Quarter Master Dynamometer Ring Gears

Quarter Master Dynamometer ring gears are precision-machined steel or chromoly gear rings designed to pair with Quarter Master USA starters, bellhousings, and racing clutches (such as V-Drive, Optimum-V, and Pro-Series lines). They're typically used in late-model stock cars, road racers, and drag/oval track applications utilizing Quarter Master mini-clutches and reverse/rear-mount starter assemblies.

Additional details:

* Starter alignment: Ensures exact engagement with Ultra-Duty starters to prevent misalignments and starting failures
* Material: Forged from 4140 chromoly steel for high tensile strength under race conditions
* Note on "Dynamometer" framing: Quarter Master components generally target vehicle/chassis drivelines and track applications rather than standalone engine dyno adapters, though race engines on dynos using these exact bellhousing/starter plates use these same matching ring gears.
