Design & Performance Details:

A properly tuned rear sway bar plays a critical role in optimizing vehicle balance and maximizing tire contact with the road. Factory rear sway bars are typically undersized, limiting the car’s ability to remain composed during aggressive cornering. The STILLEN Adjustable Rear Sway Bar increases roll stiffness to improve rear-end control while reducing excessive body movement.

With three adjustment positions, drivers can fine tune rear roll stiffness to suit driving style, tire setup, or suspension modifications. This adjustability allows improved turn-in response while maintaining predictable and stable handling characteristics for both street and track applications.

Constructed from high-strength aircraft-grade steel, the bar provides exceptional torsional rigidity and long-term durability. The powdercoated finish protects against corrosion while delivering a clean, performance-oriented appearance.

Manufacturing & Quality:

STILLEN has been designing and manufacturing sway bars in-house for over 20 years. Produced at STILLEN’s Costa Mesa, California facility, each sway bar undergoes strict quality control from material selection through final assembly. STILLEN also private-label manufactures sway bars for some of the largest suspension manufacturers in the industry.

Each kit includes quality hardware and installation instructions where applicable, ensuring a precise fit and reliable performance.
