Here are some pics of the shackles and hanger I milled out of 6061.

They are for my crew cab that I have some 4" lift 52" springs.
It uses the bigger 1.500" bushing.
I also have some 63" springs for the rear with a 4" shckle flip.
I also got a complete greasable bushing set from O.R.D. (Which I recieved my stuff 2 days after I ordered it, Big Thanks to Stephen at O.R.D.)

you suck for having access to those machines.

But those look sweet.
 
Nice job on the machine work!

Are you sure aluminum is going to work in this application though? Remember that aluminum has no endurance limit. It will get weaker with each cycle of the suspension.

Thats what i was wondering. Maybe if i had gotten better than a C last quarter during failure anaysis i could be helpful.....
 
As far as making more, it depends on the demand and what people are willing to pay.

As far as strength, I used 3/4" 6061-T6.
6061 has a tensile,yield strength of 45,000psi,40,000psi
1018 has a tensile,yield strength of 63,800psi,53,700psi

Originally I figured steel was twice as strong as aluminum, So I doubled the thickness. Then I also made them a 1/4" wider. So there is Roughly 2.3 times more material with the aluminum compared to the steel. Going by the Tensile and yield strength though, it should give me some what of a safety factor.
So in my head everything should work:haha:
I plan on putting it through some pretty good test on a K30 Crew cab with at least 40" tires.

Here are a couple of pics of them being made.

From a factor of safety standpoint I'm sure it will be fine. They look plenty strong. What I was commenting on is the endurance limit.

Steel, in general, has an endurance limit. That means that as long as it is loaded below the endurance limit stress, it will not fatigue and will last forever.

Aluminum does not have an endurance limit. That means that every time it is loaded it gets weaker. After some number of cycles it will fail.

Your suspension goes through some pretty hefty loads MANY, MANY times every time you drive your truck. I am not going to go through the calculations for whether the shackles will last 1000 or 200,000 miles, but they will eventually fail. Just letting you know that it could be an issue.
 
So he needs to make them out of steel instead. If he can, I'd be interested in a set.
 
Got a price for both 6061-T6 and steel versions?
 
The bling vultures need to stop with asking for pricing etc etc...remember ladies, this is the garage not the vendor forum. There is no selling here, or asking for parts, prices or availabilty.

Ok, I'm asking him to send me a PM with his price then. :D
