Project: Rusty Red just needed a new bed.

What's gunna be happening to the front suspension?

 

[4.0l sahara]

Just softer springs. Like excursion springs to lower it some.

 

[Stroked777]

No type of support? Don't some people run a traction bar type deal up front? Is it illegal in your rules for the pull

I've seen it on a few gassers but never on a ford leaf spring superduty. I think the key will be the right shock setup.

 

[Breaking Habits]

Brents truck hopped bad with front traction bars.

Shock and tire pressure is key!

 

[ford rules]

I have a set of excursion springs with about 70,000 miles on them if interested.

 

[4.0l sahara]

Well the body is finally back.

So hopefully this will get going again very soon.

Anybody know how much excursion springs drop them?

 

[4.0l sahara]

I haven't figured that out yet. But i think there are a few different spring codes for excursions. Depending on what motor they have. So a 5.4 would likely have a softer spring than a 7.3

Some of it depend on the springs. I went the other way ( put a 4" truck lift on my EX and it lifted it about 6"), but doing some measuring on our trucks, the best I could figure was the 4wd EX sat about 1 3/4" lower than the same SD.

Gasser springs are definitely softer. You do get more weight transfer, but you need to watch your setup so you don't hop too bad. I've seen some swapping don't under the front of an OBS with different gasser springs, it made a big difference for their set up.

Gasser springs up front helps weight transfer? I guess that would make sense.

I don't agree. Unless your not hanging weight. With 1800# on the front of our pull truck the factory springs are a 1/2" away from the bump stops. If it had softer springs it would sit on the stops hard. And that would loose "lift" when the sled pulls down.

Who hangs weight in drag racing?

 

[Morgan@Midwest Diesel & Auto]

You do realize this is a pulling truck thread?

I know... So you're saying being as close to the bump stops as possible helps weight transfer because you get more lift in the front?

It was for a drag/pulling dual purpose 'fun' truck. He liked it, but we all know how many different opinions on truck setups there are out there. It wasn't my truck, but the combo he finally ran with definitely helped at the drag strip and seemed to work just as well pulling. The front was softer, but not so much that it floated launching.

 

[TRUBBS]

thats a pretty sweet setup. diggin the build.

shoulda painted the engine gotta have it green also

 

[4.0l sahara]

Well I think at least the new x codes will get swapped back out for some v codes. I'm sure the front end will be a little bit of trial and error. As none of us have done much pulling till now.

The springs need to be as flat as possible or concave to the pulling surface to eliminate hop, front traction bars make it hop bad

Have it sag as much as you can like Morgan stated and
Jared had it right, tire pressure and shocks

Well long story short the built long block we bought wasn't in such great shape. So we are building a new motor with a different block and heads. The only thing that we are undecided on is how we want to seal the heads. We are thinking of cutting out a set of stock gaskets and running a fire ring with a receiver grove in the block and the heads. Since this is not a street driven truck I can't think of any down sides. This doesn't seem super common in the 6.0 world but was wondering if anyone had a opinion on this?
