The I-Beam Connecting rods for BMW M50/M52 engine series are built from the finest raw materials 4340 high tensile steel with a specially optimized shape for high performance and extreme durability.

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, optional ARP L19 material 260.00psi available as an upgrade and the whole kit is supplied with ARP moly and full fitting instructions.

Application: M20B25 / M50B25 / M52B25 / M50B28 / M52B28 / M54B30 / M52B32 / M52B32

Additional machining processes

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
