PISTON PINS

How do I know my piston to wall clearance, and where do I get the measurement?

By Li Chenyu / hcfire360 November

All Piston kits include a piston spec sheet with a piston to wall clearance recommendation. Always measure Pistons at the recommended gauge point, usually .500" up from the bottom of the skirt or where otherwise indicated on the spec sheet. Subtract this dimension from your finished bore size to determine your piston-to-wall clearance. If you have questions, please contact our customer center.
Q6. What material does TAKUMI use to make the piston Pins?
TAKUMI uses high quality steel in all of its piston pins.
