Hey,

I am looking into a big lift probably around 6" but its for my dually and i still need something i can pull a pretty decent load with my gooseneck. Any opinions?

 

Well, first off we need some more info.... year of the truck mianly, engine and trans would be good to know too.

How heavy is trailer you want to keep pulling? You put on a lift to clear tires, and bigger tires are going to suck down your pulling power, meaning you'll be looking at a regear if the trailer is heavy enough. I don't know what you consider a "decent load", but RVs and stock trailers can easily be over 12000-15000#s, and that's what I consider decent. If you're planning on towing in that neighborhood, you might want to reconsider the lift, or go with a smaller one so you can keep relatively smaller tires.

If you're worried about keeping a decent RGAWR, then you should be looking into add-a-leafs for the rear axle, paired up with some airbags (if there are any made for a 6" lift, I don't know). I'd stay away from a "kit" because either they tend to come with just a block, or the springs (ie deavers) are lift springs and not the kind you want to be towing a heavy gooseneck with.

There a a bunch of ways to lift the front, and different brands do different ways better than others, so I'll wait until you say what year truck you have before recommending anything.

If you want to look on your own, Icon, Rough Country, ProComp, and Skyjacker are a few of the big names, but there are others. I'd personally recommend a mix and match approach, because you'll get exactly what you want that way instead of being restricted to one brand's way of doing it.

 

Ok its a 2005 ford f350 6.0l diesel, auto trans, dually.

I pull a triple axle goosneck with probably 10 1500lbs hay bales, a stock trailer, and a 28 5th wheel. I dont know what the stock truck sits at now but i want a more agressive stance maybe not 6 but i want to get a decently agrresive mud tire on it.

 

OK, you have a bunch of great options for that year.

For the front, Icon is hard to beat. Great replacement coils, a great trac bar replacement, radius arm brackets, the works. It's one of the better put together kits that works right off the shelf. An alternative route is factory 7000# springs and either top hat spacers or BDS lower perch spacers, this is a good way to gain about 3 inches, and beef up the front end if you have a heavy ranch hand style grille replacement or a winch. Up front, you can clear 34s bone stock, with a 2" lift you can put basically any 35 that fits your stock wheels. Most 4" kits clear 37s, but your factory 7" wide wheels are going to be a problem if you want to run that size, because a 12.5" wide tire is a beast for a 7" rim. I think Rock Star dually wheels look great, but not everyone is a fan of them, or the black that they come it, but they have a good selection with the right extra deep offset. In the back, wheel spacers will push your outter tire outboard so the tire walls facing each other don't rub together and cause a blow out. I've never towed or hauled with spacers, but some guys here have so hopefully they'll chime in.

From personal experience with the 6.0L, the 3.73 gearing on the SRW trucks was a bad decision, 4.10s or 4.30s should have been stock options IMO. If you have 4.30s, then putting 36" tires should be roughly like towing with a stock SRW truck. Exactly how big you want to go with the tires is going to determine if you'd benefit from deeper gears.

You said you pull a 5th wheel? Before deciding on tire size or lift height you'll want to hook up and measure the clearance between your bed rails and the trailer, and look to see how much of an angle change the trailer can handle. Then decide if you want to change the truck or the trailer to suit your needs. Goosenecks shouldn't be an issue, they're usually more tolerant of bed height changes since they're narrower up towards the pin.

 

Wow lots of info, So i will look into icon for the front, do you happen to have a link? And what do you recomend for the back to keep it fairly level. Then i need to look into spacers for the rear. And then you would also recommend putting in 4.30 with 36's like i want.

 

soon as I saw the words Gooseneck and 5th wheel I was wondering if this would get brought up.

@ OP...I think you are playing with fire trying to lift a truck that tows a 5th wheel. With a 6" lift, you are going to see a gain of 4" of hieght out back (assuming your lift levels the truck), and then 35" tires will give you another 1.5-2" of height. So all said, your truck will sit 5-6" taller after lift & tires.

 

Ok so like texastech suggested, i am looking into a 4" with 35s. That should work just fine with my trailers

 

How about a level kit for the front, then a simple AAL out back? It will let you fit 35's and won't really change your overall height out back.

Between a AAL and the tires, you'd see about 1-2" of more height out back. when you level the truck, the rear-end actually drops a tiny bit (think fulcrum effect). The AAL will give you an extra 1" roughly to offset that.

Plus the AAL will help a bit with those trailers you are yanking around. Best part, you can level and 35" tires for a lot cheaper than a "true lift"

 

ok skyjacker AAL adds one inch, then with the leveling kit what should i do the coil or spacer? And then spacers for the 35s in the back?

 

ICON VEHICLE DYNAMICS Suspension Systems, Shocks and Lift Kits

My ONLY choice for super duty lifts

 

I went to TruckToyzPerformance.com and searched their "Gallery" for any 2005-2007 F350 Duallies with any kind of lift fit. There were only a few listed and almost all of them had the 4.5" Icon lift kit and 35" tires. I didn't see any with a 5" or greater lift kit... probably because it makes the "working" part of the dually a "mute" point.

Here is the link... just enter the appropriate search criteria.

Here are a few examples:

2005 - 4.5" Icon Lift Kit - 35" Tires


2006 - 4.5" Icon Lift Kit - 35" Tires


2006 - 4.5" Icon Lift Kit - 35" Tires


2006 - 4.5" Icon Lift Kit - 35" Tires


Give them a call and they can tell you what is required to make this setup work properly.

 

Thanks Furian, Thats how i want my truck to look.

 

Let us know what you decide to do... Thanks!
