The GPM FL054TS rear main gear is manufactured from #45 hardened steel to deliver consistent wear resistance in demanding running conditions. Its 54 tooth profile is specified to provide steady meshing and to reduce concentrated stress on mating components.
The FL054TS design balances tooth count and hardness to maintain smooth torque transfer while minimising premature wear on adjacent drivetrain parts.
Fitting the FL054TS requires the included stainless steel cap head screw to secure the gear to the shaft, ensuring reliable retention during high load operation.
