Evo 123 - Carrillo - 4G63 Pro-H Connecting Rods (3/8 CARR Bolt) - 6-Bolt
Carrillo Pro-H connecting rods, 3/8 CARR bolt — 6-bolt 4G63
The Pro-H beam is Carrillo's all-rounder, but the reason to pick this listing over the other Pro-H set is the bolt. The 3/8 CARR is a multiphase MP35N fastener at roughly 285,000 psi ultimate tensile strength, and on a rod the bolt is what fails first when an engine is revved hard and asked to hold big cylinder pressure lap after lap. Choose this version when the build is aimed at the top of the power range or at sustained high RPM, and the standard fastener no longer leaves you comfortable margin. Set of four, forged and fully machined.
