TOMEI CONROD BOLT SET MITSUBISHI EVO 4G63

Extreme engine speeds with the increase of cylinder pressure and power will add an increased burden on the conrod bolts. The increased stroke length in most performance engines and increased piston speeds will also add more stress loads to the conrod bolts. Since the common weak points of the connecting rods are usually the conrod bolts itself. Upgrading the conrod bolts to a stronger type will usually resolves most problems by greatly increasing the reliability of the connecting rod without having had to spend more on a complete conrod set. These conrod bolts are designed and made by forged SCM440 material followed but additional surface heat treatment for added strengthening.
