FEULING PARTS - One-Piece Rocker Arms (ref. 4072)
Designed for demanding builds and installations on Harley engine bases, these one-piece rocker arms replace the original parts while maintaining the manufacturer's length. Made from 4130 chromoly, reinforced tubular material, they provide a robust solution to limit issues related to hydraulic lifters and preserve the maximum lift of the camshaft.
Installation: requires the removal of the cylinder head covers and rockers to install the rods. These parts are intended for the Vintage/Classic and Touring categories — ideal for those seeking reliability and lift retention without height adjustment.
Common applications: suitable for various Harley-Davidson models listed as references (e.g. FXDLS, FLSTFBS, FLSS 2017 - 1800 cc). Manufacturer reference: 4072.
