I hope I am responding correctly, this is the first forum I have ever attended. Thank you guys for the replies. Ok to answer first questions first. In California any truck with a GVW over 10K must go throught the scales, this includeds 350 DRW. This has never been invorced in the past but is now. The 450 was built specifically to avoid the scales, the is not right, the rules are clear if read, all trucks with factory installed pick up beds are not required to go through the scales, unless, it has over a 10k GVW. The trailer I haul was a 25ft, 23K, goosneck with dual tire, dual axle, tilt bed. I haul equipment for my own company, not for hire. The real kicker is that with my new trailer that has a GVW of 9,880, goosneck, single wheel, dual axle, I can haul my equipment with a 3/4 ton and avoid the scales and lic's, but if I use my 450 (eventhough the trailer and load dos'nt change) I must go through all of the crap. With regard to the the rear end just having long studs; that's not the way the C102 medium duty truck rear ends are built. I have pictures I can send whoever is interested. The axles actually runs all the way from the end of the outside hub to the center. I will be checking with Stockton Wheel to see if they can build be a set of wheels that will give me the proper offsets and widths to look correct under a non-dually bed design. Up front, the rotors that mount to spindles have a smaller 10 lug pattern, to that an extention is bolted that is four inchs long and increases the bolt pattern to a 10 bolt large pattern. I hope I have answers the questions. I look forward to you thoughts. By the way, if I could find a SRW 350 or 250 crew cab, as nice as my truck, I woud trade.

Your stock tires have 3,970 pounds weight capacity each when mounted on a single wheel (not duals). So your rear GAWR would be limited to 7,940 pounds with one dual removed on each side and the rear tires pumped up to max (110 PSI?). That would result in a max GVWR of about 14,000 pounds, which is not much less than you have on a stock F-450 pickup.
Don't mess with the rear axle or the hubs, but you may want to replace the lug bolts in the rear hubs with the shorter lug bolts for SRW wheels.
But to do it right, so your pickup looks like an SRW pickup and not a dually with some tires removed, you need 4 new wheels with a 10-on-225mm hole pattern. Your stock wheels are 19.5"x6", but the new wheels could be 20"x8". Then you could mount the same tires the SRWs run, or LT265/75R20. With those tires, your 4.30 rear axle ratio would be an effective 4.02. Your speedo, odometer, and tripmeter would have a 6.5 percent error until you had the speedo calibrated for the taller SRW tires.
No need to change the rear axle or hubs. However, with 10-on-225mm hole pattern, you would probably have a real problem trying to find SRW wheels to fit. And the F-450 brake components are at least 1" more diameter than SRW brakes, so any SRW hub probably wouldn't work on an F-450.
If you want new wheels, then the answer is probably a custom wheel maker that can make you anything you can dream up. One source is: Stockton Wheel Service - Custom Wheels
One option might be to have Stockton widen your stock wheels from 6" to 8". Then instead of your 225/70R19.5 tires, you could run "super single" LT265/70R19.5. That would give you a rear axle ratio equivalent to 3.90, and get you back to your stock GVWR of 14,500. The Drive-axle tires available in that size include Michelin XDE2+, and the all-position tires available in that size include Michelin XZE2+:
Michelin Americas Truck Tires
But warning: those super single Michelins are not cheap.  |
