ZRP L19 Connecting Rods for Ford Duratec 2.0L 16v

Ford 2.0L Duratec H-Beam connecting rods are made from high-strength 4340 steel and designed for high performance and extreme durability. This design combines lightness with proven reliability at high RPMs. The bushings are made from aluminum-silicon/bronze and feature a radial groove that acts as an oil reservoir. These connecting rods have a grooved pin end that minimizes deformation under high inertial loads while reducing weight. They are shot-peened to relieve material stress and multi-stage heat-treated to increase rigidity. Strict tolerances in the production process ensure a perfect fit and optimize oil clearances. Flex and twist are strictly controlled.

Each connecting rod includes ARP 2000 hex head bolts with a tensile strength of 220,000 psi. Optionally, ARP L19 bolts with 260,000 psi can be chosen. The complete kit is supplied with ARP moly lubricant and full assembly instructions.
