TeraFlex 1790004 Forged ST Rear Sway Bar Kit for Jeep Wrangler JK 5-6 Inch Lift

The TeraFlex 1790004 Forged ST (Street & Trail) Rear Sway Bar Kit is engineered to deliver trail-tuned torsion resistance for 2007–2018 Jeep Wrangler JK models running 5–6 inches of suspension lift. Designed to complement the TeraFlex Long Arm and Falcon Shock Coilover Suspension systems, it is also fully compatible with any JK Wrangler running a minimum 1-inch lift, regardless of suspension brand.

The ST designation stands for Street & Trail — striking a deliberate balance between on-road stability and off-road articulation. For overland-focused builds, the sway bar provides a slight increase over factory torsion resistance for improved side-hill and highway stability with reduced body roll. For rock crawling rigs, suspension flex is maximized as the vehicle easily overcomes sway bar torsion resistance on demanding terrain.

Key Features:

• Forged sway bar arms provide superior resistance to bending and fatigue under extreme loads
• Three adjustable stiffness settings: center hole matches factory rate, outer hole softens by ~10%, inner hole stiffens by ~10%
• Secure arm clamping via two 12mm bolts delivering 27,000 lbs. of clamping force to prevent spline loosening over time
• Teflon-lined rubber bushings maintain factory noise and vibration isolation for a smooth, quiet ride
• Adjustable spacers allow sway bar width tuning to accommodate different tire sizes and fender liner clearance
• Direct bolt-on installation — no welding or cutting required
• Compatible with all engine configurations and both 2-door and 4-door JK Wrangler models
• Fits factory-width axles and those 70 inches and wider
• Factory axles require wheels with a maximum of 4.75-inch backspacing or the use of wheel adapters
• May require fender liner trimming depending on aftermarket modifications
