Unde drive water pump pulley

[GMCTRUCKS]

Might any member here have the under drive water pump pulley for my 1993 OBS 5.7 GMC truck the pulley set I bought just came with the crank and alternator pulley?
Thanks! GMC

So your water pump will turn slower? Okay.....

I was gonna say most under drive kits come with a smaller crank & a larger alt pulley I though

No I'm wanting it to go back to stock since my crank pulley is smaller now I do have a high volume water pump and a all aluminum much bigger radiator than stock but I'm just wanting the pump to put out as it did before now it doesn't over heat on these HOT Texas summer days but it will go up and accidents occur over here example on the freeway one can be stuck a long time just crawling oh I would rather go with a pulley than add a electric fan when in that situation??

Yes they do but I bought only those two not the more expensive kit that comes with the pump pulley to compensate for the smaller crank pulley.
