Specifications

The M‑4312003PR Injector Pin & Roller Kit, provided by McBee‑Interstate McBee and available through Wofford Truck Parts, is designed as a high‑quality replacement for Cummins ISX dual‑cam injector rocker arm assemblies. Engineered and manufactured in ISO 9001:2015 and AAR-certified facilities in the USA, the kit includes precision-machined pins and rollers to restore proper injector motion and prevent premature wear.



This injector kit is ideal for heavy-duty truck engines used in severe-duty, over-the-road applications, offering tight OEM-spec tolerances, smooth cam lobe engagement, and longevity under high-load conditions. McBee’s fuel injection parts are backed by a one-year unlimited mileage warranty specifically for these components, and all engine rebuild parts carry a two-year unlimited mileage warranty. Compatible with Cummins ISX and QSX engines equipped with dual‑cam injector rocker systems, it's a trusted option for fleets, service shops, and rebuild projects.
