Peugeot 2.0L EW10J4RS H-Beam Connecting Rods

Manufactured from 4340 high tensile steel, these connecting rods are designed for high performance and extreme durability. The design combines lightweight performance with proven reliability at extended rpm. The bushings are made from aluminum-silicon/bronze material with a radial groove acting as an oil reservoir. Featuring a "Ribbed pin end," these rods minimize pin end distortion under heavy inertial loads while saving excess weight. They are shot peened to relieve stress and multi-stage heat treated to increase rigidity. Tight tolerances in the production process ensure perfect fitment while optimizing oil clearances. Bend and twist are tightly controlled. Each rod includes ARP 2000 cap fasteners rated at 220,000 psi, with optional ARP L19 material rated at 260,000 psi available as an upgrade. The kit is supplied with ARP moly and full fitting instructions.

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
