3/4 ton to 1 ton conversion

I want to know what I'm looking at to convert my truck too a ton. I plan on putting a flat bed on. Can I not change calibars and rotors to a ton because I have the large bearings on my axles. Thanks for any help.

Re: 3/4 ton to 1 ton conversion

No matter what you do brake/axle/spring wise the frame will still be a 3/4 ton.

Re: 3/4 ton to 1 ton conversion

i have yet to see the real differnece between a juan ton and the 3/4 minus the rear springs and hangers. if you have the dual calipers, you share the same front and rear brakes as the one ton. the front 2wd springs are the same. the rear springs on most 1 tons DO NOT have helpers. some did, and it seems like they were mostly duallies though. my 3/4 has a 8 and 7 spring, spring pack out rear and "F350" hangers. well at least thats what they are stamped with. no overloads, and that 2500lb load of pellets never dropped her more than 3/4 of an inch. the frames measure the same thickness between my 85 4x4 f350 gasser dually and 88 f250 2wd diesel, and i see no extra crossmembers. i am not really sure what the extra weight difference is between them, but it seems the SRW F350 was always a bit heavier. if i was going to own a f350, it would be a dually, i would not was my time on a F350 SRW..

no matter what you decide to do, your truck is still only a 3/4 ton. be happy though. most 3/4 ton SRW will carry more weight than most 1T SRW trucks can.. its all about "GVW-Curb Weight= How much junk you can carry". but as for towing, most duallies will take you down there as there GCVWR is ALOT higher...

Re: 3/4 ton to 1 ton conversion

huskyhauler, so your saying it is more of a "load rating" thing than an actual physical difference?
I know my old mans 05 F250 Crew Cab 4x4 Short Box FX4 has a higher GVW than my 89 F350 Crew Cab 4x4 Long Bed. Go figure [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: 3/4 ton to 1 ton conversion

Well I was just wanting to put dual wheels on because it would look better under the flat bed.

Re: 3/4 ton to 1 ton conversion

Paint I don't understand exactly what you are asking are you looking to make your truck a legal one ton by name, weight, paper work or just in apperance the frames are the same the rear is the same the rear leaf packs are the same the brakes are the same the front axle and springs are not but easy enough to change now this is only true if you are staying single wheel not changing over to a dually. As far as saying your 3/4 ton will always be just a 3/4 ton is not totally true. It really depends on what exactly you are trying to accomplish. To say changing the cab is needed is crazy it has absolutly no bearing on anything other than VIN designaton of what is displayed on the title. As far as GVW's are concerned EXAMPLE- 88 F350 standard cab 4x4 diesel GVW= 9000lb. 88 F250 standard cab 4x4 diesel GVW=8600lb. Only difference F350 rear spring pack equipted with a single over load. Truck to truck empty weight diff is the F250 is 143lbs. liter. so the F350 can leaglly haul 257lbs. more than the F250.

If you need any further #'s or spring codes dually adapter info or any thing feel free to PM me I can give you as much info as I have from frame thickness to spring load ratings just let me know.

Good luck
Marc

Re: 3/4 ton to 1 ton conversion

The frames are the same in thickness, etc.. but they are different in width. The one ton frame is 2 and 2/4 inches narrower. A 1 ton rear end will NOT bolt under a 3/4 to unless you move the spring pad, not will the sway bar from a 1 ton fit in the correct location unless you move the mounting location of the links to the inside of the frame (boxing in the frame)..

Re: 3/4 ton to 1 ton conversion

Supercab79, question on rear leaf interchangability. I have an 89 F350 Crew Cab 4x4 SRW and am looking to raise the rear approx. 2-3 inches and soften the ride at the same time. This truck spends 85% of it's time running empty. I was thinking of going to a softer rear spring and maybe an Air helper for the times when I need to bring the load capacity back up. What do you think on this?

I know on the Ranger pickups the 4x4's ran a real flat spring with a block and the 2WD's had a higher arch spring with no block. Was wondering if the 350's had a similar situation? Meaning - swap in a 2WD spring for lift. Or maybe a 2WD F-150 spring for lift and softness?

I would be willing to add a Track Bar etc. to stabilize the rear when under load. What do you think?
Mike

Re: 3/4 ton to 1 ton conversion

As far as the frame differences between F350 and F250. There are no differences in the frames. I have personally swapped drivetrain parts (front and rear axles, spring, sway-bars) between a F350 and a F250. The frame is not different. In fact, the F350 frame had the holes drilled for the TTB brakets for the F250 Dana 44. The TTB Dana 44 simpley bolted into place on the F350. The trucks are 7 model years different as well. I'm not trying to argue with anyone, but, my personal experience with F350's and F250's..........NO DIFFERENCE IN FRAMES. The other differences are drivetrain related only, and they are minor.

Re: 3/4 ton to 1 ton conversion

Has anybody actually ever been stopped for too much weight if it wasn't painfully obvious? Just curious.

If your just wanting to run duals you will need the adapters for the rear. If you don't the tires will hit the springs. Or you could find a rear out of a dually with the pickup bed. It will be wide enough to clear those springs. If you want to run the dual style up front, you will need the front adapters also.
