Detailed Description

The MRK-654 is intended for stock engine service where a complete rocker arm solution is needed for the listed Ford applications. Melling packages the rocker arm with the correct fulcrum, bolt, and stud combinations to simplify parts selection for the engine build. This part cross-references Monroe Shocks & Struts (e.g., 41-2710, R-948) for the same application.

For Ford E-150 Econoline, F-150, and Bronco service work, the MRK-654 provides a direct-fit valve train component set for the covered years and stock configurations. The stainless steel construction and adjustable, non-roller design make it a practical choice for replacement work on these Ford engine applications.

What It Is Used For
