Overview
The Rubicon Express JL7142PB is a 3.5 inch standard coil lift kit with piggyback monotube reservoir shocks for the 2018–2026 Jeep Wrangler (JL). It lifts the vehicle with coil springs at the rear, and the kit comes with front and rear monotube reservoir shocks.
The kit is a budget-minded suspension package that retains the control arms and other components. It gives a lift height range of 0-3.5 inches and is designed around a tire size of 37 inches.
Key features
- 3.5 inch standard coil lift kit
- Front and rear monotube reservoir shocks included
- Coil springs for the rear lift
- Control arms and other components are retained
- Lift height range of 0-3.5 inches
- Listed tire size of 37 inches
- Direct-fit design
Choosing lift and tire setup
A suspension lift raises the body relative to the axles, which opens room for larger tires but also changes how the vehicle behaves. Coil springs at the rear carry the added height, and the shocks control how those springs compress and rebound. Shocks with a reservoir have extra oil capacity, which helps them keep working consistently when the suspension is worked hard on rough trails.
When choosing a setup, consider the tires you plan to run and the wheel offset you have. A taller tire adds to the effect of the lift, so check for rubbing at full lock and under suspension compression. Steering and brake components may also need inspection after the lift, since their angles change with ride height.
- Check driveline angles once the lift is installed
- Inspect brake lines for stretch at full droop
- Replace worn bushings while the suspension is apart

Installation notes
Professional installation is recommended because suspension work changes ride height, steering geometry and brake-line and driveline clearances. Torque fasteners to specification, recheck them after the first drive, and verify alignment once the lift is in. Check tire and wheel clearance at full steering lock and follow local rules on lift height.
