whats the best underdrive pulley system for the 4.0? are there any kits that come with the pulley, belt, instructions, everything needed? where can they be found? thanks
where did you get it? and does it come with everything cuz i keep looking and the ones i find say i need to get a specific belt and if it doesnt come with it where do i get that?
thanks. why is this only good for 3-5 hp when other brands claim 10-12? are the other ones just a load of bs or is the 10-12 the power it makes at the flywheel or whatever and the 3-5 what you can expect from all of them at the wheels?
