OME ~9" front ~10.5" rear travel

So I did some measuring under my truck and realized the front OME shocks don't use about 30mm of uptravel measuring from the very bottom of the bump stop (absolutely no possibility to go father).
Also, if you look at the OME travel given their compressed length vs even really high dollar coil overs or shocks, the OME will give more travel for a given length than any of them.

I figured added a daystar 1.25" spacer (32mm, rember still havent acounted for the bumpstop any) and then used the 883 coil instead of the 885 (20mm longer) you would net about 12mm more lift than just the 885, so it's like adding the 13mm OME spacer. You add whatever up travel you lift by, almost an inch, but you gain potentially 30mm shock down travel, so about 60mm wheel down travel. This obviously would require brake lines and a UCA though.

In the rear the supplied shocks are really short, presumably to keep you from having to buy brake lines. It would be possible to run the OME 60066L shock in the rear which would give you almost 4" more droop. (I have wheels superbumps on all four corners and in the rear they are mounted on a steel bracket which is about 2" higher than the leaf pack. If you don't have these you could potentially collapse the shocks actually in my case and with the longer shock pin I could put a spacer there to get maximum downtravel). There are a few differences in the shock though, the bottom bushing is different, OME said they'd be glad to put the correct one in, and the mounting pin is 4mm larger in diameter. I suppose you might have to drill the frame, or what I would do is turn the shock on a lathe, the latter being definitively more involved but doesn't involve drilling. Anyone know the diameter of the rear shock mount hole off hand or has their truck apart and can hit it with a micrometer?

But if you already have UCA's and extended brake lines this is a $500 mod that gives you a lot of travel. Like I mentioned above, just in terms of pure numbers I think it beats a lot of the more expensive kits on the market and with the wheelers superbumps too it's a really solid mid travel kit for not that much, especially if you realize all this before buying the first time, then it's the same cost as the OME lift (plus UCA & brake lines)

Anyways, having this idea I contacted ARB about this shock. The US tech support didn't have any valving information so I contacted austrailia and this is what I have for you all...

Red is 60091 and blue is 60066L.

Curious what you all think of my super budget super travel mid-travel set up....

 

i can't wait for someone to soak the juicy-ness of this innn

 

pictures dont work.

How were you measuring. cus FYI the front bumpstops are at a different spot on the LCA than the lower attachment of the front shock. The front shock moves further up and down than the bump stop hit point.

In the rear. the 15.9in collapsed length is going to be likely too long unless you space your bump stop up a bunch... which at that point is pointless as you get rid of all your uptravel.

 

WTF is that supposed to mean?

 

I'm an automotive engineering student, thats about as far as i'm gonna go with that.

I already mentioned I have wheelers superbumps which have a base that approximately 2" high. I still have about 5.5 in uptravel. This setup would provide about 50/50 up/down in the rear.

You can get more travel in the rear than I've heard of anyone achieving using the stock shock mounting location and install a whole "mid travel" setup for less than 2,000, juicy, no?[/quote]

 

So the whole thing would look something like this

Front
brakelines
UCA's
Wheeler's Superbumps
OME 90000 front shocks
OME 2883 coils
Daystar 1.25" top spacer

Rear
Brakelines
Wheeler's Superbumps
OME 60066L shocks
Dakar Springs

Oh, also, Wheelers superbumps are really awesome, I have & love them. You can never tell if you actually hit the bump stops, their really pillow-y

 

How are the cv's with that front set up?

 

As long as you are not bottoming shocks before fully compressing bumps then go for it... FYI those wheelers super bumps compress a lot!! So you can just measure when they first initially touch.

Also FYI I deal with students in my line of work.... 90% of the time they cant make their head from their ass when it comes to real world applications... Not saying that's you but I take your statement with a grain of salt.

FYI the OME N182 was the longest rear shock I found that would not bottom before stock bump stops on a stock four leaf pack with a single add a leaf.

My measurements when flexed the setup above needs about 14.75 in min of collapsed length or less to be comfortable.

 

Lemme rephrase, a student with 3 years experience as a engineering assistant in the auto industry. All I'm saying is that I'm not just putting together measurements that don't belong together lol.

you mean maximum?
with the wheels superbumps I measured 16.5, about 2" as I said above.

 

I'm not running it yet atleast, statically they should be the same as running the 885 coil with the 13mm OME spacer.
The thing I'm curious about is down travel though... I'm not sure when the cv's or the tie rod ends would bind. or possibly UCA or sway bar contact.

I tried looking some stuff up about limiting staps but couldn't find any measurements.
I guess I would just have to try and cycle the suspension?

 

The sway bar is an easy fix...

 

I'm not gonna be trying to do this soon though because I'm gonna try and get a trd supercharger while I still can

I thought there might be more excitement about this arrangement/discovery with all the pretty graphics from OME

 

Go flex your truck. Tire in the air and measure. Your collapsed length.

 

that sounds like alot of effort... gross. why do that when i can do basic math? Also, i doubt i could get it to flex to the base of the bump stop. look at the fox coilovers though. their compressed length proves it would be okay.

fox shocks are 1.32 inches longer compressed length than ome, and presumably the max possible, confirming my calculations.

Anyone wanna keep challenge my ability to use a measuring tape?

 

Sure. Mostly because you're acting like a dick for some reason. Like a typical engineer (only you aren't actually an engineer yet).

As said, the potential issue with the front is binding of ball joints, tie rod ends and or CV joints at full droop with the wheel cranked. If you have issues with binding you'll have to limit the front. And you could actually end up with less overall travel.

More importantly, you don't have Dakars because you obviously haven't measured the droop with them installed. I do, and I have, my rear shocks are 10.3" travel. I will tell you that the shocks you're planning for the rear are too long to make use of their full travel. I had to use a jack to spread the springs just a touch to get my shocks in (about 1/2" longer than the dakars static droop). At static ride height, I had just a hair over 5" of my 10.3" shock shafts showing. Want to know how long my shocks are? Nah you're an engineer. Almost. You should be able to tell me how long they are right?

I also have the super bumps, front and rear. I have done a little measuring myself. No engineering degree but I can measure the fuck out of things. Lol

Even with a u bolt flip plate, you'll have to space the super bumps to be safe with those shocks. But here is a little hint.... With the upper overload in the dakars, you'll have to try damn hard to even touch the super bumps on the frame. I jumped mine a hand full of times and the big overload prevented the super bumps from touching the frame. I've since changed my spring pack to alleviate that. You're welcome for the heads up.

It's probably also worth noting that in a small truck without a lot of travel, I would choose quality of travel over quantity any time. A decent set of coilovers (even with less travel) will perform better than OME shocks in any situation that requires full travel (except slow crawling). And definitely anything high speed offroad.

 

Doesn't mean jack on this forum. I would take members' personal experience over any engineer's numbers.

It always looks good on paper until you try it out.
