Overview
The Rubicon Express 3.5 Inch Extreme-Duty Long Arm Lift Kit with Rear Track Bar and Twin Tube Shocks (part number RE7213T) is a long arm suspension lift for the Jeep TJ. Its lift height range is 3 to 4.99 inches, and the kit is sold as a 3.5-inch lift.
The kit is a complete suspension replacement that uses longer control arms to improve lifted suspension geometry. The longer arms add stability on and off road, reduce torque roll and improve trail traction compared with a standard short arm lift.
Key features
- Chromoly long control arms
- PT-Meg Super-Ride bushings, designed for on- and off-road performance
- Adjustable control arms with serviceable Super-Flex spherical ball joints
- Tuned lift coil springs
- Rear track bar included
- Twin tube shocks included
- Three-piece belly pan for easy transfer case and transmission access
Setting up long arms
Long arms change the relationship between the axle and the control arms, so the suspension geometry differs from the factory setup. That difference is the reason the alignment and driveline angles have to be checked after the kit is in, since a lift this size changes how the drivetrain works through its travel.
Track bar and shock angles also change with the kit, and the belly pan has to clear the transfer case and transmission at full travel. Setting these items at the end of installation keeps the ride predictable and the steering centered, which matters on long highway runs as well as on the trail.
- Set alignment after the arms are installed
- Check driveline angles at both ends
- Inspect the belly pan for clearance

Vehicle fitment
The kit is built for the Jeep TJ, which is the 1997–2006 Jeep Wrangler (TJ).
The 2007 and newer JK and the JL are not covered by this kit, and neither are the Gladiator or the Cherokee. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
A long arm system replaces the factory control arms and changes the suspension geometry, so the alignment and the driveline angles must be set after installation. Rubicon Express recommends the kit for trail use, and the three-piece belly pan should be checked for clearance once the kit is in.
What’s included
Chromoly long arms with PT-Meg Super-Ride bushings and Super-Flex spherical ball joints, tuned lift coil springs, a rear track bar, twin tube shocks and a three-piece belly pan.
