ZRP RODS – BMW / MINI 2.0L N20 I-BEAM CONNECTING RODS SET

The I-Beam Series “Heavy Duty” connecting rods for the Honda B18C are designed for high-horsepower/boost applications. They are constructed from the finest raw materials, high-strength 4340-EN24T steel, with a specially optimized shape for high performance and extreme durability. The CC length has been increased by 5.00 mm to make these rods ideal for long-rod applications. The bushings are made from aluminum/silicon/bronze alloy and have a radial oil reservoir groove. 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 3/8″ plug fasteners rated at 220,000 psi. Optional ARP L19 260,000 psi material is available as an upgrade. The entire kit comes with ARP moly and complete assembly instructions.
