blackss2006 Posted January 16, 2008 Report Posted January 16, 2008 I am looking for either a crank pulley or underdrive pulleys for my truck! If any has any or knows where I can get them let me know!Thanks Quote
BlackSS04 Posted January 16, 2008 Report Posted January 16, 2008 there are some up in the for sale section. but from what i've heard, they give us problems down the road. i opted to stay away from them completely. there is hardly anyone on the site with them on, and thats for a reason. Quote
packjh Posted January 16, 2008 Report Posted January 16, 2008 but if you insist.... thunderracing.com summitracing.com im sure you can find more if you google it Quote
gixxerrider Posted January 16, 2008 Report Posted January 16, 2008 I have one installed Underdrive. It does not have a full charge at idle. It was PITA to install also. Do you want Underdrive or stock? Quote
KissMySilvSS Posted January 16, 2008 Report Posted January 16, 2008 I notice that most don't have them here, but I have heard rumblings about them here and there. What are the problems that these cause down the road? Teddy Quote
BlackSS04 Posted January 16, 2008 Report Posted January 16, 2008 (edited) I notice that most don't have them here, but I have heard rumblings about them here and there. What are the problems that these cause down the road? Teddy The main problem with the pulley is the balancer, it's too small to be able to take out the harmonic's from the engine. The size/weight of the stock pulley is designed to balance the rotating assembly. And the harmonic vibrations will be different with a different size. Also consider that the 6.0L HO engine is newer and bigger than the engines the underdrive pulleys were originally designed for. Edited January 16, 2008 by BlackSS04 (see edit history) Quote
blackss2006 Posted January 16, 2008 Author Report Posted January 16, 2008 so all in all are they worth the money? Quote
brobradh77 Posted January 16, 2008 Report Posted January 16, 2008 so all in all are they worth the money? i'm assuming by that question you didnt read the replies. So the answer to that is NO or everyone would be running them. Quote
383ss Posted January 16, 2008 Report Posted January 16, 2008 (edited) I never had a single problem with mine and didn't have any charging problems. I had it on my truck for about 175000 miles. they are also, NOT hard to install. if its the first time you've ever done it it may be a little intimidating like anything else, but it is not difficult.

BlackSS04 Posted January 16, 2008 Report Posted January 16, 2008 $275 for a tenth is not a good investment. save your money for something with more bang for your buck !! Quote
evallejo Posted January 17, 2008 Report Posted January 17, 2008 Everybody has a point here. I was gonna go the pulley route as well, but after seeing the prices I said f**k that. Save your 280 bucks for something better. If you must know, this is where I was going to purchase it: http://www.rpmoutlet.com/gmsuvasp.htm Quote
shadowsniper3006 Posted January 17, 2008 Report Posted January 17, 2008 I have them on my truck, simple install...if you have a puller that can do it. And an impact with enough torque. DO NOT REUSE THE STOCK BOLT. get a new stock bolt or ARP crank bolt. I've had the pulley's on my truck for around 40,000 miles with no problems so far, and i shift around 6100-6300 right now. Even with the alt pulley i do not see full charge at idle. As far as worth the money...get a cam. I got one tenth in the quarter. Brad Quote
