Deavers k37 w/ total chaos shackles, did I do something wrong? HELP PLEASE

I installed a new set of Deavers K37 with total chaos shackles this weekend.

The ride is phenomenal, but if anything my rear ride height is a little lower, definately not higher.

When I looked again in the light the deavers look pretty flat, and the total chaos shackle kicks backwards at a 45 degree angle instead of coming straight down like the factory did originally.

I put the bolts in the shackles and front bushings, then lowered the truck to torque them like all the directions I found said.

This is happening with an empty truck bed.

Did I do something wrong? is it possible that the deavers shipped kind of flat? which would explain the extra length and no lift at all?

My first inclination was to just order taller shackles, but at the angle they are going in at I'm not sure that will help?

I'm going to lift it and re torque it tonight to see of that changes anything miraculously. I'll get some pictures then.

Any thoughts appreciated.

 

Definitely need some pictures to help diagnose.. post pics of springs perched on the axle, and both mounting points...

What was in your rear end before this install to where now you think you are lower?

 

Deavers recommends TC shackles for optimal use. K37s should give you a little lift (3/4" to 1") paired with TC. I was running that combo before switching to deaver expo pack.
Everything installed properly ? post some pictures.
iirc there should be a left and right leaf pack. someone recently had issues installing them because the sticker was in the wrong position.

 

Springs backwards ?

Need pics

 

I'll get pics tonight.

I measured the factory springs and made sure the slightly shorter end was facing the same direction still

 

my TC have a slight angle as well on the deaver pack
facing that way on driver side: \

did you have stock leaf pack before or maybe you had a block there ?

 

I think that you're going to find that everything is fine. The setup you ordered is more of a dessert setup, it's designed to offer increased wheel droop at speed rather than to lift your truck and offer more stuffing of the wheel up into the fender well. That's why desert truck always look like they're sagging in the rear. That also lowers the center of gravity.

 

@TheBeast stock, no blocks.

it's a 2021 that still has paper plates lol.

 

he should still get a small lift. I gained 3/4 to 1 " with the K37s. Mostly due to the shackles.

 

@TheBeast did your shackles point down or backwards?

They just seem to flat to me, here are pictures.

 

same for the shackles.
You still run oem shocks. any plans to upgrade ? wonder if that's a limitation.

 

@TheBeast Yes, I have fox 2.5" tuned from accutune in front. As soon as the rears come in stock they'll be custom tuning those and sending them to me.

 

Can you take a picture of the top of the leafs at each mounting point..?

The leaf spring ending with the larger military wrap should be mounted at the front of the truck towards the cab.

I can’t really tell from the pictures but it looks a little off to me, maybe because they just look so flat like you said

can you also take a pic of the truck from a distance so we can see how much your rear is lifted..?

@TheBeast you have the same leafs ya..? Do you have more gap between your bump stop and the frame..? Looks incredibly narrow for aftermarket leafs

EDIT:
Definitely not apples to Apples, but my Icon RXT leaf pack at option 2 seems to be giving me at least double the mount of lift and I have a couple hundred pounds in the bed.

 

I just went through this. Brand new Deaver springs and got total chaos shackles. My rear end was lower than it was stock. Replaced the shackles with the originals and my rear lifted about 1 1/4" to 1 1/2".

 

In your second picture you have negative arch, that doesn't look right at all.

Do you have any extra weight in your bed?

 

I have the expo pack with 2 more overload leafs (total of 11 leaf) + superbumps so the gap is actually smaller for me. i can't even fit a fist between top of superbump and frame. I also run the same ADS bypasses as you.
K37 should have 9 leaf iirc.

 

We have inverted shackles, for our trucks the longer TC shackle removes lift. 3rd gen has regular shackles.

I would send some pics to Deaver and see what they say. You have the recommended shackles so I don't see why you're getting negative arch at the back and flat up front. Almost looks like the leafs are assembled wrong.

 

That S shape in the spring is caused by axle wrap bud. You need to remove those and have them re-arched and then install the SDHQ traction bars.

Have you been towing or hammering the skinny pedal? Or had some high traction events? With the power our trucks make, the weight, and diff ratio, our trucks tend to wrap the springs under load/takeoff. It’s especially prevalent on the softer springs, like the K37s. I had a set of U748s that resisted this a bit more, but with softer springs, its bound to happen.

Side note: Why is your bushing all chewed up? Looks like someone forced the shit out of a bushing into the hole?

Check out this video from SDHQ. It helps portray the issue.

@the_midwesterner they’ve been on like 3 days, but looked like this when they were assembled. I did tow, but just my duck boat, it only has a couple hundred pounds of tounge weight, I can easily deadlift the front, and I move the trailer around by hand quite often.
The bushings aren’t eaten, that’s just excess grease squeezing out in the picture.

@Voss I thought the deavers wouldn’t fit with stock shackles?

@Darkness completely empty bed. Only extra weight was my b&w drop hitch which I sure hope isn’t enough weight to matter lol

 

If these are made for your truck and got wrapped that easily something is wrong. I really think you should reach out to Deaver. The springs should be able to handle the torque the truck puts down. I have had springs from another brand for almost 10 years and they still have plenty of arch, granted I have 70 less torque but that isn't a substantial difference.

I agree with the bushings too, those look a little mangled but that won't lead to your springs having bad shape. Get in touch with Deaver, maybe you got bad springs. A traction bar might help but thats a band aid for badly built springs.

 

I would reach out to Deaver and see what they will do for you. New springs will not have negative arch in 3 days. And don't let anyone tell you it is. Mine did the same thing. Not a fan of deaver's quality control or their customer service.

 

I'll try to contact Deaver to see what they can will do.

@Darkness the red poking out around the bushings is extra grease that squeezed out during install, the bushings themselves are black and still look perfect.

 

Red grease
Black grease is the fastest, bad move

 

Here's the backed out view of the truck, Kinda hard to tell in this one, but its 1=1.5" higher in front. lifted 3" or less up front.

 

Can definitely see the rear sag .

Reach out to Deaver and keep us posted.
Hope it works out.

 

Nice looking truck! Wheel and tire size are just right.

 

oh, i see the problem. your truck is white! swap that out for a black one, everything should sort itself out then.

edit: in all seriousness, i agree with others that something is not right there. my OEM springs are ten years old and have more arch than yours.

 

Didn’t realize they had been only on for such a short time. if they looked like this when you got them, you shouldn’t of installed them. There is definitely something wrong with them. This similar symptom can occur with axle wrap, but it happens over time and/or from very heavy traction events. Give Deaver a call, like others have mentioned.

 

maybe they sent you the wrong one and it got mislabeled at some point.
Did you buy from Deaver directly ?

 

Call me crazy, but for the longest time the number 1 complaint of the k37 is how soft they are. They have no carrying capacity built into them and it seems many guys have gotten only the lift caused by the shackles?
