DRAG SPECIALTIES Engine Motor Mounts, Breathers & Service Hardware are engineered to accommodate the four rocker arm shafts of 1966‑1984 Shovelhead engines. The kit includes shims, spacers, and seals that allow the rocker arms to be rebuilt without the need for re‑shimming or adjustment, ensuring a precise and repeatable valve job.
These components are designed for single‑use replacement during each valve service. When the valve job is complete, the hardware can be removed and replaced again for the next maintenance cycle, providing a reliable and straightforward solution for Shovelhead engine maintenance.
