Was wondering if anyone knew just how much wider the 450 wide track axle is then the 350 DRW. I was considering changing out my oem flares with a more stream line bushwacker or warn 4x and loosing the bumper piece, but wasn't sure if they'd give enough coverage. It seems awfully wide. Also doing it so I don't have to cut my stainless steel running boards to make them fit.

 

Front track width is listed as 68.3" for F350s and 74.8" for the F450s.

So based on that I'd say you are about 6.5" wider than an F350's axle.

 

Thanks that's exactly what I was looking for. Although a little embarrassed that I didn't figure out what track width was on my own...
