Choose options to add HD H13 Wrist Pins or no pins.
Choose Ring Stack Options for:
-M2 Tooled Steel top ring with a gapless second ring.
(The M2 Tooled Steel top ring is highly recommended for any applications that are seeing over 40 PSI of boost)
-APSS (Stainless Steel) top ring with a gapless second ring.
(The APSS top ring is only recommended for lower horsepower builds that will be driven often. This is a softer ring for superior longevity.)
