PRODUCT DESCRIPTION
Product details
The Honda F20 H-Beam connecting rods are made from high-strength 4340 steel and designed for high performance and extreme durability. This ultralight design combines lightweight performance with proven reliability at high RPMs. These connecting rods have a tapered pin end, making them compatible with OEM pistons. 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 pin end distortion under high inertial loads while reducing weight. They undergo shot peening to relieve material stress and multi-stage heat treatment to increase rigidity. Strict tolerances in the production process ensure a perfect fit and optimize oil clearances. Flex and torsion are strictly controlled. Each connecting rod includes ARP 2000 head bolts with a tensile strength of 220,000 psi. Optionally, ARP L19 material with 260,000 psi can be purchased as an upgrade. The complete kit includes ARP moly lubricant and comprehensive assembly instructions.
Additional Machining Processes:
Tapered pin end: also suitable for OEM pistons.
Dowel pin bushings for a perfect fit and precise reassembly.
Flanged cap recess for enhanced big end integrity in extreme applications.
Thrust face grooves to reduce weight.
