Product Details

INA timing chain kits are assembled to cover the essential wear items in a timing service, helping restore proper chain control and timing accuracy. In certain applications, the kit also includes gears and sprockets, along with a high-performance chain additive formulated for Schaeffler by Liqui Moly to reduce friction during break-in and lower run-in wear. This makes ZC-73180 a practical choice for technicians servicing compatible Chevrolet C3500, Chevrolet K3500, GMC K3500, and GMC P3500 engines in the listed naval-use configurations. This part cross-references Monroe Shocks & Struts (e.g., 5591200100) for the same application.
