I need a single piston from a 4age with the 40mm crank.
Unless I can find a whole set of pistons and rods for the 42mm crank.
I have both cranks, so either of those options will work.

Looking to make the purchase as soon as possible.
Please text/call me at 530-249-4889 for quickest communication.

Thank you,
Garrett

Bought a block about a month ago and these were included. I'll be using different pistons and rods so no use to me.

I have a set of smallport pistons with 20mm pins and 42mm crank size. Complete set of 4.

Not the greatest pictures...


Set of 4 in the upper left.


Slight dome to it.


Bearings and rings are there but I'd recommend new just because. Studs and nuts are also there. Everything looks to be in decent shape.

$60 shipped sound fair?
