Explorer springs, and 235/75/15 tires.
yeah explorer springs, front and rear... make sure all your sway bar bushings are good... drive smarter, I've never felt unstable in my B2, even with stock suspension, body lift, and 30's...
Until I switched to EB front coils, I NEVER kept my front sway bars connected... I didn't need it. even right now (for over a year) I don't have a rear sway bar on my truck but I have an add a leaf and it's stiff...
