What's in the Box

Kit includes a cast aluminum double groove water pump pulley and double groove crank pulley, and a matched pair of heavy duty belts. Has a 1:1 water pump/crankshaft speed ratio.

Fits Small Block Chevy V8 with '69-'86 long-style water pump.

Note: The lower crank pulleys in our combo kits are manufactured thicker than normal stock pulleys.  This requires longer 3/8" bolts to be purchased separately.  Allen head type bolts recommended.

Pulley combo review

September 09, 2012
Awesome product that is as stated in the magazine. Direct fit. Even dropped my coolant temp by 20 degrees. Only con i have with the purchase is i had to run back to town to get longer crank bolts because the stock ones will not fit.
Pros:
  • Increases Power
  • Easy To Install
  • Improves Engine Efficiency
  • Lightweight
Yes, I recommend this product.

February 24, 2013
Only issue i have is the lower pulley is alot thicker than a stock one. and now i have to find a longer grade 8 fine thread bolt to mount it securely to the crankshaft. Its not an issue just would be nice to have known or had the longer bolt come with the set.
Yes, I recommend this product.
