JK: Forged ST Sway Bar Kit - Rear.
- - The TeraFlex JK Forged Rear ST Sway Bar is designed to provide trail-tuned torsion resistance without limiting suspension flex or sacrificing highway drivability and side-hill off-camber stability.
- - A slight increase over factory torsion resistance provides added side hill and highway stability
- - Secure arm clamping with two 12mm bolts providing 27,000 lbs. of clamping force to prevent bar splines from loosening over time
- - Simple bolt-on installation, no modifications required
Fitment and Installation Notes
- - All Factory axles require wheels with a maximum backspacing of 4.75" or wheel adapters
- - May require trimming of fender liners depending on aftermarket modifications

JK: Forged ST Sway Bar Kit - Rear.
The TeraFlex Forged Rear ST Sway Bar is specifically engineered to complement the TeraFlex Long Arm, Falcon Shock Coilover Suspension, while remaining compatible with all Jk Wranglers with a minimum 1-inch suspension lift. For overland-ready Jeeps seeking improved stability and reduced body roll, the ST Sway Bar will make a noticeable improvement. Conversely, Jeeps built for crawling the boulders can maximize suspension flex as the vehicle easily overcomes the torsion resistance of the sway bar.
Compatible with factory width axles* and those 70 inches and wider, the JK TeraFlex ST Sway Bar accommodates various suspension systems regardless of brand. The TeraFlex Rear ST Sway Bar provides a direct bolt up, maintenance-free solution for enhanced stability and flex. The TeraFlex JK Forged Rear ST Sway Bar is designed to provide trail-tuned torsion resistance without limiting suspension flex or sacrificing highway drivability and side-hill off-camber stability.
