Billet Underdrive Pulley Set for Nissan RB Engines

6 in stock
Select Waterpump Pulley Size
Select Colour

This pulley set will give your engine bay a sleek, modern look and being larger diameter than the factory pulleys will slow down your waterpump and alternator.

  • The waterpump pulley is 140mm diameter or 126mm diameter
  • The alternator pulley is 87mm diameter

Please note that the waterpump pulley 140mm size will interfere with an aftermarket ATI Harmonic Balancer so it would be advisable to go with the 126mm size.

Both pulleys are CNC machined from billet 6061-T6 aluminium at our factory in Napier, New Zealand and are anodised for great looks and wear resistance.

Compatible with all RB20, RB25, RB26 and RB30 engines.

Pulleys are also available individually, please check our other listings.
