I have a theory in my head that im trying to confirm with shock placement.

With the shock mounted behind the rear axle, it will counteract axle wrap better than if the shock is mounted in front of the rear axle. From what i have read, most off the shelf shocks are heavier valved for extension than compression. I guess it would come down to how the shock is valved and what it does under compression and extension.

I have a set of patrol shocks that will be mounted inboard, and will be alot easier in front of the azle. Been for a heavier vehicle they may provide enough even mounted in front of the axle. That is unless putting them on an angle reduces there effectiveness. Hope that makes sense. :?

Gwangensteve will be here shortly im sure to give an super answer.

But yeah, they dont work as well inboarded.

as you lay them over on an angle you decrease the valving rate of the shock.

Don't worry about the shock absorbers effect on axle wrap, its not their job. Even if they do somehow reduce it, as long as they are mounted the same distance from the axle centre they will have the same effect (all other factors being the same).

Just worry about the damping rate and lengths.

So a stiffer shock should be used when inboarding them in the rear?

Yours are almost horizontal aren't they?

Yea my rears are probably 100mm apart at the top but mount onto the top plate that holds the springs to the perches, new set up will be mounted on the axle and stood up more with taller mounts :lol:

Well that should mean the patrol shock should work alright in the back of a light zook... By the looks of it the tops will be around 150 - 250 apart. and the bottom mounts will move inward slightly aswell.

It depends on what your chasing from the shock.
my shocks are so long that if I stood then straight up and down they would likely sit 100mm through the floor so I run them lent over nearly 45 degrees.
but it makes the valving very very light, I'm good with the way it all works but I would be shitfull as a daily drive

yes you would need a very heavily valved shock to duplicate to correct stock valving if you lean them right over, but its all guess work unless you are capable of working the valving out

I am going to move mine in front of the axle when my old man gets back from holidays.

When we make the shock mount, we're going to make it so that the shocks can be mounted in a few different positions, I am only going to lean them over as far as I have to.

Part of this reason is that I want to do a U bolt flip, so the shocks are mounted right up out of the way. Ideally I'd do this on the front too, but I'll save that for later!
