Peugeot 2.0L EW10J4RS H-Beam Connecting Rods – Supplied with ARP L19 Bolts

Peugeot 2.0L EW10J4RS H-Beam Connecting Rods are manufactured from 4340 high tensile steel and are designed for high performance and extreme durability. This design combines lightweight efficiency with proven reliability at extended RPM ranges, making them suitable for high-output naturally aspirated and forced induction applications.

The bushings are manufactured from Aluminum–Silicon Bronze material and incorporate a radial oil groove that acts as an oil reservoir, improving lubrication under high load conditions.

These rods feature a “Ribbed Pin End” design that minimizes pin-end distortion under heavy inertial loads while reducing unnecessary mass. Each rod is shot peened to relieve material stress and multi-stage heat treated to increase rigidity and structural stability. Tight production tolerances ensure perfect fitment and optimized oil clearances, while bend and twist are strictly controlled.

Each rod is supplied with ARP L19 cap fasteners rated at 260,000 psi, providing superior clamping force and extreme strength for high boost and high RPM applications. The complete kit includes ARP moly lubricant and full installation instructions.
