Long Travel BS Thread

Smack’m back if you already haven’t.

I’m more appreciating you marked your hardline with a paint pen

 

Hahaha I noticed that too.

 

When you strip it and send it on in anyways you can’t be too careful

 

My deavers are also continuously doing this as well. In my opinion it’s from going negative arch. Nothing I’ve done stops it.

 

I'll just have to live with it for the time being. I have longer shackles and a lower bump zone than stock so my springs are not going negative much to my knowledge. I'm about ready to message Harry for pricing on the JD spring under kit any day now. I just keep waiting because I want to finish my front before I start working on the rear again.

 

Just weld them all together.

We do 90ft.lbs on ubolts, but that can still happen. Just a part of the leaf spring lifestyle. Ubolts should always be torqued on the ground

 

I remember a kid in high school said he did just this to keep it from happening. Said he ran a small bead down the side at the center pin. Thinking back on that I don’t really think it is the best idea

 

um, guys?

 

Haha I was absolutely joking about welding them together

 

Oh I’m sure you were. But this kid in high school wasn’t. Although I never inspected his truck to verify. I do recall him saying that and it made me think then. Now it would really be a head scratcher if I actually saw it

 

I mean, if it works... Hahaha

 

Speaking with Kelly at DMZ a couple years ago, he said to torque down the u bolts to whatever they’re spec’d for - they have a chart by size from deaver, and re torque them once you’ve driven around a few miles until they’re good.

 

What springs are they? And how much bump travel? If it’s 3” or better they are going negative. SOA is just so damn flat it don’t take much.

 

They are U402IIs. I have about 4.5” of bump travel. So yes, with the geometry of SOA, they are probably going slightly negative. My setup is full archive and it’s nice for what it is, but I want more bump travel.

 

At 4.5" you're going big time negative. Mine are U402's as well. At least half of my 4" of uptravel is negative arch.

 

Any consolation but my Deaver U402III's do that too with the bottom 2 leaf's. Ive left them alone since theyre not hurting anything, ive hammered them back in place but after a hard day on the dunes they just move to being mis-aligned again. Ive got 3.5" of up-travel so like stated above its most likely from being negative

 

Y’all are silly sometimes trying to generalize things. Bump travel has nothing to do with how far your leafs go negative. Think about it. Take your truck with let’s say 4” of bump travel at ride height. At full bump the leafs on that truck are going to go so flat or negative based on the geometry of the suspension and length of the main leaf right.

Now take the same exact truck and throw 2 motorcycles in the bed. Now it only has 2.5-3” of bump travel. But at full bump the leafs aren’t going to go more negative than before.

Generalizing and saying that having more than 3” of bump travel means your leafs go way negative is totally the wrong way of thinking about it. Suspension geometry, leaf length, and leaf pack height if soa are the factors which actually matter.

 

Hate to say it, but it is generalized when using factory geometry. I too run hammer hangers and a shock relocate on deaver U402's. Really the only thing dictating the severity of negative arch is the bump stop. And thats why we all have different bump travel numbers. Mine start going negative around 2" of bump. And I'm sure everybody else's does as well considering there is no real difference in setups.

Onto the issue of leafs sliding off center.

But still, do you have the same ride height as him? Same bump stops (stock style or hydro)? Hydro will bump higher up than a stock style if set up correctly.

What I’m saying is just stating bump travel numbers is a generalization and not very accurate. 2 trucks with the exact same suspension setup but different weight rear bumpers or weight spare tires will have different bump travel numbers but will still go the same amount of negative arch

 

I have Deaver U402 Stage 3's leaf's with King Hydro bump, archive hangars w/ 3.6 shackles and shock relocation for conversation sake

But regardless of bump travel numbers, with SOA were going Negative at very similar points
