What's in the Box

Info

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 '55-'68 short-style water pump with either a 5/8" or 3/4" shaft.

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.

Get the correct pulleys for your application by learning which water pump you have as explained in our tech article. SBC - Short vs Long Water Pump

Could be better.

March 30, 2016
Pulleys seem to be nicely machined and of good quality. Belts are not even close to the right length. Much too long on my sbc so I'll need to purchase those locally I guess.
No, I would not recommend this product.

Merchant Response:

The belts included in this kit are designed to be tight to prevent slip in high RPM applications. To install the belts, hang the water pump on the block with one bolt. Lay the belts over the pulleys, and lift the other side of the water pump with your hand. The belts will be snug, and you'll be able to easily install the remaining two water pump bolts.

Please note that our last inventory of these kits included the wrong length V-belt. The mistake has now been corrected and we can ensure that these kits now include the correct length belts. We sincerely apologize for any inconvenience this may have caused and will gladly replace your old belts if needed.
