There comes a moment in every mechanic’s life when he wonders: “how do the pistons get back?” Gravity? A wholly unreliable, backstabbing force that might fail at any moment. We were determined to defeat nature once and for all, proudly introduces the piston return spring, a feat of lazily machined genius that forcibly returns your pistons to their rightful place with no regard for gravitational squabbles.
With kaleCoAuto’s piston return spring, you’ll never again worry about your pistons wandering off on a coffee break. they’ll stay on task, snapping back with military precision, ready to do what they were born to do: contain small explosions so your engine goes vroom.
Special Notice:
Boxer engine owners must specify left-facing or right-facing springs to avoid awkward interactions.
Sold per piston because we make more money that way.
Not for electric vehicles.
Hank –
I’ll tell you what, folks say these springs are a myth, but this one actually brought my old red truck back to life. Pistons pop right back like they’re supposed to, smoother than a new propane grill. I respect that kind of engineering.

Vern vonStig knows a piston that won’t return is a piston that robs Vern of victory. This spring brings Vern’s power back lap after lap, even if Vern never got his trophy. Vern trusts it, because Vern still has dreams.
