-Bronze attracts oil and improves wrist pin lubrication. Eliminates pin galling and maximizes wrist pin life.
-Precision located to maximize lower rod oiling and extend bearing life
-Dimpled design increases oil retention and reduces friction between rod, washer, and crank web

Gaskets & Seal Features:
-Manufactured from premium materials
-Exceed OEM standards, and provide exceptional seal between critical mating surfaces

Bearing Features:
-Precision ground bearings
-Manufactured to the highest quality standards. Case hardened for maximum life and smooth operation at high RPM's

Piston Features:
-Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.
