Set of 8 MAHLE Coated Pistons, brand new, with Factory Pre-Installed Rings included (21:1 PISTONS).
MAHLE is the OEM (Original Equipment Manufacturer) for GM.
Compatible with all GM 6.5L V8 Turbo and non-Turbo DIESEL Engines from 1992 to 2002, VIN: F, S, Y, P, and 3 (8th character of VIN#).
These Pistons are compatible with applications including all Pickup Trucks, Vans, and H-1 Hummer from 1992 to 2002.
THESE PISTONS HAVE A FACTORY APPLIED HARD ANODIZED CROWN (TOP) TO ADD DURABILITY AND PREVENT CARBON BUILD-UP.
All Automotive 6.5 applications use a 21:1 compression ratio.
Both turbo and non-turbo use the same pistons and compression ratio from the GM factory.

MAHLE Piston Rings: 1.
All three rings that MAHLE/CLEVITE uses on their aftermarket loaded pistons are truly unique and are without a doubt, these ring-sets are the absolute best in the business.
The top rings are high strength steel with high velocity Moly impregnation.
They are an ideal mix of metals because the steel provides superior durability while the Moly facing provides a hard surface that allows superior compression sealing.
4.
The second ring (middle of piston) is your second line of defense for sealing compression from above and oil from below the piston.
The high strength steel composition of this ring is ideally suited for both of these critical purposes.
5.
The oil ring (bottom ring) is completely unique to MAHLE CLEVITE.
These rings have been improved further by adding a nitrite coating and a chrome finish.
