Underdrive pullies

[Donzi26zx]

Does anyone make underdrive pullies for our trucks? I know they work and they are a easy way to make Free HP.

I've seen a few for vipers, don't know about the trucks.

the problem is that these trucks weigh 5000lbs.....were as the 5-10 hp you get off a pulley may (may not) make a difference on a 3000lb car.....you are never going to notice it on the truck....
