Long Travel BS Thread

Holy shit im used to seeing your truck airbourne. Question answered.

 

Haha, most of my local buddies drive jeeps with tons and 40’s, or the 4800 car lol. Few years ago we drove 800mi each way to the rubicon, drove the trail and drove home. It does “moderate” crawling trails amazing

 

Your rear setup is custom correct?

 

I’m sure he’ll correct me if I’m wrong, but Ryan’s setup started life as a DMZ kit, still uses the springs I believe, and then he redid the rear mount with a large flipped shackle arrangement. Definitely works well from what I saw at Cinder hills

 

Correct

Nailed it

 

I have that. Archive hangers and shock relocate with Deaver stock location spring under springs U644. Pulls a lil over 12in travel, maybe more once i change my bump setup. Works really good. I would do an inverted shackle if i could start over (probably will eventually)

 

Finally somone running it...any cons? Hows your ride height? How are those springs? I never carry any substantial weight and never tow, i dont even have a hitch.

 

Springs are too short and the ride is harsh @RonRon23

 

Even with a light duty spring?

 

What do you intend to use the truck for primarily? We established that full long travel spring under trucks can still wheel if you’re trying to build a “best of both worlds” rig. I researched mid travel SUA for about a year which led me to the conclusion that the ride quality and performance doesn’t justify the cost of upgrading from mid travel SOA.

Aside from cost, I found the biggest negative to be that the stock location spring under pack options are limited and not that great. Probably due to the spring length of the stock location? The lighter duty springs tend to sit flat. Deaver has the U539/540 HD that I’ve heard are harsh and have mixed reviews at best (not much arch or travel). I’m sure there are other options that work, but you have to know what you’re doing when setting them up because most of them are longer springs. At that point, I found it more reasonable to buy a kit that already locates new spring locations and cycles clean travel.

For cost, the DMZ and dirt king kits are impressive. There’s also the camburg kit, but a couple members have had issues with it eating bushings. I’m happy with my JD kit for how versatile it is, and I still get to keep my bed.

 

I was really happy with my 539/540’s when I had a 2” kit but once I did my 3.5” and really started pushing the truck it just wasn’t enough.

 

It's good for what it is. And good for the terrain on all the east coast i've come across so far (run out of space/power about the same time i run out of suspension usually). I'll second trekker that they're a bit harsh and the standard shackle travel is kinda an odd path. Like can't quite get that 'feels like nothing is there' feeling even with my shocks fairly dialed in. I run the springs with the very bottom leaf pulled and that puts me right at 6 up 6 down currently but it's just a tad too much spring for my trucks weight. Though my truck is very light so that's probably more of a specific issue with mine.
I mainly went this route because it worked out better for me to piece it together one piece at a time and this is still plenty for my use so far

 

The fact there are only 2 companies that even offer any sort of mid travel SUA says alot. The geometry of having a spring under the axle and keeping it under the frame rails always confused me.

I will stop asking questions I already know the answers to lol

 

They do fine, at least my JD rear works(HD Leafs) very well, I was on the fence if it would still take us over our typical trails but last outting it was rather surprising how well it worked, trail was moderately difficult with some pretty deep rutts and rock section.

 

I had archive sua with 539/540s. It was fine for running along with oem front. Loved weight, but unloaded was harsh for me. Never went light duty springs so I couldn’t say. Once I had the +4 up front and tried to push that, it was just no fun with the rear being unable to keep up.

Here's my buddy Travis wheeling his JD Sua + 2.25 kit on a local trail that's pretty gnarly. Pretty sure he's the first ifs truck to do it no winching.

Check the third clip in the sequence. He has other moments from that trail on his ig page.

 

Damn. That left rear wheel just sucks up in there so cleanly.

 

Love how the videos shows the passenger side shackle and leaf are on the log/pole and still able to move. This is exactly why I went JD fabs rear, no shackle hanger sticking down to hang up on.

 

Damn ya'll are making me wanna go spring under.
Even with MT front and a built out rear with alcan leafs and valved 2.0s, it's not totally copasetic.

 

Less axel wrap on SUA too
