2004 F150 to have an IRS. - Focaljet

**biker16** · 05-23-2002, 12:43 AM

the F 150 will be replaced next year will share the Independent Rear suspention form the expedition.

also will have a 100% hydroformed frame.

the platform will make heavy use of structural foam and boast a 42% increase in tosional stiffness.

cool, now if they can just make some v-8's with a little more grunt. [img]graemlins/thumbup.gif[/img]

the 3v modualar V8 has been delayed it is expected to bow in the F150, not the expedition as was expected.

also the 5.0 modular is on schedule they are making an easy 350hp from 5.0 liters.

We're talking F-150 here, not -250, -350, -650. It would make sense in the lightest duty version.

**OmniFocus** · 05-23-2002, 01:16 PM

I never said any pickup had IRS. I said many companies have been developing them. Mosler engineering for example.

This isn't exactly a subject worth getting passionate over. It isn't like anybody here is truly qualified to determine the exact effect before the truck ever exists.

A pickup may very well have a use for it, and it might not reduce suspension travel or payload capacity.

3 valve mod motor....hmmmm that's interesting. Now the Five-oh modular w/350 hp...is that 2v or 4v?

**MattHarrell** · 05-23-2002, 07:32 PM

It's my understanding that full size trucks tend to not have IRS more because it's not as good for towing, not so much for ground clearance reasons.

**biker16** · 05-23-2002, 08:26 PM

the 2003 F150 may have an IRS a source has stated that the 2003 F150 he saw had leaf springs.

the source I quoted from is also a reliable source of information (Wards Automotive reports 4/29/02 pgs 1 and 4). I guess we will have to wait and see.

they both could be right. theone with leaf springs could have been a current F150 frame with the new body? or the 2004 Superduty.

Why not have both? I dont see any reason why it couldn't work. You could have and IRS as an Option for people who only do light duty towing/loads and for the Lightening, and the Leaf Springs for people who require the Truck to be a "Truck" [img]graemlins/evilgrin.gif[/img] I'm willing to be that the new 2003 Expy/Navagator Frames are very simimlar to what the 2004 F150 will have.

That's a pretty good thought.. They might be gearing up to make the SUVs more "car-like".

**Erica** · 05-23-2002, 11:20 PM

Being an F150 owner, i also belong to F150online.com...so i'll ask around. Haven't heard about any IRS on the trucks coming out yet... are you sure it wasnt on the ranger? That seems more feasible. I could definitley see them adding leaf springs to the newer 4x4's instead of having to install them ourselves. Guess anything is possible.

More grunt in their V8? What's wrong with the 5.4 litre? Are you talking like a 5.7 or 5.8? I still get a good size of power from my v8 4.6.

IRS on an F150? That is the stupidest thing I have ever heard. You cannot get the necessary ride height from an IRS without doing bizzaro stuff (ie Hummer).

This is totally, absolutely, positively not true.

**OmniFocus** · 05-24-2002, 12:19 AM

How do you know they DIDN'T do "bizzaro" stuff? There have been companies developing IRS setups for pickups for many years now.

I wouldn't doubt it, myself.

**poondobber** · 05-24-2002, 12:33 AM

What PICKUP truck, in the same class as F150, has an independant REAR suspension?

None.

Its not impossible. But a pickup would have no use for it and the decreased suspension travel would decrease the payload capacity.

hey just look at the "bizzaro" things they did with the focus suspension [img]images/icons/tongue.gif[/img]

**brian** · 05-26-2002, 12:55 AM

Didn't the towing capacity of the Expedition go up with the new IRS? I think it's up to 8900 pounds or something like that. What's the max on the current F150?

**biker16** · 05-26-2002, 03:07 AM

the max towing for the current F150 is 8800lbs and
max paylaod is 3150lbs.

the expedition is 8900lbs towing and a COG limited payload of 1600lbs.

the design lowers the floor by up to 9 inches. suspention travel of 9 inches.

**poondobber** · 05-28-2002, 09:11 AM

Having an IRS will not affect towing capacity. It will only affect the payload. As you can see the max payload of the expedition is half that of the F150 and its not because the Expedition already has seat and crap in the back.

Also, the Expedition is no longer considered a truck by Ford. It is considered a car. Same as the Explorer. Which is why they put an IRS on it.

I could go on for days arguing this, but the bottom line is: there is no reason for an IRS on an F150. Maybe on a lightening but no other F150.

**wmudavey** · 05-28-2002, 09:31 AM

I would not say it is considered a car. It is still counted as a truck.

**biker16** · 06-04-2002, 02:40 AM

Ward Automaotive reports seems to have backed off the F150 IRS story they have another source that say "don't expect the IRS for 2003" they still claim that thier was an IRS developed for the F150 just that it may not be available in 2003.

Sorry about the confusion it was an interesting idea though.

I suspect cost played a role in the decision.
