The H-shaped ZRP forged connecting rods for the Peugeot 206 RC 2.0 L 16V with EW10J4S (RFK) engine are designed for engine tuning applications requiring mechanical resistance and high-RPM durability. Manufactured from high-strength 4340 steel, they feature a center distance of 139 mm and accommodate 21 mm gudgeon pins.
Their ribbed connecting rod small end minimizes deformation under inertial forces while keeping weight in check. The bushings feature a radial groove that serves as an oil reservoir. The set of 4 connecting rods (R-PEU-003H) includes 3/8" ARP2000 fasteners, ARP mounting lubricant, and instructions.

- Bending and torsion testing: verification of geometry.
- Finite element analysis: computer-aided stress analysis.
Mounting on EW10J4S engine
Before assembly, verify that the pistons, shafts, bearings, and crankpins match the sizes of the connecting rods. Check the operating clearances and clearance between moving parts. Follow the oiling and tightening instructions for the supplied ARP2000 fasteners.
