Billet Underdrive Pulley Set for Nissan RB Engines
This pulley set gives your engine bay a sleek, modern look — being larger diameter than the factory pulleys, it will slow down your water pump and alternator.
- Water pump pulley: 140mm or 126mm diameter
- Alternator pulley: 87mm diameter
Note: the 140mm water pump pulley will interfere with an aftermarket ATI harmonic balancer, so we'd recommend the 126mm size in that case.
Both pulleys are CNC machined from billet 6061-T6 aluminium at our Napier, NZ factory and anodised for great looks and wear resistance. Compatible with all RB20, RB25, RB26 and RB30 engines.
Pulleys are also available individually — see our other listings.
Fast shipping. Great quality and fitment.
