Daniel, I believe the ASP's have the largest underdrive. Your best bet is probably Summit. Gains are minimal compared to stuff like cams and headers, but they're gains nonetheless. :thumb:
I believe HitManX sells the ASP pullies for a great price if you're not in a huge hurry for one.
i hear that UD pullies don't work that well with the 6.0. and alot of the people on the silveradoss forums has had problems with em and i was advised to stay away from them. they are better on the 5.3's and 4.8's. and plus, you get very minimal gains for the money your spending.
There is NO difference between the 4.8, 5.3 and 6.0 accessorie wise to make the 6.0s not work. Im running a 420 with an ASP pulley and no problems, its a 6.0 block just like the SSS trucks. Point blank UD pulleys barely give you any HP its one of those things if you have the money and can get a could deal on them and have all the other bolt ons covered then do it.
