Painless Performance Products - Since 1990


After 30 years in business, we are continuously impressed by America’s love affair with the automobile. Even in the midst of this terrible pandemic, it would seem that many of you are using this unplanned downtime to finish up work on that project vehicle, so much so that our plant is working overtime to keep up with your orders. Web traffic and call volume are at record levels. We greatly appreciate your loyal support of Painless Performance Products.

It won’t be long before racing and car shows are once again a part of our regular lives. All of us at Painless are looking forward to hitting the road again to thank you in person. Until that day comes, we pray you all stay safe and well. In the meantime, please feel free to visit our Facebook page and post pictures of your latest project. We’d really like to know.
