Hello All,
I have a few questions regarding underdrive pulleys, both generic and
specific. First, can anyone explain to me how they work? From what I
understand, they don't increase hp, only allow you to use more of what you
have (more hp at the rear wheels). Second, what are the pros and cons of
these. I have heard that some guys have charging problems with pulleys.
Finally, can anyone tell me the price of these (installed) and average hp
gain on a 4.7?
In case it makes a difference, my truck is:
2001 Dakota Club Cab
4.7L
Auto
4X4
31's with LSD
3.55
Thanks,
Mike
