Lipped Cap and Lipped Cap Relief for improved big-end integrity at extreme applications. This is achieved with a small increase in the contact areas of the cap and the connecting rod

BE Oil Squirters optimal for engines without oil squirters to facilitate cooling and lubrication processes.

Tapered Pin End for weight reduction or piston design.

Custom Laser Mark/Serialization for ordering your own custom logo or ad special  dimensions /specifications of accompanying parts (bolts/other kit parts etc) for easy reference on the ZRP rods.

Grooves in Thrust Face for weight reduction

Forced Pin Oiling offer greater life duration for the rods. This is achieved by the installation of a slot behind the bearing and a hole through the center of the rod thus establishing a reservoir that  supplies oil underneath the wrist pin ,when the connecting rods is pulling mass down the cylinder for better lubrication, Oil Reservoir on Pin End for improved oil collection at the Pin End lubrication stage.
