Pulley kit comprises of a precision machined stainless steel hub which is permanently attached to the alternator with the standard nut. 3 different sized pulley are supplied which give different drive ratios The smallest pulley gives the standard ratio for standard fan speed the larger pulleys reduce fan speed and allow you to fine tune fan speed for your application-Top pulleys are easily swapped by removing the six M6x12 cap screws.
Only suitable for use with our dry sump size bottom pulley
This kit is just the top pulley hub and 3 pulleys
See pulley kit for the matching crank pulley
We also have a replacement top pulley with stainless steel hub to work with BMD and other serpentine pulleys
Belt sizes
Dry sump bottom pulley with smallest top pulley gives standard fan speed -5 PK 838
