Took my engine apart today and noticed the pistons were screamin' eagle. I was hoping someone could help me out.
1992 FXRS-CONV

 

Screamin Eagle forged pistons are made by Arias Pistons here in So Cal, not sure who makes the cast ones though, probably Ertle.

 

not all the forged SE pistons are arias. the SE 110 forged 10.5 to 1's i ordered wre made by MAHLE. my 95 inch SE forged 10.5 to 1's were made by arias though.

 

The 9.6:1 SE 3 7\8 pistons for my 95" are no longer Aries and the part number superseded. I don't know why H-D switched suppliers. Probably Arias got underbid. Don't know who makes 'em now but, just might order mine from Arias direct.
