PR Racing SB401R aluminium CVD input shaft coupler
Coming from PR Racing and made for the SB401R buggy is an aluminium CVD input shaft coupler. The part is machined from high-quality aluminium, it comes hard anodised to ensure low wear and weighs in at only 1.5g. Using the alloy coupler instead of the standard steel part will reduce rotational masses of the centre drivetrain for quicker spool-up and acceleration.
