Well my truck will not run 60 no matter what rpm it's revs out at 53ish the rear end will not let it go any faster then 53 unless I'm going down hill with clutch in loaded that why im.wondrring if I swapped the tires to 9-20s if that would put my top end at 60 with my rear end. 53mph at 3200rpm is all my rear end will allow me to do unless gravity is on my side
