Overview
The TeraFlex 1156223 is a 3-inch lift suspension system for the 2007–2018 Jeep Wrangler (JK) 2-door. It includes four preset Sport flexarms and a track bar. The front lower and rear upper arms are Sport flexarms.

Key features
- Four preset Sport flexarms
- Front lower and rear upper Sport flexarms
- Track bar included
- Suspension geometry and load tuning that keep the factory stability controls working
Before you buy
A 3-inch lift changes the suspension geometry, ride height and how the vehicle loads its springs, so shock selection matters. Shocks should be chosen to match the new ride height and the spring rates in use, since a shock that is too short or too soft can bottom out or wear quickly. Check the shock length and mounting points before buying replacements.
Owners of Wrangler JK 2-door models often pair a lift with larger tires, which adds rotating weight and can affect steering. Check the steering components, tie rod ends and driveline joints after any tire change. Look for uneven tire wear, drift on the road or noise over bumps, since these can show that a component has been overloaded or has shifted out of position.
- Shock length for the new ride height
- Driveline angles after the lift
- Brake line length after installation
