Billet Underdrive Waterpump Pulley for Nissan RB Engines
This pulley will give your engine bay a sleek, modern look and being larger diameter than the factory pulley will slow down your waterpump.
The pulley comes in two sizes -
- 126mm diameter
- 140mm diameter
Please note that the 140mm size will interfere with an aftermarket ATI Harmonic Balancer so it would be advisable to go with the 126mm size.
The 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.
We also have billet alternator pulleys available, please check our other listings.
