Billet Underdrive Pulley Set for Nissan RB Engines

This pulley set will give your engine bay a sleek, modern look and being larger diameter then the factory pulleys will slow down your water pump and alternator 

• The water pump pulley is 140mm daimeter or 126mm diameter 
• The alternator pulley is 87mm diameter 

Please note that the water pump 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 the Franklin Performance Factory in Napier, New Zealand and are anodised for great looks and wear resistance 

Compatible with all RB20, RB25, RB26 and RB30 engines
