OEM 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).

Dropped off my 2022 Subaru WRX for Exhaust, spoiler, aeroflow dynamic kit, and they killed it. Quality work and amazing customer service. Speedzone gets you right.

They gave me the best price I could find after shopping around for a while. They are well informed and familiar with the products they sell, great communication and quick responses. I would no doubt purchase from them again. Solid company. Recommended. A+

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
