Design & Performance Details:

Factory sway bars are often a compromise between comfort and performance. The STILLEN Adjustable Front Sway Bar increases roll resistance while maintaining predictable steering feel. By retaining a near-OE outer diameter and increasing wall thickness, STILLEN achieves a stiffer rate without the downsides of oversized bars.

The five-position adjustability allows drivers to fine-tune front-end grip and turn-in response based on driving style, tire selection, and suspension setup. This flexibility makes the sway bar suitable for daily driving, spirited canyon runs, and track use.

Factory-style bushing collars are retained to prevent lateral movement of the bar during aggressive cornering, ensuring consistent handling and long-term reliability.

• Factory Front Sway Bar: 640 lbs at 1 inch of travel

Manufacturing & Quality:

Manufactured in-house at STILLEN’s Costa Mesa, California facility, each sway bar undergoes strict quality control from raw material selection through final packaging. A durable red powdercoated finish provides corrosion protection and a clean performance appearance.
