RIBBED PIN END

Ribbed pin end surround helps to maintain pin bore roundness and avoid PE distortion in high engine speed applications

ALUM/SIL BRONZE BUSHING

All ZRP rod bushings are made from Aluminum-silicon-bronze alloy providing integrity and reliability.

DOUBLE RIBBED CAP

Double ribbed caps for added strength and better alignment providing bearing caps precision.

LIPPED CAP RELIEF

Big – end rigidity improvement using bigger contact area between cap and connecting rod body, maintaining the least possible weight.

RADIAL GROOVE BUSHING

Rod bushings from aluminum silicon bronze with radial groove for oil reservoir and better pin oiling.

DUAL OIL P.E. RESERVOIR

Double oil reservoirs on different angle depending on the application for maximum pin oiling.

GROOVE IN THRUST FACE

All ZRP rods come with grooves in thrust face, feature that allows weight reduction and reduced friction.

H-BEAM SHAPE

H-Beam design providing extended rigidity under vertical load. The best selling option when it comes to forged connecting rods.

I-BEAM TAPERED

The tapered I-beam rods are designed to spread loads more evenly, to increase load capacity, while maintaining a low weight and increased piston clearance.

OIL RESERVOIR ON P.E

Featuring a funnel shape at the top oil hole to provide a better chance to collect oil for the PE lubrication.

RIFLE DRILLED

This feature provides better pin oiling and cooling leading to increased longevity of the whole piston-rod set.

TAPERED P.E

Tapered pin end feature allows weight saving and increased clearance when using boxed pistons.
