What all kind of IFS upgrades do they have for 89 K3500's, or because they are a 1ton are they needed? I mainly use the rig for off-roading and towing. Nothing too insane just some cattle, and supplies every now and then. It had a 6.5l turbo diesel once upon a time, but that died, and we dropped a 7.4l out of a 90's chevy in. It's got a 3 inch body lift, with some support beams added, and it currently has 285/75/16 tires.
Thanks
