ZRP RODS – MITSUBISHI 2.0L 4G63 / 4G63T H-BEAM CONNECTING RODS SET

I-Beam connecting rods for the BMW M50/M52 engine series are manufactured from the finest raw materials, 4340 high-strength steel, with a specially optimized shape for high performance and extreme durability. The bushings are made from 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 stress from the material and multi-stage heat treated to increase rigidity. Tight manufacturing tolerances ensure a perfect fit while optimizing oil clearances. Bend and twist are tightly controlled. Each 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, and the entire kit comes with ARP moly and complete installation instructions.
