    I have a '99 F-350 7.3 4x4 and I see a lot of them lifted. I like the idea because with larger tires I can actually get a bit taller gear ratio without touching the gears, I don't like it running at 2500rpm at 75mph I rather have it down towards 2100-2200. Any suggestions on Lift and tire sizes without going to spacers or larger rims than the stock Alcoa's ? Maybe a leveling kit and running 35"s?

    Thoughts?

    You could probably fit 255/85r16’s on the factory Alcoa’s without a leveling kit, they are a 33” tall tire. Anything wider could potentially have wear issues on the narrow stock wheels.

    I think you are on the money, I have been doing a lot of reading today with many owners saying the same thing. I have to double check but I think the stock tires are around 30/31' tall so 33's will drop the R's a little amount but more than likely enough to feel a small difference. I saw the same year F350 on the highway with what looked like 34/35's off road tires tall and thin on stockers and a small leveling kit and it looked exactly what I wanted but I had to turn off prior to finding out.

    With a 285/75r16 (33's) and 4.10 gears, 5 speed manual, I'm at ~2200 @ 70 mph.
    '96 F350, SRW, 7.3, 4x4, 5 speed, no lift or leveling blocks.
    I don't think 285's will fit on the duals.

    Mine is an automatic 4 speed so the higher R's. 285's and 255's seem to fit according to a few forums and have a 1" gap but to make sure I will check with a few tire shops. I may have to go with a 1" but a lot of guys on the Ford forums run the 285's and 255's on stockers. We will find out that is for sure. :)

    I had a 2000 Excursion I bought new. Those old leaf sprung front ends are easy to lift. I did crossover steering and a 12” lift to run 40’s. If its gonna ride like shit with leaf springs it might as well be big.

    I've been thinking about doing the same thing with my 2001, 7.3 CC Dually. The 17" Wheels and 30" tires look like golf cart tires on this huge truck, lol. FYI - The 7.3 runs happiest right at 2,400 rpm's.

    There is ONE option for factory 18" wheels for our 1999-2004 trucks, and that is the 2004 King Ranch/Lariat/HD wheels. 3 different polish and finish options for the same basic 5 spoke wheel. All the 2005 and later have almost 2 inches more positive offset and will not fit without spacers. Screenshot_20191002-103625_OfferUp.jpg Screenshot_20191002-103559_OfferUp.jpg

    What about the kelderman air suspension i saw on here for sale. I love mine. Think he wanted $3500. I am going to the 24 inch dually wheels cost is about $3500 then can do 35s without the huge sidewall and they look great also.

    I ran my Y2K f350 srw 7.3 on 35s and the low end, off the light power was not real pleasing when towing my 5er.
    I had only done front leveling by switching front leaf springs to aftermarket. This did improve the ride.
    After the typical bfg/ford tire wear used up those tires I went back to a 34inch Falken AT and have been happy.

    Maybe 33's for mine are a better option, get a little give a little.

    greg, I had this same set up on a 1995 with the 7.3 and it worked really well. 225/85/r16

    They are just a little taller than 33" but skinny enough to work with the DRW.

    Gear Vendors.

    By the time you buy a lift, wheels and tires, a Gear Vendor might be cheaper. And for sure a whole lot more functional. I LOVE mine on my 7.3.

    Best thing ever for towing.

    Those are 225's, they look perfect for what I was looking for. What brand are they? and how do they work in loose dirt? I searched for 225/85/16 and discount and a few others say they do not exist.

    That was going to my next project on one of the two trucks I bought. On 99 I wanted a bit more aggressive tire for some light sand and dirt area work nothing huge or deep but just enough to get me through it without having to go into 4 wheel drive for short distances, also wanted to just put in a leveling kit and with a taller more aggressive tire and I figured the benefit would also be a drop in R's so I could drive 75-80 without feeling like I am pushing the R's.

    I have a 4in lift on my 01 and I’m currently running 35x12.50r20 tires on it and the fuel cleavers with the offset that i don’t need spacers for the back.

    Not too happy with the wheel choice but i wasn’t about to spend a million bucks on something i liked less on a truck that gets driven 2-3,000 miles a year.

    I went from 22.5 alcoas on it with 255/70r22.5 and i am definitely happy that they are no longer on the truck but i liked that style wheel
    Way better.

