2022 Jeep Wrangler (JL). The rear lift uses coil springs, and the control arms and other components remain in place.
It is a budget-minded suspension package designed for both road and trail use. The lift height range is 0 to 3.5 inches, so 3.5 inches is the top of that range. The kit is made for 37 inch tires, and the shocks are not included.
Key features
- 3.5 inch standard lift
- Rear coil spring lift method
- Control arms and other components retained
- Budget-minded package designed for on-road and trail use
Budget lifts and what to add
A budget coil spring lift is a practical way to add ground clearance and room for larger tires, but it leaves some parts for the owner to plan. Because the shocks are not included, the ride and damping depend on the shocks chosen. Pick shocks rated for the new ride height and spring rate, and keep the rest of the suspension in good condition so the lift performs as expected.
Before the install, check the brake lines, the driveline and the wiring for length at full droop. Plan for a wheel alignment after the lift and for tire clearance testing at full compression. Over time, look at the springs, the control arm bushings and the shock mounts for wear, since loose or worn parts can affect steering and stability.
- Select shocks rated for the new height
- Measure driveline angles after installation
- Inspect control arm bushings periodically
