Description

The I-Beam Connecting rods for BMW 3.0L N54 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 L19 cap fasteners that are rated at 260,000psi and the whole kit is supplied with ARP moly and full fitting instructions.

Additional machining processes

• “Straight Cut” Pin End - Suitable for aftermarket pistons
• Dowel sleeves for perfect fit and accurate re-assembling
• Lipped Cap Relief for improved big-end integrity at extreme application
• Grooves in Thrust Face for weight reduction

Technical Features of ZRP Connecting Rods
