TnA Rear Axle, Front Adjustable Spring Hanger

[CFMi]

Once I get some cash consider me the first purchaser.

Can you clear this up for me? I'm having a hard time grasping it. With these in the stock position you can put a set of 64's and have the wheels centered in the wheel well? How does that work?

Well, the basic concept is that when these get bolted in place of the stock spring hanger, the rear-most bolt hole (for your leaf spring) is in the factory location. So you could bolt them on and run exactly as factory. Then, there are 5 more holes at 1" apart, moving towards the front of the vehicle, giving you 6" of adjustment. Figuring that you might have the standard 52" leaf springs, and want to swap out to 64" springs, the overall difference in length is 12". That should be approximately 6" in front and 6" in the rear difference. Hence the 6" adjustability built in to these spring hangers. Couple that with either of my adjustable shackle flips and you could theoretically bolt on a 64" spring.

Now with all that being said, there are different springs out there that people use, or want to change their wheelbase, or different center pin offsets, etc... That's where there are multiple bolt hole locations in my design. If, say, you put a set of 64" springs in the rear-most hole and mounted a shackle flip further back on the frame you could extend your wheelbase up to 6". So there are lots of different options and ways you could use these!

Perfect that is what I wanted to hear, how much longer is the bracket from a factory one then? Will it hit my tank?

When I get the new design done for the 6-bolt style, I can post up some dimensions on it. It won't stick out from the frame any further than the stock one does, but it will stick further forward on the vehicle, towards a gas tank if you have one there. Maybe you could post up a pic of your stock setup with a tape measure or something in there showing where the tank is in relation to the factory spring mount??

I can do that no problem.

Sorry for the long wait, here is my setup.

Curious to see what you think, hopefully it's good news.

looks familiar lol

 

[Babaganoosh]

Did you make those or have them done?

Did you make those or have them done?

I made them, they bolt tightly to the factory rivet holes, I even used a metric size bolt, almost had to thread them into the frame. I snatched the springs out of a later 90's burb, I thought they were 64's but after measuring they measure out to 60" for all the jigging I had to do to make them perfect, I wish some were available like these or the ones diy4x makes when I did this. moving factory hangers forward wouldn't work for me because it would wipe out a body mount, I see you have a gas tank issue on your set up..... my junk is still in the build stages though, I come on here every now and then for inspiration lol....

Bump for TNA.

 

[CFMi]

Lol, good bump, I missed the update on this one!

It looks like the design I have that will work on the Blazer/Jimmy will interfere with your gas tanks quite a bit. I could possibly make a set that doesn't have as many holes forward, but then 64's wouldn't work out while still keeping your axle centerline in a near-factory location. Want to shorten your gas tanks? Lol. Just kidding. Although adding a fuel cell might not be a bad idea, and removing the side-saddle tanks. I really need to buy a pickup for the shop so I can design things for all you pickup guys too.

How much off would it be? If it is a inch or two I can use adjustments on the spring plates and perches.

I finally came up with a design for the "6 side bolts" style of rear spring hangers. Here it is!

The CAD model:

Some Dimensions for you:

Installed Pics (stock 52" springs in factory location):

The pics of the prototype here interfered with my body mount, but the released design should clear it. I had to cut my body mounts out anyways due to a previous owner side-step mount welded to them, so I just left them alone on this truck. I plan on welding the trimmed body mount to these in the near future.
