64" springs and DIY shackles installed *Flex Pics*

[muddermilitia]

I got my 7" long shackles from kert the other day, painted them and installed them along with my 64" rear springs

I gained 5.5" of wheelbase but lost just over an inch of lift. A pair of zero rates should just about level it off.

29" under the rear tire. Once I get my 52's up front and a little more weight in the rear that number should increase more

Yeah, yeah. The first sign of a problem is when the truth is

Hey I think you may need to upgrade the undercarriage a little bit. Here's a little somethin' that'll help stop that little problem

Let us know how they fit.

You're not even close to maxxed out yet...with those springs you should see 40" or more under a tire.

thats kinda what I thought too.

I need to take some pic's of my junk flex'd out. Had 49" under a rear tire using the forklift at work... I stopped because I thought it was gonna flop before lifting a tire, and that would have been a bit awkward to explain.

I think having the added weight of the blazer body increases your flex. Last september I wheeled the truck after I put the cab on and the flex sucked.
Here it is with the stock springs in the rear. You can see that the driver's side rear tire is off the ground

That's why after the suspension is done and the 1-tons are in I gotta finish up my flatbed and im gonna add a toolbox, spare tire, and storage for spare parts. Id like to keep the stock 31 gallon gas tank too, just so I can fill it up to add more weight to the rear

 

[oll' bessy]

are those stock springs? or lift springs? im concidering the same thing and am trying to figure what lift i need in the springs. looks great by the way, nice flex

Stock 1/2 ton springs off of a newer (IFS) Chevy but using a 4" shackle flip.

Yep, I believe they came off a 98 or 2000 era chevy 1/2 ton 4X4 and I flipped the ORD hangers from side to side(so they angled back) and I moved the hangers farther back

have u compressed the rear enough and see if the diff cover hits the gas tank?

Before I installed the shackles, I had used my jack to raise the rear axle way up, more than I think It would ever go in real world conditions and the cover did not hit the tank.

Although I have to flip around the rear (flexible) brake line where it mounts to the axle. But keep in mind this is all with a 10 bolt. So the 14-bolt will be different.

I still need to install a zero rate in the rear, but I am undecided if I will move the axle back or not. If i do move it then I am gonna have to do something about the tank. Raise it up or put a fuel cell in it. Opinions?

 

[iwaxmyjimmy]

did u take the factory skid plate already off?

 

[gmc4cw]

looking good. if you get zero rates I would leave the axle centered. How much more wheelbase do you really need.

as for it hitting the tank, are you going to be jumping the truck? if not then the axle centersection doesn't move that much. when you are flexing one side goes up and one down. the centersection pretty much stays put.

I would keep the tank where it is, or move it up inthe frame slightly. you need weight behind the axle for going down hills. last thing you want to do is stand it on its nose.

 

[blazd88]

Also depends(not mannys lol ) on what diff cover your going to run on your 14ff. Some hit the tank and some dont.

Looks good though!

 

[muddybuddy]

yea u still got alot left. ur right shackle angle is almost how it is when not flexed haha. jack that sucker up more! looks good
