Overview
The Rubicon Express JL7100M is a 2.5-inch Super-Ride lift kit with monotube shocks for the 2018–2022 Jeep Wrangler Unlimited JL. It is a direct fit for the 4-door Moab, Rubicon, Sahara, Sport and Sport S trims.
The kit pairs coil springs with 2.5-inch diameter floating piston monotube shocks, which the brand says are tuned for all-terrain comfort and driver control. Front lower arms are 1.75-inch diameter 4130 chromoly Super-Ride parts.
Extended sway bar end links and extended bump stops are included. This is a Super-Ride short arm system, with monotube shocks at both ends. The lift height range is 0 to 3.5 inches, and the system clears 35-inch tires on loaded non-Rubicon models and 37-inch tires on Rubicon models.
Key features
- 2.5-inch diameter floating piston monotube shocks, included
- 1.75-inch diameter 4130 chromoly Super-Ride front lower arms
- Extended sway bar end links and bump stops
- Coil spring rates tuned for bump compliance and load handling
- Clearance for 35-inch and 37-inch tires depending on trim
Monotube shocks on the trail
Monotube shocks use a single tube with a floating piston, which keeps the damping consistent when the shock heats up on long descents. That consistency is useful for drivers who alternate between highway driving and rough trails. Monotube designs can be easier to inspect for oil leaks than twin tube units. Keeping the shock body clean makes leaks easier to spot during routine checks.
A short arm lift changes how the shock is loaded, so the shock length and mounting angles should be checked after installation. Look for worn bushings in the front lower arms, and inspect the sway bar end links, since they carry load during articulation. Confirm the steering stops are not binding at full lock.
- Check monotube shocks for oil seepage
- Inspect the bump stops for splitting
- Re-check the alignment after the first trail run