    At full lock the 22.5’s rubbed the leaf springs and the tires measured out at about 37’s. With the new set up it doesn’t rub any more at all.

    EDIT: if i could of found stock 5 star alcoas i would of rather had that but every used set i found were fucked and no way i was paying 500 a wheel on ebay.

    To achieve what ur going for, your going to want to run a 315. I have 01 7.3 4x4 an it runs those exact rpms that u are looking for on the money. Motor is bone stock, stock intake, with 4" exhaust turbo back 75 at 2100 all day 80 is 2300-2400. Americas/discount tire will not mount a 315 on those stock Alcoa rims anymore ins. Reasons rims too narrow. I had to buy new methods to run them but still kept with the 16in rim, pretty sure they are 8.5" wide. I'm a fan of more rubber than rims on my trucks. ;) lift is 4in pro comp in the front all leafs no block. Ass end stock, I call him Hoss. :cool: 20191002_172149.jpg

    As far as my trucks power i am very happy with the tire size choice, it never leaves my driveway without one of my trailers behind it so i put it to the test every time. I live in western Pennsylvania now and the hills and roads are brutal. I know the 7.3 is a “dinosaur” to some but there is no newer trucks towing comparable and passing me by on the grades i drive on frequently.

    My truck does have all the usual 7.3 upgrades plus a SPE full tilt transmission build. It was worth every penny.

    Transmission upgrade is the best option on those 7.3’s. They stock ones are junk

    IMO, you have 2 of the cleanest, low mile 7.3’s around. They are money in the bank, and I would keep them as close to stock as possible. Throw some 255 AT’s on it and call it a day. I would hold onto both of em to keep the miles down, every mod and every mile will only decrease the value down the road if/when you decide to sell.

    Several years ago, A buddy of mine ran across a low mile one owner 7.3 on CL, and I gave him the same advice. He sent me the link, and I told him to immediately go to the bank and buy the truck if it was as clean as the ad. He did, and now it’s worth double what he paid.

    These trucks have hit their bottom in depreciation, IMO. Lots of buyers for clean 7.3’s, especially if crew cab. Once you start modding the price and pool of buyers will begin to shrink.

    They are only worth what someone is willing to pay. I see a lot of these trucks for sale at 25-30,000 bucks. I’ve never heard of anyone actually paying that?

    I love mine but there’s Not a chance in hell i’d pay that for a stock 7.3 truck

    I will stand by my previous statement.

    A properly modified truck properly documented by someone who is an internet darling on a specific forum or website might receive top dollar for a modified truck. Your average dude with a “tuned and built” truck is not going to get a better price than the stock, unmodified rig of the same lineage. Feel free to show me examples with sold prices and I will change my mind. Been watching diesel prices for 20 years.

    As far as 7.3 trucks go, We can agree to disagree. And keep in mind i don’t live in AZ anymore so the market in my area may be different.

    For sure it would be nice to get that stock 7.3 truck and modify it yourself, but we aren’t talking about a precision modern engine here. It’s not like you’re having to delete egr’s and def and worry about if jim bob did it in his back yard.....90 percent of “modified” 7.3 trucks consist of generic ts tuners, exhaust, wicked wheels and ebpv delete pedestals....if we’re talking new, modern trucks than i agree with you. I would buy one stock and leave it stock.

    With all due respect, The 7.3 is an absolute turd in stock form and i’m not sure i would pay more for a stock one than a already modified one.

    Having said all that...for sale 2001 7.3 bright amber metallic cclb dually lifted, tuned, modified 162,xxx miles and ready to roll....$30,000 :D

    I do not disagree, the 7.3 is an absolute TURD stock. And why they command the premium they do is beyond me. I have several buddies with relatively stock 7.3s from 96-02, and I’ve driven them all. And I’ve driven them for work back when they were new (and stock...).

    I know they are better modified, but the old timer RV’ers with enough money to spend 20k for a 20 year old 7.3 want a stock, unmodified truck.

    Show me purchase prices of undocumented modified 7.3s fetching more than stock, unmodified examples and I’ll rest my case. Extremely well documented internet babies not included- and those are few and far between.

    I’m not debating prices on used trucks, I’m simply saying a stock truck will demand the same money- or more- than a modified one without proper documentation. You will never get your money back on modifications when you sell a modified diesel truck, with a few well documented exceptions.

