*Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
* Increased crush for improved bearing retention
* Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and their housings
* Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of a hydrodynamic oil film
