underdrive pulleys for 5.9
i found some jet ones. 25%.are those any good? i mean i understand that i am not making hp, just freeing some up. and maybe some mpg would be nice too.
I have been trying to figure out that question also I know on my buddy's car he noticed a difference he gained some time in the 1/4 mile. If im not mistaking you replace 2pulleys on dodges.
i searched on here and some people like them and some donnt. a couple said they had charging issues. i think that if i could find out which ones are right, all would be good.
I have had ASP's on two different trucks, both dodges. There has never been a charging issue. You get full charge at sy 1200 rpm. Unless you sit idle for extended periods of time with a big *** stereo or tons of lights there will be no problem. I also only do the crank pulley. I did notice a difference on my trucks.
