Circle Track valvetrain components are one of the foundational products at PAC Racing. We offer several lines of springs dedicated to circle track racing with class-specific offerings for 602, 604, and RaceSaver options.

Outside of those, we offer our 1200 Series Single, 1200 Series Dual, 1300 Series Dual, and 1500 Series Dual, and many of those with a damper option. Circle track springs also work well in applications more focused on endurance including road racing, off-road racing, and marine applications.
