hey guys im wanting to get some power ont of my truck and i was looking at pulleys so my question is would these be good and how much do you think i would get out of them?

4.0 5 piece combo kit red or blue [4.0combo] - $419.00 : Underdog-Performance, The Art of Power


also if you have any other suggestions that would be awesome!

Thanks

I believe from what everyone on here says, they are the best bang for your buck and you get the most horsepower out of a set of underdrive pulleys than any other single mod you can do. Keep us posted if you get them. I want to do the same to mine. I think a programmer, intake, pulleys, and exhuast would give you a very noticable difference. But your also talking about $1000 or more.

 

i think its something like 11 hp gain (feel free to correct me) its only the underdrive pulley that creates power, the alt. pulley is to fix the charging rate, and the other ones are to look pretty :) haha

 

IMO underdrives are an excellent bang for the buck.
(I'm the one who measured 10-ish HP & TQ increase using a scanguage)
