So i ordered a Powerbond pulley for my truck because no one had an ASP in stock. I then found an ASP for a good price so i ordered it. Took pics of all three pulleys and weighed them.

Weight of pulleys advantage ASP.
ASP 7.8 lbs
Stock 10.6 lbs
Powerbond 12.2 lbs

Quality of pullies advantage Powerbond.
Stock is a cast two piece that is pretty good quality. the power bond seriously looks like it should cost twice as much as the ASP. It just looks far better from a quality stand point. Also the Powerbond has very high lips so the belt will not get thrown like some have experienced on an ASP pulley. It also has a notch for a key and some cool timing marks on it like old school pulleys BUT you have to have an aftermarket crank or have your stock crank keyed for this to be of any use. The ASP also has a light weight aluminum center section which makes it lighter but if you remove and install your pulley A LOT of times, the aluminum could wear out over time and not be as tight on the crank as when it was new.

Ease of install avantage ASP.
To install an asp pulley you just put it on and tighten the crank bolt. The Powerbond, like the stock pulley, needs a longer bolt to first get the pulley on the crank or i use the head of an old crank bolt and an air hammer to get it on about a 1/2" or so before threading the crank bolt.

Conclusion, it's a toss up on these pulleys. so whichever one you find for cheaper is the one i would go with.

thanks for sharing. I had no idea that there were true bolt on performance parts available for these trucks. do you know what are the actual gains over stock (at the wheel) for each of the crank pulleys?

They are the exact same, as far as performance parts, as any same year Chevy or GMC truck. Most people get anywhere from 5-10 rwhp out of a pulley.
