38-14M-55 HTD Pilot Bore Timing Pulley
The 38-14M-55 HTD Timing Pulley ensures zero-slip synchronous tracking within aggressive powertrain environments. Spreading heavy rotational friction across wide 55mm timing belts, its 38 deep curvilinear teeth prevent mechanical timing fatigue. It arrives as an unbored blank with a stock centering guide hole, ideal for custom-boring unique millimetric shaft clearances.
