BUT, inboarding the shocks allows room to fit a longer shock for better travel if the springs allow it.

Hey sierraDan, I know what it means/ how it's done. I want to know why
What does it acheive? What are the negatives and positives of this set up

My build shows how I did it. I have a lux commo shock combo and the lean softens them up. Plus I get extra flex.

Positives: See above.
Negatives: You have to move the top mounts. And they soften them up slightly (Good or bad depending on how the shock rides already.)

actually it changes the damping ratio by lots
I'm now running shocks with about twice the damping to match the front.
but yes it allows a lot longer shock to be installed

Inboarding the shocks effectively increases the amount of axle travel/for a given amount shock travel. Think trigonometry.
Due to the change in axle travel/shock travel the dampening rate of the shock is also effectively decreased.

so what is the advantage of inverting them rather than inboarding them or do you do the both together?

from what i can work out inverting them gets the body of the shock away from the axle tube.

And if you really need to do this, it would make sense to run them the correct way with new mounts.. Not all shocks are designed to work upside down..
I run mine inboard, helps clear everything better.

My rancho's cease to do anything while upside down.

Well they absorb shock. But they're shit. Only reason i still have the rear ones is because i dont wanna buy new shocks now, when ill need longer ones in a few months.

You can buy bolt in kits from lowrange for cheap.. Or make something to bolt up for even cheaper. Or just weld a new cross member in..

X2 a lot of shocks do't work at all upside down, or the valving gets VERY VERY soft.
The adjustable ranchos I have here are pretty good for what I do. I would prefer a gas charged shock, but find one that is adjustable is really hard to do.
I carry enough weight to drop the rear end to the bumpstops sometimes, and then sometimes I am empty. I also drive everywhere I wheel and then drive home, so a different valving for road than highway is nice to have.
I have the knob shocks though, not the new 9-way air operated.

This whole "inverting" thing brings the lolz.
The term was somehow dreamed up by retarded hilux owners who thought that rotating their shocks from running fore-aft to across the car was (a)cool and (b) "inverting" them.
WTF.
The rear shocks on a SWB Sierra are already freakin' "inverted" based on what the hilux mouth breathers reckon.
If inverted actually means what it's supposed to mean, i.e "turning the shocks upside down" then only mono tube gas and remote reservoir shocks work upside down.
If inverted means "leaning the tops in" then yes it can work, assuming you are prepared for the loss of damping rate. A shock at 45 degrees will be 40% softer than the same shock vertical.
I know this stuff was mentioned across a couple of posts here but it can't hurt to reiterate it.

You got a smile out of me Steve, thanks for clarifying it and getting it all in one post.
One thing I would like to mention is that leaning the shocks in will also cause a bit of body roll.
Think about the shocks at the end of the axles, and the end of the body. Now when you hit a bump going around a corner, all that weight from the momentum falls on the very outside of the axles, and the weight it is bearing is from the body at the outside.
Now imagine top of the shocks are in the center of the body. Go around that same corner and hit that same bump. Now the body will pivot over that spot on the body the shocks are mounted to.
Once you get enough force to start the body leaning, tuck one side down, and have the inside of the body come up, the weight pivots on the shock mounts, and transfers over to that outside and there is nothing on the outside of the body to dampen it. Kind of like a teeter totter on the play ground if you know what I mean.
Code: Like this

Versus
_________ /\
If the body can move around/tilt those uprights, it is obvious which one will be more stable on angles and around corners. If you consider the loss in effective dampening that Steve pointed out, that makes it even worse.

LOTS more body roll! roundabouts became hard to drive because i was near in the passenger seat haha.

And to stop that loss of dampening you run a heavier shock, I use patrol rears and there quite a comfy ride...

I'm running patrol shocks 10degrees in/10degrees forward and it's stiff

The Lowrange kit only fits SWBs. The LWB (either Sierra or Maruti) have slightly different spacing and the Lowrange kit will need to be modified.
