Citroen / Peugeot 2.0L 16v XU10J4 ZRP Connecting Rods

ZRP H-Beam Connecting Rods for the Peugeot 2.0L 16V XU10J4 engine are precision-engineered from premium 4340 high-tensile chromoly steel, designed to deliver exceptional strength, durability, and reliability under extreme performance conditions. Optimized for high RPM operation and motorsport applications, these rods provide an ideal balance between reduced reciprocating mass and structural rigidity. The H-beam profile maximizes strength-to-weight ratio, while the small end features a straight-cut pin design requiring aftermarket pistons. Ribbed reinforcement minimizes distortion under high inertial loads without adding unnecessary weight. Wrist pin bushings are crafted from AMPCO® 18 bronze alloy for superior wear resistance and fatigue strength, with precision radial oil grooves functioning as integrated oil reservoirs for consistent lubrication. All rods undergo multi-stage heat treatment for maximum core strength and dimensional stability, followed by shot peening to relieve residual stresses and improve fatigue life. CNC machining ensures extremely tight tolerances, with center-to-center maintained under 0.001" and machining accuracy up to 0.0002". Bend, twist, and big-end geometry are tightly controlled, optimizing performance and longevity.

Additional machining processes
