It appears one of the few differences between F250 & F350, is the 350 has a 4" block under rear springs raising height. Am I correct the 250's sit level front to back? Do 350 have same front height and raised rear?
My boat has pretty good tongue weight. If 250 is level, could that actually drop rear below front?

If I buy a 250 & put a 2" block in rear will that affect other items?

I believe 350 looks better, but that rear tailgate is really up there, for day to day use.

 

If you are questioning it, I would choose the f350 knowing what I know now.
I drop 2 1/2 inches with a 6,500 lbs equipment trailer; we'll guess about 650 lbs of tongue weight and several hundred more lbs of stuff in the bed with full tank of fuel.

It doesn't look bad but it isn't level with that weight.

 

Yes, the F350 rear is raised.

The functional difference between the F250 and the F350 (aside from the height) is about 1000 lbs more load capacity in the F350 SRW than in the F250.

There's a concurent thread on the F250/F350 suspension difference, maybe a page or two down in the forum.

Very likely. It did on my '05 F250, which is the secondary reason I went back to the F350 this time. The primary reason for me was the increased load capacity of the F350.

Why not just go for the F350 SRW? I don't think there's much difference in price, and then you don't have to worry about what else might be affected.

Yeah, it's high. In fact, it's about an inch higher than my '89 F350 (and considerably higher than my '05 F250 was), but you get used to it. With an evenly distributed 2500 lb load, tailgate level will drop about four inches on the '11 F350 SRW with 11,500 GVWR.

Kper & FourOne, thnks you guys really helped me make up my mind.

My Ex handles weight fine, rear does drop a few inches, but front has always been lower. First because old springs drooped, then had new springs installed front & rear to beef up. And sits a few inches higher in rear normal.

 

I was debating the same thing. The F350 sits 1" higher in the back due to a larger block. For me it came down to registration costs. Check into what the difference is to register since it varies state to state.

In Ca it was a few hundred dolloars more a year. The F250 was $920.75 to register I wasn't willing to pay several hundred more for the F350. It is just something else to consider (needs vs wants).

 

I went with the 350 srw to get that higher gvwr for having a slide in camper.

 

so it costs nearly 1k to register a pickup truck in california????

the f250 IMO does sit too low in the back, I think this is in response to all the guys who for some odd reason feel the need to put a leveling kit on their trucks, then when they put a load on the thing, it makes it look like a mexican lowrider.

the height is what necessary to a heavy duty truck, because it needs to have a couple inches of travel so it stays off the overloads, If I could do it over again I really should have bought an f350 instead. the 250 handles the weight really well it just sages the back. for me just adding a 2" block to the rear may work the best.

 

I have to type this to meet my 10 characters

 

Adding the block is not too hard. But will that affect driveline or anything else?

 

forget the block,
what you want is another main leaf or two,along with an aux spring.that will set ya right up nice.
just because ford didn't put enough springs under her,doesn't mean you cant.

the problem with the long super duty leafs,is you have trucks sagging far to much when a load is put on.
it's dangerous as it makes the front end light,and steering float.
its much safer to have too many springs in the rear,and not use them all,than it is to have to less and end up with a truck with its tail dragging.

the springs are very long like they are, to improve ride comfort.
unfortunately,this means the trucks sag horribly when loaded.

if you don't want to compromise ride quality,have a spring shop make you an aux spring set of 3 or 4,and have them just under the aux perches,that when empty they don't contact on bumps.this way,when you load up,they will start to work sooner holding your load up to reduce sag,yet ride the exact same as factory when empty.

lower sitting trucks are much easier to load up materials by hand,and will yield slightly better fuel economy.
you don't need spacer blocks to set them higher,you just need springs to hold her from going down from there.

 

Not every pickup truck.

In Kalifornia, virtually all pickups are registered as commercial, regardless of whether they're actually used that way or not. If you don't register it as commercial, there are significant restrictions on what you can carry in the bed (for example, if it's not registered commercial, you techically can't carry anything which sits higher than the bed sides).

The Kalifornia Kommercial registration fee consists of:

1. Base vehicle registration fee (roughly $50/60)
2. License fee (a personal property tax based on the age and value of the vehicle--ranges from a low of $1 for a really old beater to over $1K for an expensive new vehicle).
3. Weight fee based on the unladen weight of the vehicle (ranging from less than $100 for a compact pickup, to over $1000 for heavy trucks). This fee never changes, except upwards whenever the state feels like raising it.
4. Possible extra fees based on which Kalifornia Kounty the vehicle is registered in, plus fees for vanity or environmental plates, etc., if used.

Sound komplikated? It's Kalifornia.

The difference between F250 and F350 registration is probably all in the weight fees, where the F250 is probably in Kalifornia weight klass F, and the F350 might push it over into weight klass G.

Probably more than anyone wants to know about vehicle registration in the People's Republik of Kalifornia, but there it is.


Joe, who only knows the drill because he gets forced to work in Kalifornia sometimes.

 

I would really like to just add the 350 blocks to give my 250 a better stance without a load in it.. Anyone know the part numbers for the 350 blocks and bolts?

 

7C3Z-4730-A

 

Same for both sides? How about the ubolts?

 

That 4730 is the bumper.. the spacer looks to be f81z-5598-ea
and the bolts bc3z-5705-g.. you could check with your
local dealer..
