{"product_id":"4340-chrome-moly-connecting-rod-set-84mm-bore","title":"4340 Chrome Moly Connecting Rod Set (84mm+ Bore)","description":"Constructed from vacuum-drawn 4340 Chrome Moly steel using a 2-piece forging process, these rods are subjected to a multi-stage heat treatment to maximize fatigue strength and ensure dimensional stability, keeping big-end bores round for the life of the bearings. The optimized H-beam design, validated through CAD drafting and FEA analysis, provides an excellent strength-to-weight ratio for powerful, high-RPM European engines.\n\nThese specialized connecting rods are designed for 84mm+ bore sizes, commonly found in VW R32 VR6 engines, and utilize stronger ARP 3\/8\" rod bolts. Each set is finish machined and honed in the USA, with tolerances as tight as .0003\" ground on Sunnen brand equipment, resulting in industry-leading low failure rates. The rods feature generous wrist pin oiling and optional rifle drilling. They are Magnaflux and dimensionally inspected, and all rods in the set are packed in balanced sets within +\/- 1 gram. These rods have been combination tested to support over 700+ BHP and have even been used in four-cylinder builds exceeding 800+ BHP.\n\nWhile the product page indicates that this specific item does not currently have vehicle applications listed and advises contacting their sales team for fitment verification, the general application for these rods is stated to be ALL VW \/ Audi VR6 Engines \u0026amp; 10V VR5 with 84mm+ bore.
