    My buddys k5 has a 4in lift with 35" super swampers. Not sure how wide but theyre WIDE. They rub on the frame in the back (barely), he wants to put a 3in BL on it :doah: to get more clearence. Should he get spacers for the rims? Would it be way to sketch to grind the smallest amount off the side of the frame where it rubs? I wanna convince him not to go with the BL, esepecially since he's keeping the tire size (front fenders are trimmed so that doesnt rub). And he thinks he wont have to worry aobut driveline, brakeline, etc with a BL. Driveline I understand but the brakelines are gonna be a problem and whatever else right? I say zero rates but he thinks they're too expensive, and know that I think of it, can you have blocks with zero rates?

    If its rubbing the frame then a bl wont help, because it just lifts the body not the frame. You never want to grind a patch of the frame out. Rear spacer will probly be the best. You just need to check them to make sure there not lose. What size backspacing is he running?

    Haha yeah I never thought of that the BL wouldn't help :doah:. Figured about the frame, but its just barely its tempting. I dont know about the backspacing, but it's not like they're tucked into the fenders, they stick out way more than mine do...but I got 35x12.5

    are the tires under deflated because that could be part of the problem?

    I'm not sure how that could be part of the problem but no they aren't

    I am just not seeing this. Even with an enormous amount of back spacing and 15" wide tires the tires should rub on the spring, or inner fenders before they come anywhere near the frame. I rub on the inner fender sometimes at full stuff, but thats not a real big deal. I included this pic for reference. I have 4" backspacing, and 12' wide tires on 10" wide wheels. I bet there is 8-9 inches between my inner sidewall and the frame plus the leaf spring and the shock is in that space as well.

    Same here I run a 37X12.5 on an 8" rim with 4.25" backspacing. I also run the inner with the inside sidewall of the tire but no where near the spring or Frame. The frame is set back under the body by about 7-8".
