Overview
The Rubicon Express TJ/LJ 3.5 inch Super-Flex adjustable upper and fixed lower system is a complete suspension for TJ and LJ Wranglers that keep factory short arm geometry. It combines flexibility and handling and uses twin tube shocks.
The package includes eight new control arms, with adjustable upper arms at the front and rear fitted with serviceable Super-Flex spherical ball joints. It also has an adjustable front track bar, 3.5-inch lift springs, extended bump stops, longer front stainless steel brake lines and Gen II sway bar disconnects. This version uses the twin tube shock design named in the title.
Key features
- Eight new control arms

- Replacement 3.5-inch lift springs

Choosing a 3.5-inch system
A 3.5-inch lift changes ride height, the angle of the control arms and the length the shocks have to cover. A complete system with matched springs and arms keeps those changes consistent, which is easier to set up than mixing parts from different sources. The brake lines and sway bar disconnects must reach the new positions without strain.
Plan for an alignment and a steering check once the system is in. Recheck the bump stops and shock mounts after the first drives, since the new geometry can shift how they load. Keep a record of the torque on each fastener so future service is straightforward.
- Plan an alignment after the lift is set
- Recheck steering stops and the front track bar setting
- Inspect bump stops for wear over time
