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.
