Detailed Product Overview

Ring gear teeth take repeated contact from the starter motor every time the engine starts. Over time, that repeated engagement can wear down or break the teeth, leading to starting problems and the need for replacement. The Pioneer Cables FRG-155FT is engineered to match the original part’s fit and function, helping restore proper starter-to-ring-gear engagement in Ford F-250, Ford F-350, and Ford E-Series applications. This part cross-references 155FT and FM155FT for the same application.

Common Problems This Part Addresses

• Starter motor engagement noise caused by worn ring gear teeth
• Engine cranking issues from broken or damaged teeth
• Intermittent starting caused by inconsistent starter-to-gear contact
• Transmission service needs after ring gear wear
• Restoration of proper starter engagement on Ford truck and van applications

Installation Notes and Tips

Verify tooth count, outside diameter, and inside diameter before installation to confirm the correct application. Inspect the starter drive and related components at the same time, since worn starter parts can accelerate ring gear damage. Proper alignment and installation procedures are important for reliable operation on Ford F-250, Ford F-350, and E-Series vehicles.
