Yes they will work fine under a tourer. You will need to let us know what the intended use is for so we can build them accordingly. You will still need to tune them to your liking.

Definately worth consider, they are extremely well built and are specifically made and valved for what you are wanting to do. They are also adjustable which makes them a great option for a good 'all-rounder' rig. At elast you have local support and full backup, mick has all the parts to custom make/supply any variation to suit, and he always stands by his gear!
has any body got these yet on there car?
im keen but just the price kinda sets you back a bit.
cheers mick

Or if money is no object! then he can supply Kings Race shocks, so skys the limit....

whats involved in "tuning" them?

Yep and its that 30% that only needs to be put in the right conditions to go blammo...

Do u still believe that your car runs on diesel/petrol?

In reality as a ratio, your car runs on air.... but uses a fuel as a catalyst to burn the air

lol
:rofl: I just reread what you wrote it makes sense now :rofl: I think mythbusters should test that theory of filling gas shocks with air and see what happens when they get hot :)

You can tune them with nitro psi, adding or removing shims "valving" and oil viscosity.

So is it something that i can do on the bench at home? do they come with the shim thingys? do they come with the instructions on how to tune them?

Yes these can be rebuilt at your house with a few basic tools.
Yes they do come with shims already. We usually build them valved heavy "unless specified" that way you have more shims to play with.
We are working on step by step directions with pictures. But rebuilding/valving is a lot easier then people think.

Yes rebuilding is easy for guys who know shocks, valving is by no means easy for a person who is not in the shock industry.
Sure it is easy to undo a stack of shims but to then work out if out of say 10 shims you should be replacing which shims and what thou dia and thickness is way over the average persons skill.
Plus every time the shock comes apart the seals should really be replaced , not to mention the regassing every time, removing the shocks and refitting and test driving .

Most guys are not going to have access to Nitrogen either and they should not as the shock can be damaged if over charged.

Sorry for putting this negative post up but i think it is a far call to say valving and shimming is easy.

Most guys would not even have the tools to open the shocks or clamp them in their vise , or have a clean enough work environment.

Shock guro's like brad from Kings in brisbane did not just get things right the first shock he played with it is 20 od years and he is still learning.

Not knocking products here but my opinion is valving and shoimming should be left to experts. ;)

You can use oxygen to fill a air shock, it dosent go bang. I belevie they use nitrogen becouse is dosn't hold any moisture in it and its expantion shrinkage rate is low with heat ect.
Im only a humble chippy thoe who specialises in wood ;)

The reason nitrogen is used is it prevents foaming and brings up the working temperature of the oil.

I tidied this post up a bit as i got of topic on air shocks.

If you use compress air in an "AIR SHOCK" you will have a lot higher chance of getting contaminants in the shocks as it will probably have come from a compressor.
Oxygen will create rust if their is even the slightest moisture anywhere.

Well these turned up today

Now to mount them, should be an interesting experience ! :shock:

I spoke to chris about the REDBACK air shocks.... mmm very interesting.

I cant wait to get my hands on one to strip down and test. By the sounds of it they have doen some great development on these, and AFAIK they are fitted with a digressive piston and valve shim pack...........nice. The piston design also is supposed to have differential flow porting , so dampening characteristics are adjusted by the way the piston in installed - and complemented by valving shims.

I will let you know more when i get more info / pics.

yep can get almost any sizing. (sorry don't understand the '610mm' though? is that open length or closed length or stroke).

Emailed about these today.. turns out you cant get almost any sizing, unless its 708mm open length for front or 735mm for the rear...


heres the emial i got back

We only make them to 708mm open in the front and 735mm open in the rear.
And they are $440 each.

Luke is just a sales guy, and is not really up on them (afaik) Mick handles them directly as they are his babies. He does all the custom valving and setups, he can order/custom build to most sizes - chat to him directly!

I am interested to know what sort of travel you are chasing (obviously the longer the better). You said you are looking for 850mm front and 950mm rear, but what is the compressed length? This is more critical than the open as this determines exactly how big a shock can be. The SRC's are VERY effecient in open/closed lengths, especially compared to fox/king/saw.
As a comparison (for your front) a 12" fox has 790mm open and 485mm closed (then add pin/eye adapters) VS SRC 12.2" 708mm open & 400mm closed , which really saves modifying mounts on most vehicles. Similar in the rear.
What shocks (and sizes) are you running now?

Hey Greg, I am running 820's in the front at the moment, and i actually dont want any longer than that in the front.. i musta pushed a wrong button when i said 850's!

But yer at the mo im running 820 front and 1000mm rear. not sure of compressed lengths tho..! i will have toget the tape out!
