I just put a dana 60 under the front of my toyota pickup. Its a standared width 60 with the springs in the stock chevy location. Im planning on running 40x13.50 Trepador Stickies and TrailReady Beadlocks 17x8.5. My question is what backspacing should run so that I just clear my leafs and also protect my lockout? Thank you for the help guys.
