14-21 Q50 / 16-21 Q60 Adjustable Rear Sway Bar by Stillen

A properly matched set of sway bars will really improve the balance of your car or truck and is a great way to fine tune handling. They also play a critical function by generating maximum tire contact with the road surface. The result: major improvement in the joy you get out of hustling your ride through your local canyon roads or on your favorite race track.

Original equipment Sway Bars are often too small for optimum performance. STILLEN anti-roll bars are made from high strength aircraft grade steel for maximum torsional strength and durability. Most drivers will be happiest with a moderate increase in stiffness. An adjustable sway bar offers the versatility to fine tune handling as desired.

STILLEN has been designing and manufacturing sway bars in-house for more than 20 years. We private label manufacture swaybars for some of the largest “suspension manufacturers” in the industry. All STILLEN Sway Bars come complete with quality hardware and installation instructions (when applicable/necessary).