    I did a calculation of all the different tire / gear ratio combo's when I was choosing my setup for my 02 7.3
    Here is the breakdown in the 99-03 7.3 with the 4r100 trans
    (Hope I didn't typo any of this)

    F250/350 single rear wheel trucks came standard with 3.73 unless ordered with 4.11 or 4.30 in some trim levels

    Dually's came stock with 4.11 or 4.30 gears (sounds to me like you have 4.30's if you're running 2500 RPM @ 75)

    Stock tire size is 31"ish tall
    31's & 4.30 gears = 2450 RPM @ 75mph in OD
    31's & 4.11 gears = 2150 RPM @ 75
    31's & 3.73 gears = 1950 RPM @ 75

    35's & 4.30 gears = 2250 RPM @ 75
    35's & 4.11 gears = 2100 RPM @ 75
    35's & 3.73 gears = 1850 RPM @ 75

    37's & 4.56 gears = 2450 RPM @ 75
    37's & 4.30 gears = 2200 RPM @ 75
    37's & 4.11 gears = 1950 RPM @ 75
    37's & 3.73 gears = 1650 RPM @ 75

    I run 37x14's with 4.56 on my '02 7.3 gears because I want a wide footprint to tow through soft sand.

    I know a lot of people paying 25k plus for 7.3's, I sold my Excursion for 22k to the 2nd person that saw it, it was very clean, set up perfectly, bone stock engine but with a leveling kit and 33's. I have been looking for another EX in the condition mine was and they are around 25-27k now and are selling with a little negotiation. As for dually's I had an offer from a guy that was looking at the black one right before I bought it that said he would drive right down and give me 22k for it after he saw it from the previous seller. In the end they will sell for any amount of money if there is a buyer willing to spend it on what they want.

    Now that is a great looking rig...I want to do everything possible to keep my stock Alcoa's, since I was a kid I really liked these rims on trucks and now that I have them no way do I want to get rid of them, for now at least. Both trucks have the same size tires and rims, black one is a 4x4 with 92k now and the white one is a 2wd with 55k original miles.

    One thing to look out for putting wider tires on the stock rims is the gap between the rear tires. Some people have to put a spacer between the rear wheels, otherwise the tires will touch at the bottom, especially when you have a load on them.

    Eh, thats pretty damn high in RPMs for the 7.3. In my 02 (3.73 gears), I notice the MPG drop off REAL quick over 70mph (~2000rpm).

    I think you two actually agree more than you realize. Bottom line, the 7.3 is a sought after truck/engine for a number of proven reasons. Whether no mods, professionally done mods, age of driver, purpose of use, it all goes into the value. A beat truck is beat, no matter the engine. That said, nearly any 7.3 in good shape w/ reasonable miles will garner a solid bid and one that those unfamiliar question. We can usually spot a truck that is worse for wear. It is one of the few trucks that are chosen over much later models because of their simplicity, proven strength, no def additive and confidence in limited maintenance.

    Disclosure: I have a 2001 F250 7.3 2WD Stock running gear, Pro-Comp lift.

    Great info. I have your 2WD twin.

    Did you use a website that has this calculator or did you create a spreadsheet? Curious.

    1D08ACBF-6AA4-4602-8325-D06156DDFB0A.jpeg I have a 99 it’s got a 4 inch with 35s. I did have to put the 2 inch spacers on the back. But used the stock wheels. I’m sure I can fit 37s on it without cutting anything.

    Update: 70mph and 2000 rpm got me 19.9mpg in my 02 7.3 (empty). I tried to see what 2400 rpm would be speed-wise and at 2300rpm and 85mph I decided not to go any further haha.

    Beyond me also man. There is one 7.3 I know of that I would love to have but it is iconic. My good buddy owns it.


    That's me in the white shirt...

    Installing the leveling lift 2"-3" shooting for 2" on the Black 4x4 today, have to make sure it and does not bring the front end higher than level, also going to do the white 2wd 2" leveling. Next will be Shocks. Suggestions, Bilsteins or Rancho's?

    Well that sucks, the shop I had the trucks at said they could not do the leveling kits because the trucks are too bit for their racks. Oh well I may do them myself and get the alignment done down in town.
