I want to run atleast 33" tires but 35's would be nice (but i dont want them to rub like the ones i have on now, its annoying as hell), im tired of these low profile pieces, and i will be towing a boat here and there longest trip will be 4 hours (if that makes a diff.) im thinkin a 4" will be just fine, im pretty good with my hands but i just dont want to get into a hole to big.

 

just be aware at 35"s tires u will def. notice a lose in power...

regearing ur truck will become ur next lusted after upgrade...

a 4" lift will perfectly fit 35" tires..

might be better off sticking to 33"s and a simple 2" add-a-leaf kit..

p.s. what powerplant ur truck turning ???

 

If the lift manufacture recommends a pitman arm get it! As far as pitman arm puller. You need a heavy duty one, the pitman on my truck was to big for the one they had at the local auto parts store. I had to do some grinding on the puller to make it fit the pitman arm!
Also so some bolts like the ones on the leaf springs have Loc-Tite on them. Best to heat them with a propane torch, other wise even with an impact its slow going.

 

Eightrac - what wheelbase is your truck? Mine is '01 ext cab 8' box. I am about to pull the trigger on a ProComp 4" and your comment about the nice ride is encouraging. I am afraid that if I level I will wish I had done more but don't want to go too high for pulling reasons.

thx...Craig

 

Are you keeping your current wheels? If yes, then what are the specs? If no, then what will replace them?

yea im startin to think ill just stick with 33" tires, especially if regearing would be an issue.

if you mean what engine i got in it, it is a v10 with 4:20 gears




yea im keepin the wheels on, the tires that they have on now are 305/60r20's

 

I have a crew cab short bed F350. My wife and I both agree that the truck rides better than it did stock. A couple things I have encountered:

1. I have a travel trailer and use a weight distributing hitch. I had to buy a 10 3/4" drop shank to get the hich to work properly with the trailer as the hitch came with only a 2-3/4" drop shank. The truck has no problem pulling, even with the 35"s and 3.73 gears, but you can tell that what you are pulling is definetly "back there". The truck can clip along doing 60-65 towing 7k without "hunting". I have other mods done though that help with the hunting. I have a flowmaster muffler, high flow converter, shorty headers, ebay y-pipe, a diablo tuner with a couple custom tunes, and I have removed the EGR from the system completely. My mileage didn't change much as the engine rpm slowed with larger tires and I went with a lighter wheel later on to compensate.

2. Make damn sure your track bar is tight a few weeks after doign the lift. Mine loosened 4 times causing "wandering". I finally caught up with liberal use of a thread locking compound.

I believe 4" is perfect, any more above that and 35s look too small.

 

Does Ford offer 4.20 gears for the Super Duties? I thought that you had a choice of 4.10 or 4.30 gears. If you have 4.30 gears, then you should be good up to a 35" tires.

 

I agree! A 4-4.5" lift kit and 35" tires is the best overall and practical combination for the Super Duties. If you want to see various lift/tire combinations, a great place to go is to TruckToyzPerformance.com. Click on the "trucktoyz installs" button and enter the year, make, model, lift height, and tire size that you want to see. I used this website to determine what lift height and tire size combination I wanted for my Super Duty.

I would actually lean more towards a 4.88 gear if you regularly tow with a gasser. I tow a boat and my travel trailer, rarely, so $2000 for a gear change is not very "economical" for me. Hell, my truck rarely gets driven anymore since I have to drive so far to work. I actually had a guy complement it the last saturday when he found out it was a '99. It looks near new.

 

Thanks for the info. Do you have a pic you can post???

Crew cab shorty should be same wheelbase as mine. I get the expansion joint boogie really bad with this truck and am hoping the lift will help that. I have had a lot of trucks but never had that kind of ride before, although this is the first one of this wheelbase. I mostly pull a car trailer from time to time so not usually more than 5-7000lbs. I also just ordered the Y and FM70 Flowmaster, a CAI, and tuner from 5star. All of that will come together in the next couple of weeks. I want headers but the manifolds are good, only 70K miles and not much corrosion out here, so hard to justify.

Thanks Furian for the link. Lot's of different combos out there.
