Designed with the Kyosho Jet Stream 600 in mind, the Kyosho BPC4050 pack delivers four 4x5x9mm collars to hold propellers firmly on the shaft. Their tight tolerances help prevent slop under demanding use.
With exact 4x5x9mm dimensions, these collars maintain propeller alignment to reduce vibration and keep thrust delivery steady across a range of speeds. That consistency helps when pushing for higher performance.
Constructed for frequent operation, these collars suit both spirited runs and everyday paddling. Check them during routine maintenance and replace when signs of wear appear to retain drivetrain accuracy.
