Overview
The Rubicon Express JT7141 is a 2.5/3.5 inch standard suspension lift kit for the 2020–2022 Jeep Gladiator JT. It is a direct fit for the Gladiator JT trims covered below, and the rear lift uses coil springs.
The specifications give a lift height range of 0 to 3.5 inches and a 35-inch tire size. The kit does not include shocks, and neither the rear nor the front has a shock listed in the specifications.
The system increases ground clearance and extends wheel travel without requiring driveshaft changes or modifications to the exhaust or brake lines. It makes room for 37-inch tall tires.
Key features
- 2.5/3.5 inch standard suspension lift
- Coil spring rear lift method
- Shocks not included, and no shock brand listed
- Increased ground clearance and extended wheel travel, per the brand
- Room for 37-inch tall tires.
Choosing shocks for the new height
Because a lift of this type raises the body relative to the axles, the existing shock length often becomes the limiting factor. A shock that is too short can bottom out before the suspension reaches full travel, while one that is too long can bind at full droop. Matching the shock to the new ride height is the step that most affects how the truck rides after a coil spring lift.
Coil spring lifts on solid axle trucks rely on the control arms and track bar to keep the axle located, so worn bushings are worth replacing when the shocks are changed. Check the bump stops and brake hose length at the same time, since both are affected by the new height. Periodic inspection of the springs, shock mounts and steering linkage helps catch wear early.
- Check shock length at full extension and compression
- Inspect bushings before reusing old hardware

Vehicle fitment
Gladiator JT coverage runs across the 80th Anniversary, High Altitude, Launch Edition, Mojave, Overland, Rubicon, Sport, Sport S, Willys and Willys Sport trims, all from 2020 to 2022.
Only the Gladiator JT from 2020 through 2022 is listed here, so Wrangler models are not included. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because shocks are not included, the existing shocks need to be checked for length at the new height. Standard suspension kits also change the alignment, so the front end should be re-set after the install.
What’s included
The package covers the coil spring rear lift components and the standard suspension lift parts. Shocks are not part of the package, so a separate set is needed.
Not included: shocks.
