    Any difference between 08 F350 and 08 F450 frames??

    Bigred I thought you were looking at a cab & chassis? In that case the 450 and 550 frames ARE identical. The 450 pickup frame is a hybrid. Also, if you're going for the short wheelbase 550 cab & chassis (141"), know that there is no difference whatsoever to the 450 except for rear diff...

    I talked to one of my wrecker outfitters today - he said that with the short wheelbase (141", which is what we need), the F550 is overkill. You get into a leverage issue where if the wheel lift is overloaded it's going to pick the front wheels off the ground regardless if it's a 450 or a 550. A...

    F550 vs. F450?

    Hi, new here to the forums. We're thinking of buying a couple '08 Super Duty chassis' to turn into wreckers. We need at least an F450 (16,000 GVWR) chassis. I understand the F550 chassis is rated for 17,950 GVWR for not that much more money. What is different mechanically? Is it just...
