The Kyosho BPC3240 Propeller Collar is a core retention part for Jet Stream RC boats. Designed for the Jet Stream 600 series, this pack of four collars helps lock the propeller to the shaft to reduce slippage during high speed runs.
These collars fit 3.2mm shafts and measure 4x8mm, giving a close tolerance that keeps blades aligned and maximises thrust. The secure seating supports steady propulsion whether you are racing or doing casual runs.
Fitting the Kyosho BPC3240 collars is simple: clean the prop shaft, slide the collar into place and tighten firmly to prevent movement. Inspect them periodically and replace any collar that shows deformation or wear to maintain reliable operation.
