3" Full Traction with 35's question
#12
I've got the lift and 35's with heavy duty springs in front and .75 spacers in rear and i get all kinds of rub when i disconnect my sways in the front. Maybe i just wheel harder than you other guys.

HD means heavy duty. You can put these on if you plan on adding a heavy front bumper and winch. Spacers do the same thing but i believe the consensus is that HD spring are better.
