INA ZC-78551T-9R Engine Timing Set

INA Timing Chain Kit for Ford V8 Applications

INA ZC-78551T-9R is an engine timing set for a wide range of Ford, Mercury, and Lincoln applications with double roller .250 fitment notes. It is built for buyers searching for a Ford F-150 timing chain kit, Ford Mustang timing set, or Explorer timing chain replacement with OE-style coverage.

Key Features

• Engine timing set for valve train service
• Includes the essential timing chain components needed for a complete repair
• Kit content may include chains, tensioners, guides, and, in some applications, gears and sprockets
• Includes a specially formulated chain additive from Liqui Moly for Schaeffler applications
• Chain additive is formulated to reduce friction during break-in and lower run-in wear
• Part number: ZC-78551T-9R

Detailed Description

INA timing chain kits are assembled to support a proper timing system repair on Ford, Mercury, and Lincoln engines listed below. The ZC-78551T-9R timing set is referenced for 1972-2001 applications and is listed with double roller .250 notes across the fitment range. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

For shoppers comparing a Ford Explorer timing chain kit, Mercury Mountaineer timing set, or Ford Bronco engine timing set, this INA kit provides the core components commonly replaced during timing service. The included additive is used during initial operation to reduce friction and help limit wear as the chain system breaks in.

What It Helps Fix

• Timing chain noise from worn chain components
• Excessive slack in the timing drive
• Guide or tensioner wear in the valve train
• Timing-related drivability issues caused by stretched chain components
• Service needs on high-mileage Ford F-150, Mustang, and Explorer engines

Installation Notes

Verify engine configuration and timing cover access before installation. Confirm the double roller .250 application note against the vehicle and engine code, and follow factory timing marks and service procedures during assembly. Replace related wear items only after inspecting the full timing system and confirm proper oiling before startup. Part number ZC-78551T-9R should be matched to the exact application listed in the fitment data.

Quality Assurance

INA timing chain kits are built with the components needed for a complete timing repair, and the included additive is formulated to reduce break-in friction and run-in wear. This part is listed for compatible Ford, Mercury, and Lincoln applications including Ford F-150, Ford Mustang, and Ford Explorer models across the stated years.
