2000 Ford F-550 Build

06h3 looks like a pile of goodies! are you doing injector cups as a maintenance item or are they leaking? ive been weighing doing that to mine when i do injectors. this looks like itll be a nice runner when your done!

Thanks! I am not sure if they are leaking lol. I’m doing it for preventative maintenance given the mileage.

I hope so! Trying to tackle it all at once
 
Only comparing the ratios when comparing a zf6 to a 4r100 is silly. Especially when you are going down hill. I've yet to really see a built auto hold up to a built diesel, even the $7k fully built trans seem to not last forever.

Zf6 with 4.10s to 4.30s would be the way to go imo.

my experience with 99-04 F450s:

I much prefer 4.30s over 4.88s. When OD kick in at 45mph with 4.88s, it really leaves you wanting more. the 4.30s is a nice compromise.

The UBs are the exact same, all 8x170. That era had a goofy 8 lug pattern specific to that generation, its just adapters. closing in on 400k is a fuckload of miles for a DT444e that worked its whole life, but it sounds like your dumping $7k into the engine, so it may hold up. Drop another $3k into the trans.

Definitely needs a NP205 :flipoff2:

Were 4.30 gears an option? When I was researching regearing my 04 a year ago, it didn't seem like any gearsets other than 4.88 were available anymore.

Better be some tall tires on that bitch for 4.30's. I'm running 35's and 3.73's just about perfect for towing but another gear would be nice when unloaded.

Ya, but with the F550 and all the weight, I think the deeper gears might be better.
 
Stock F550 tires and 4.88s (with a stick) turns like 2800rpm at 70 mph. Way too high for long highway drives.

I used to drive an F550 service truck with the ZF and 4.88's. It was annoying. Even though it was loaded to the gills with a service bed and crane, I still wanted taller gears.

This was a all to common sight.

I am going with 245/70R19.5 to help RPM a little bit. According to spicers site that will get me to 70 mph at 2500 rpm. Right now I think I am at 66-67 at 2500 rpm. I would go 265 but I dont think it would fit in the garage anymore and the options on knobby drive tires in a 265 are much more limited.

I have conflicting thoughts on the whole deal. Some say the RPM is fine, some say it isnt, some say its annoying. I can agree to it being annoying, idk if its fine or not in terms of hurting the engine. This is why I keep going back and forth on whether doing a non factory trans swap or not. The ZF6 wont gain me anything from a cruising rpm. its OD is .72 and the 4R100 is .71 (equates to about 1 mph at same rpm) I asked gear vendors about their setup and they wouldnt even sell me one because they guaranteed it would fail with the weight I have. They dont even want a light single cab long bed F250 towing in double OD with their setup. It would be nice if someone had a beefier gear vendors type setup.

Regearing the rear end is expensive and difficult to find gears. I would say that the trans/gear ratio is the one downside I have had with the truck but I knew that going in and might look for a long term solution. It is weird they had that rear end in there for only a couple years and went to a smaller axle. Maybe it was too overkill? I have the Dana S135 and they went to a S110 after that.

With that said, progress has been made. I haven't been killing myself on it, just a hour or two each night. I have everything out and its down to injector cups.

The previous owner had 5 stock remans and 3 original 387k mile injectors in there. He told me he was replacing them 1-2 at a time. I get its expensive but doing that job more then once has to suck and he was paying a mechanic to do it! It had to cost more in the long run....

Last weekend, I was working on half doors for my 4x4 and I have so much scrap steel that isnt very useful for bigger projects so I made this....I have a ton of bed stake pockets but didnt have rect. tubing that size so I took some 2x2 and some tubing to make the proper width for a tight fit and I made a mount for a vice. Just need to mount the vice. I will continue little things like this for bringing the garage to camp. It will eventually all be stored in a bed side mounted box when travelling. I think I will make some tall light mounts to light up camp and a 3rd member holder. Earlier this year we were doing a new gear setup at camp because a buddy took out a R&P early in the week at KOH.

Yeah, they asked what kind of truck I have, said it was an F550, asked what unloaded weight was, told them 11k. They said we wont warranty it, we dont recommend you buying one because it will fail.
 
I wouldn't worry about the RPM etc. as any solution to that problem is going to be very expensive.

Biggest tires possible, maybe really scrutinize that aspect of fitting in to your garage and let it eat.

I have driven this class of truck for 15 years in service truck use and RPM related failures are non existent, it might be annoying but you could work on those issues as they arise.

I would get some expert opinion on the correct AR of turbine housing though since you will be a decent bit higher RPM than the standard PU use of that turbo.
 
My 97 f350 with zf5 and 4.10 was 2500 rpm at 70mph with stock tires. No big deal just run it. Or spend money on something like a brownie od splitter.

someone else nailed it
you gonna want open exhaust side of turbo up some.
 
We put 245s on a few 550s. It was only a few mph difference. If you need tires, I'd do it, if not, I wouldn't spend the money just for the mph gain.

As far as gearing, with the hp you'll be at, I think 4.88s will probably get old.

My experience lies within 7.3L 450s, they had the D80 not the S## rear axle. Stock to stock, the 4.30s ran better. Theres plenty of power to get the load moving, the 4.88s shift too quick. It's not an issue of letting it sing, but 2400 rpm pulls the same as 2800.

Especially since his engine will be 400HP+ I dont see the need of 4.88s.
 
4.30 gears weren't an option in the F550. 4.88 in the diesel and 5.38 in the V10 gasser.

Honestly, I kept throwing the gear idea out the window for a few reasons until now. I was concerned that too low of an RPM would hurt EGT's and I needed 4.88s to keep things moving with a ton of weight but maybe that isnt the case for both concerns and my options for new gears are very limited as I looked at new gears only and I have only found 3.73s from Nitro at $1250. I did just look at used 3rd members and I have found 4.10s and 4.44's, it says call for price.

That would probably be the cheapest option and better then doing new gears at $1250 even if I could find 4.10s or 4.30s

A ZF6 doesnt do anything for me from a highway cruising RPM standpoint.

a 6R140 only gets me from 70 to 75 mph at 2500 rpm on 33s and expensive/unattianable since US shift backed out. .67 to .71 isnt that much of a difference.

A brownie box would be cool! I dont know what ones to look for as I dont have much experience with them. I have about 1200 ft of driveshaft so putting it near a carrier bearing would make sense lol

From earlier 6 speed allison has a super tall .61 which would be the ticket but costly.

The used 3rd or brownie box has my attention. I am a dumbass for not looking at used 3rds from the start.
 
I'm trying to remember if an np205 has the right thrust bearings to be run backwards
I looked into it once a long time ago but have since forgotten

low range would be a .5:1 overdrive, probably cruise in direct on your trans, lol

I remember a rig years ago that had a 203 flipped around for the same effect.
 
would taller tires be an option there has been a couple f550s that went that route on pirate if i remember right

I 100% agree with you. 4.88s are no bueno for highway driving without larger tires. I had tried to find a set of 3.70s or 4.10s for the s110 i've got, but it doesn't seem like they're made anymore, despite being listed in the original dana spicer catalogs.

My fix is to move to 22.5s with 255/70r22.5 tires all around.

is a 255/70 roughly a 37? would definitely help

going with 22.5 could get you up to a 40. reasonably. used semi tires are cheap, retreads are cheap. the only reason i bring up used is because they will last forever under your light weight truck.
 
22.5's might be the best solution actually.

Do you actually need the gvw of the s135? There is a s110 on ebay with 4.10's

Agree. Yes, the 225/70s are a bit over 36". Running larger than that runs into major fitment issues on the F450/F550 chassis in the front, and bed height clearance issues in the rear.
