SPEEDWERX - Straight-Up USA Horsepower since 1994
 
The roots of Speedwerx go back to the 80’s and 90’s, when owner Steve Houle was designing and building parts for his own race sleds. His innovative ideas spoke for themselves as he proved to be a dominating force in snowmobile racing, winning many races and multiple world championships along the way. Soon other competitors and consumers were asking for their own race-proven parts, and that led to the creation of the Hot Seat Performance brand in 1994, and the Speedwerx brand in 1999.
 
For over 25 years, the Speedwerx family has been committed to winning. Whether it is on the race track with our own machines, or helping our customers achieve their goals with our products, Speedwerx is a proven winner in many different racing disciplines including Snowmobiles, ATV’s, UTV’s, PWC’s, and Dirt Track Racing Cars. With 183+ World and National titles, 31 X-Games Medals (15 Gold!), and Thousands of trips to Victory Lane, Speedwerx is known and respected worldwide as an industry icon that sets the bar when it comes to performance, quality, and service.

The staff here at Speedwerx takes pride in our work and the products we manufacture. Most of our products are made right here in the USA and we feel that this is as important to our customers as it is to us. Our products are designed to perform in the toughest and most demanding conditions and are thoroughly tested with thousands of laps on the track and thousands of miles on the trails and in the backcountry every year. If you’re searching for the best performing and highest quality parts for your Arctic Cat, Polaris, or Ski-Doo Snowmobile, ATV, UTV, or your Dirt Track Race Car, look no further than Speedwerx.
