For nearly two decades Speedtech Performance has been a leader and innovator in providing forward thinking suspension and LS/T56 swap components. Most recently, re-inventing suspension design and performance through the ExtReme line of prod- ucts. Through race bred engineering and development, Speedtech parts turn average muscle cars into cool cruisers with late model like reflexes and race car level handling. Couple that with a history of building show and race event winning street machines and you’ve got a proven recipe that translates to the same success for you and your project. Located in the south western corner of Utah, Speedtech is dedicated to providing genuine USA made products that are stronger, better engineered, and out perform anything else available. All of this is started with the in-house design and engineering team and backed with the best customer service in the industry. In spring 2019, Speedtech moved to a new location with over 30,000 square feet of manufacturing and warehouse; all sitting on 4 acres of land. 4160 S. River Road, St. George, UT 84790
