Clutch - Low Temp Fan Clutch Stud Hub 6.5 97-99 CK For 20 In 9-Blade Fans

Replacement fan clutch low temp (low engagement temp) for all 6.5L Turbo CK vehicle models and is compatible with both the 4-bolt steel 9-blade fan found on 1997 on up trucks as well as the poly Dmax fan  (preferably our 20" shaved poly Dmax Fan).

This is primarily applicable to 1992-1999 6.5L Turbo Diesel CK models, and will work with all stud-mount water pump configurations using a 4-bolt stud on the water pump hub. This will work on standard and "HO" volume 4-bolt stud water pumps and with single and dual thermostat configurations.

Note: This will NOT work on 1999.5 and up 6.5 Turbo Applications with the Screw Mount hub, or trucks adapted to use the silly screw-mount hub configuration (offers no gain).

For the the 1997 on up factory 6.5L trucks, they come equipped with a steel 9-blade fan that is the best match for this clutch, no need to replace for the poly fan.
