I've noticed a lot of talk of fitting landi shocks to the rear of the 300.

No real problems there with doing that other than the rates are not right by a long shot. The real issue is everyone looks to be fitting the cheapest basic oil filled units rather than go going for a gas pressure one. Maybe the gas ones are just way to stiff?

Surly a gas pressure non adjustable damper that is intened for teh 300 would offer much better results even if a little more expensive than the landi ones. I know the adjustables are out of reach price wise for some but I would have though propper gas pressured dampers for the 300 series would be affordable?

So you can use a standard shock but add more gas? How would someone go about this?

I *think* the ones off my GLS are gas as they are relatively stiff for standard, moreso than I've ever seen on any 300.

You dont add the gas, you have to buy the standard ones with the gas in them

I've got uprated monroe landy's for mine called "4x4 adventure" lol, charged to 25bar >.< I think it might be a little bit too stiff haha

i have gabriel gas riders on mine but there soft and springy? thats why im going for landy shocks

Fox do some units for landies, id get them

I have been looking into how gas shocks work, but i dont understand how they improve things. The gas allows the oil to move and does mean it has to displace the shaft of the shock. Could someone explain how this adds a real improvement?

Just to put my oar in re gas shocks.

Basic principle of a shock damper (or at least) the types that we normally see is to control the movement of a road wheel by allowing oil to pass, through a metered orifice, from one chamber to another. Contrary to "popular" belief a damper contributes verrrrry little to suspension stiffness and nothing at all to ride height. (a damper will however contribute rebound stiffness).

The problem with moving oil through a hole is that produces heat - as does the absorbsion of suspension energy. This heat together with the rapid oil movement tends to cause cavitation (in simple terms bubble formation and foaming) in the oil which will rapidly degrade the dampers performance. This is the "failing" of conventional oil filled shock absorbers.

Gas dampers are still oil filled and the oil still provides the damping medium - BUT - the oil is placed under gas pressure (usually nitrogen) which greatly reduces the tendency to cavitate.

Gas dampers will have far less advantage in, say, a track day or drift car where suspension movement is relatively small than in a rally car where suspension movement is much greater and the cavitation producing loads are far higher.

I did not know that. So really, "gas" vs oil would not necessarily mean a difference in ride quality.

Not until you start giving it some, if you would want to on standard suspension The gas dampers will stay on form for longer

Ye, what mac said is exactly what i thought it did, my question is how much you would notice the degrading and how quick it happens.

No, it's all down to numbers. A damping rate is a damping rate, no matter what you use to achieve it.
