Replace your rocker shafts with a part designed to last: these Gorilla rocker shafts FEULING PARTS are ground to precision and machined from 4140HT steel, then nitrided and surface treated to enhance wear resistance. Designed for Twin Cam engines, they provide superior rigidity compared to the original shafts and are particularly suitable when equipping the machine with high-lift camshafts and reinforced valve springs.
Whether you are looking to enhance a roadster build, optimise a heavy touring bike, or reinforce a vintage motorcycle ready for the road, these shafts provide strength and durability to the valve trains. Examples of models often equipped: Harley-Davidson FXSE CVO, BUELL XB12XT Ulysses, Harley-Davidson FXDLS Low Rider S. Manufacturer reference: 1235 (FEULING PARTS).
