08-10 F-450 Questions

Hello all,

Our farming operation is looking at a 08 F-450 for a work truck. We currently have a 97 F-350 and we are in need of a replacement and would like to step up to the F-450.

Are the does the 450 have much higher capacities compared to the 350? Besides bigger brakes and different rear end what will we be gaining with the 450? Does it have a tighter turning radius? (read online that the 450s and 550s actually have a tighter turning radius)

The truck we are looking is a 2008 4x4 F450. 113k miles... Anything to look for in the bigger trucks that I don't already know about (I have a 08 250)?

Also, is the DPF-R still available? We will want to do a DPF delete, but not going to tie a ton of money up into it. I have a mini maxx on my 250, but big power is not necessary for this truck. We just want better MPG and reliability. As to the DPF we plan on keeping it on the truck but breaking out the ceramic inside. How hard is this to do?

Thanks!

The F450 is rated to carry and tow more than the 350. The frame and suspension are all heavier than the 250/350 trucks.

Front end is a Dana 60 with a 6000# cap, rear is a Dana 110 with a 14,000 cap. depending on the truck the factory LS unit is a gear type and dead nuts relaiable.
The wide track axle give you a tighter wheel cut 45 vs 35 degrees.

Do some suspension mods and the truck will carry alot. Mine I installed a Kelderman system on, and have increased the carring capacity significantly.

Two things to do delete the EGR and DOC/DPF. the truck will last a long time.

The gross combined is 33k for a F450.
The gross combined is 27k for a F350.

I think the bed is rated around 5k for the F450.

F450's have 4.88s or 4.30 gears. You can get lower gears from randy's. The rear is about $1k...which is cheaper than it used to be.

The F450 does have a tighter turning radius than an F350.

The F450 has 19.5s and the F350 has 17s.

I have an F350 because the 4.88s in my F450 were too much and I ended up getting a really good deal on my F350.

I have an H&S minimax that I bought two years ago...I don't keep up on the current tuner side of things.

As far as hollowing out the DPF is not that bad. It was about a 6 hour affair for me. The CAT material is soft, a hole saw will go right through it. The DPF is alot harder. You can drill the ceramic with a masonry bit (I used a 3/4" bit). Drill a bunch of holes then break it with a jack hammer. If thats all you are doing should go quick. I also cut out the welds on front of cat and back of filter and removed those small pieces of pipes. Then I welded a straight pipe through cat and filter on same spots as factory was. I got pretty damn close to those nice weld seams they had. If you look underneath the truck you gotta get " forensic " to say there has been work done to it.

Cat, you hit the inside media with a large diameter (1") drift and a hammer and it will shatter.

Getting the guts out of the DPF is not a fun affair.

Big piece of pipe and a sledge, after drilling holes.

WEAR A RESPIRATOR WHEN YOU ARE DOING THIS!!!

Alright, so what tuner do I want then? We don't necessarily need any more power. 40-60 additional horsepower wouldn't be bad, but it is not necessary.

At the end of last summer I sold my ORIGINAL (no tranny tuning) XRT after I bought a Mini Maxx.. I should have kept it!

We want a tuner that will be safe and help with MPG. Not really wanting to spend too much... so a mini maxx or spartan are out of the question. Just something safe..

Dpf-r. You can get a 70hp tune or no tune at all. It just allows you to be deleted. They're like $300--$400

Edit: I just read the thread, I was on my phone and didn't read the previous post my bad!
