ZRP RODS – CONNECTING RODS SET BMW M30B28 / M30B30 / M30B32 / M30B35 I-BEAM

The I-Beam connecting rods for BMW M30 engines are manufactured from the finest raw materials, high-strength 4340 steel, with a specially optimized shape for high performance and extreme durability. The bushings are made of AMPCO 18 material for excellent wear and fatigue resistance and have a radial groove that serves as an oil reservoir. They are shot-peened to relieve material stress and multi-stage heat treated to increase rigidity. Tight manufacturing tolerances ensure a perfect fit while optimizing oil clearances. Bending and torsion are strictly controlled. Each connecting rod includes ARP 2000 plug fasteners rated at 220,000 psi, with optional ARP L19 material rated at 260,000 psi available as an upgrade. The entire kit comes with ARP moly and complete installation instructions.
