The BTR Adjustable Lower Timing Gear starts with the OEM Ford gear for its metallurgy, then adds machined keyways that let the installer offset camshaft timing 4, 6, 8, or 10 degrees — useful for dialing in a camshaft, accounting for a locked phaser, or running a fixed-gear cam conversion on the Ford 7.3L Godzilla engine. The front face of the gear is marked to show which keyway position corresponds to each degree of retard, and the barrel is laser-etched with alignment marks matching the offset keyways.

FAQ
What engine is the BTR-TMGR-GZM lower timing gear designed for?
It is designed for the Ford 7.3L Godzilla engine.
What degree offsets does the BTR-TMGR-GZM allow?
The gear's keyways let installers offset camshaft timing by 4, 6, 8, or 10 degrees to dial in a camshaft, compensate for a locked phaser, or run a fixed-gear cam conversion.
What material is the BTR-TMGR-GZM gear made from?
BTR starts with the OEM Ford gear for its metallurgy, then machines in the offset keyways and laser-etches the alignment marks.
How do I know which keyway to use during installation?
The front face of the gear is marked to show which keyway corresponds to each degree of retard, and the barrel is laser-etched with alignment marks — follow the engine manufacturer's timing set installation guidelines, then index to the marks for the desired offset.
