Made in the USA

These forged pistons are made in USA. I wanted to lower the compression rate from the OEM’s high 11:1 to 9.??:1 to lower the risk of detonation. These are on a little heavy side, but Traum seems the only manufacturer that makes forged pistons with dished top for J32A3. They are not cheap, but as my original motor couldn’t take a few PSI of boost, I needed these. A piston ring clearance chart is included.
