.531 ID Distributor Gear Melonized - Ford

The .531 ID Distributor Gear Melonized - Ford by COMP CAMS is a precision-engineered timing component designed for Ford engine builders and performance enthusiasts who demand reliability in high-rpm applications. This small but critical gear sits at the heart of your distributor assembly, orchestrating ignition timing through direct engagement with the camshaft drive. Whether you're rebuilding a stock 5.0L or fine-tuning a modified big-block, a quality distributor gear ensures repeatable, accurate spark delivery across the entire rpm range.

COMP CAMS' melonized finish on this .531 inch inside diameter gear provides superior wear resistance and reduced friction compared to standard cast iron alternatives. The melonizing process creates a hard, self-lubricating surface that withstands thousands of hours of constant meshing without rapid degradation—critical in racing or street performance builds where distributor shaft wear translates directly to timing drift. The precisely machined teeth ensure minimal backlash and smooth power transfer, maintaining distributor synchronization even under sustained load or aggressive throttle transitions.

Ford small-block and big-block engine builders rely on this gear when installing aftermarket or OEM distributor assemblies in carbureted, fuel-injected, or turbocharged applications. The .531 ID specification matches COMP CAMS distributor shafts and compatible Ford racing distributors; verify your distributor's shaft diameter before ordering. This gear is essential for achieving optimal performance and reliability in various engine setups.
