Straightline Performance is a global manufacturer of performance parts with distribution partners in over 25 countries. Straightline is the only Dynojet Power Commander Tuning Center that is certified for snowmobiles, atvs, and motorcycles. Straightline Performance has the capability to design, develop, test, and manufacture all of its products entirely in-house. This distinguishes Straightline Performance from a large number of performance companies worldwide.

Jason's experience, attention to detail, and commitment to quality have propelled Straightline Performance to prominence as an aftermarket parts supplier over the last 23 years.


Straightline performance is frequently defined in terms of experience, history, and familial relationships. After years of involvement in the snowmobile industry, Jason Houle and his wife Denise founded Straightline Performance in 1997. Jason began snowmobiling when he was two years old, encouraged by his father, Duane, and grandfather, Stu, who were both accomplished snowmobile racers. With a family racing history spanning the 1960's and roots in cross-country, oval track, and drag racing, as well as several world records and racing accomplishments, many believe that "Jason was born with a desire to go fast."

Jason continued the family tradition of racing in the late 1980's, specializing in 1000-foot ice speed runs. He became the first 16-year-old to hold a world speed record in 1992, earning him the N.S.S.R.'s "Rookie of the Year" award (National Straightline Snowmobile Racing). Jason decided to branch out from straightline ice racing in the mid-1990's and pursued other forms of snowmobile racing, including asphalt, water, and grass drag racing. For more than 50 years and three generations, the Houle family's determination to succeed has left an indelible mark on the snowmobiling industry.
