Stomis' Return of the Truck Build

Overview Gallery Discussion

Stomis you have given me good advise in the past. When I do my 52 swap what shackle length should I look for or will the stock ones work out ok?

A stocker or 4" will be too short. Notice the bend in the frame in the picture of my pinion angle. Anything shorter and youd be bottoming out. I'll probably wind up switching them out to 7.5" shackles. Those are commonly recommended for 52in spring swap due to how the shackle angle lays so perfect.

Also I recommend you get some nice thick ones from kurt. My friend in town tweaked a stock shackle and broke a bolt with crossover steering. Now his truck has a panhard bar in it, yeah on leaf springs... talk about doing stuff the hard way.
 
Holy crap the bitch moved under her own power.

Today I filled everything up, moved the axle back to stock location instead of 1.5in forward (so I stop smacking my f'ing shackles aka departure angle...), got my rear shaft installed, added an overload and a cut front 4in lift spring to my pack and took her for a drive.

Now the front is way lower than the back.... As if I could find a happy medium right... I was trying to give it some more spring rate due to the ass sagging with a full tank of gas. Now I'm afraid its got too much.

Couple questions.

Does an overload add spring rate? I thought no.

I added a leaf from my old front 4in pack. I figured it would make it stiffer but even after filling the tank the thing is way up there... Would trimming the leaf a few inches shorter on each side lower the amount of spring rate added?

IIRC, over loads (or add-a-leafs for that matter) do add spring rate. It's the zero rates that do not, because they are bolted directly to the spring pack.

Glad to hear you got it going, that's awesome! :wink1:
 
Yes, trimming your shortest leaf will reduce the spring rate. I can't say how much, but it will reduce the spring rate.
 
I'm gonna decapitate someone. My brand new mother ****ing transmission is leaking like a div from what appears to be the front seal....

**** **** **** **** **** **** **** **** ****
I"MG ****ING DONE.
 
An overload spring does not add spring rate, they are just like a really long zero rate that will prevent the springs from over flexing.

Huh????? Not sure what you are talking about, about apparently our idea of a overload spring is quite different.
 
That’s quite possible..

I've never known an overload as anything but the thick spring at the bottom of the spring pack. Minimal curve and no flex. Prevents the leafs from over compressing while loaded or in our case flexing. If you chopped the ends off it would serve the same purpose as a zero rate.

Your thoughts?
 
To me the overload is the flat spring at the bottom of these packs?:

Trimming those will not decrease spring rate at ride height. I was referring to trimming the shortest leaf (above the overload).

Stomis, did you get the converter fully seated? If the converter isn't all the way on the trans input, you could have a leak there.
 
Exactly!! But they are not completelyflat. :D

I did not say the overload would have any affect on ride height. Stormis asked if it the overload added spring rate, I said no.
 
I think we are on the same page. He went on to talk about a trimming a leaf from his old 4" front packs (which would not be an overload).
 
Its a stick so no converter...

I called the guy that did my trans and he told me to try giving the front plate with the 4 slotted screws a quarter turn and see if it stops dripping.

Also my front output yoke on the tcase is dripping like a mofo. I put in 5 quarts as advised on here and I'm being told by two trans guys that it should be 3. Could this cause the leak?
 
Well I'm no help then. I can't see it leaking anywhere other than the breather because it is overfilled.

I'm milling over the thought that the tcase is way over filled. All data calls for 2.5 quarts and I've had two trans guys tell me 3 quarts tops...
 
Well after further inspection the trans would appear to be leaking from the round cover with the 4 screws in it in the front.

The transfer case is leaking from the front driveshaft output, BAD.

I fixed my wheelbase issue with the 1/2in offset on the spring hanger today and plan to install my zero rates and shocks in the front tomorrow. Then its being brought to the guy and I'm telling him its his work therefor his issue.
 
So as you can see the shocks are in. With my shackles at full droop straight down I've got 4-5in of shock travel left :eek1:. I think I need to switch to 7.5in shackles.

I put my zero rates back up front to level the truck and also moved my rear axle from 1.5in forward back to stock as I said yesterday. The 4in lift brakelines are plenty for the droop I have now with the 6in shackles.

O and might I add that 52s with the second longest leaf from a 4in lift pack in the bottom is the perfect mix of flex and street handling.
 
List:

52in front springs - DONE
14in travel vertical mounted shocks - DONE
hardline the front axle and move flex lines to center - Cancelled
weld in adjustable spring mounts up front - DONE
mild boatside
clean up all the wiring in the truck so its nice - DONE
piece together a custom dash - DONE
put another coat of herculiner in the cab
plank the deck (lol) - DONE
stinger for front bumper
finish front bumper so it wraps the fenders
cage the bed with poop pipe
reinstall my toolboxes - DONE
clock my transfer case - DONE
switch out my transmission for the rebuilt one I have thats been sitting in my friends yard for a year - DONE
build a hi clearance tranny cross member - DONE
higher clearance headers into a single stack behind the cab (not to be cool for water tightness)
ARB snorkel
And lots more I know I'm forgetting.
