Gorilla rocker arm kit designed for Twin Cam engines. The arms are precision ground from 4140HT steel, then nitrided and surface treated to optimise contact hardness. The kit also includes eight ARP bolt kits, assembled and provided for complete installation.
This kit is aimed at riders looking for robust engine parts suitable for demanding configurations — vintage/classic restoration or touring. Suitable for recent Twin Cam models and particularly relevant for Harley-Davidson equipped with high lift camshafts. Check compatibility with your machine and cylinder head type before installation.
