ZRP Connecting Rods M5 V8 S63B44 HD Series

The I-Beam Connecting rods for BMW V8 engine M3 S65 4.0L are built from the finest raw materials 4340 high tensile steel with a specially optimized shape for high performance and extreme durability.

These feature “straight cut” pin end for increased durability, so they can only be used in conjunction with aftermarket pistons. The bushings are made from AMPCO 18 material, for excellent resistance to wear and fatigue and have radial groove acting as an oil reservoir. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. The tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances. Bend and twist is tightly controlled.

Each rod includes ARP 2000 cap fasteners that are rated at 220,000psi.
