SO6621-3 vaevaeina mea mama piston i le ono faasologa: uʻamea lafo uʻamea, uʻamea lafo uʻamea vevela, uʻamea lafo carbide, malleable lafo uʻamea, ductile lafo uʻamea, ma sila. I le 2012 Feterale-Mogul na fausia ai le faasologa lona fitu o mea mama piston, GOE70. O mea e faʻaaogaina ai le martensite matrix structure ma faʻapipiʻi chromium carbide, lea e teteʻe i le punou.

O meafaitino ma numera telefoni e masani ona faʻaaogaina i la matou kamupani:
Numera mea: H9 (GOE13)
Numera mea: H6 (GOE32 U14)
Numera mea: H11 (GOE52 KV1)
Numera mea: H11A (PVD piston mea faavae mama)
Numera mea: H12 (GOE56 KV4)
Numera mea: H17 (GOE65C SMX70 ASL813)
