Overview
The Rubicon Express JL7141M is a 1.5 inch to 2.5 inch standard lift kit with monotube shocks for the 2018–2022 Jeep Wrangler Unlimited (JL), four-door models. It uses coil springs at the rear and includes monotube shocks at the front and rear.
The system is designed to clear 35-inch tires on a loaded non-Rubicon model and 37-inch tires on a Rubicon model. It fits the Unlimited Moab, Rubicon, Sahara, Sport and Sport S.
Key features
- Monotube shocks at the front and rear
- Coil spring lift at the rear
- Lift height range of 0 to 3.5 inches
- Designed for 35-inch tires, and 37-inch tires on Rubicon models
- The kit provides a suspension lift of 1.5 to 2 inches.
Coil spring lifts and monotube shocks
Monotube shocks use a single tube with a piston that moves through the fluid, a common design for shocks that need to keep a steady feel over repeated bumps. On a lifted vehicle the shock length and angle change, so the shock mounts and bushings carry more load than on a stock setup. Inspect the shock bodies for oil seepage and check that the mounting hardware is still tight after installation.
A coil spring lift also changes how weight sits over each axle, which can affect braking and steering feel. Tires and wheel offset are often replaced at the same time, and a lift may call for a new alignment before the tires wear unevenly. Keep tire pressure correct and rotate the tires on schedule, since uneven wear is one of the first signs that the geometry needs attention.
