High Performance Parts:

You could say high performance is in our blood. Our founder Steve Millen enjoyed a multi-decade racing career with many notable wins. He started STILLEN out of necessity. He couldn't find parts that would withstand the rigors of racing, so he started machining his own. Other drivers took notice and wanted their own Steve Millen parts. The rest, as they say, is history.

Fast forward 30 years, and Steve's standards for design, durability and precision still represent the core of the STILLEN high performance philosophy:

We'll make it ourselves
Or we'll find someone who makes it the way we would
Or we won't sell it.

It's a different approach than selling anything for autos, but we're comfortable with that.

We're confident you will be too.
