Design & Performance Details:

Factory sway bars are often undersized, limiting overall handling potential. The STILLEN Adjustable Rear Sway Bar increases roll resistance while maintaining predictable handling characteristics, allowing the tires to maintain better contact with the road surface during aggressive cornering.

The three-position adjustability enables fine-tuning of rear stiffness, making this kit ideal for drivers who want to dial in handling balance for street, canyon, or track driving. Most drivers will find optimal performance with a moderate stiffness increase, while advanced users can further sharpen turn-in and rotation as desired.

Constructed from aircraft-grade steel, the bar offers exceptional torsional strength and long-term durability under high load conditions.

Manufacturing & Quality:

STILLEN has designed and manufactured sway bars in-house for over 20 years and also supplies sway bars for major suspension brands in the industry. Every sway bar is precision-formed, heat-treated, and finished to ensure consistent performance and reliability.

Upgrade your suspension system with the STILLEN Adjustable Rear Sway Bar Kit [304365] and experience improved cornering confidence, reduced body roll, and enhanced handling precision.
