Hey guys , just wanted to find out if the Monroe Original Gas Shocks any better then stock .. cause i wanna also use them for Lowering around 2.5inch drop ?

im guessing they were made basically like standard shocks , but should they be abit better and can used for lowering ??!!

can anyone help me out !

cheersss :):)

i got them on my eg..better than stock for sure..but dont expect performance

thanks for the info man , yea just want sumthing better then stock .. are they even made for lowering tho ? cause stock shocks sag heaps, dont know abt this one ?

cheers

I heart the SSS

Monroe is ok, isn't too bad

With good springs they handle better then stock, but don't compare them to Koni's etc.

try KYB Excel G, they are a great shock and when coupled with a good spring = fun

nah not comparing them to koni's , just wanted sumthing cheaper then koni's .. for ride purposes and some performance wise .. im probaly getting K-mac springs 2.5inch drop ?

how much do KYB go for these days ?

cheers

im running KYB Excel-G's in my EG with King low's. stiffer than OEM for sure, but yes as mentioned above gives you fun. you might need to replace your bump stops too, mine were shot

I would also go for KYB, as it apparently has valve design to resist lower than standard cars... this was on the GR2 model (USA) which from what i'm lead to believe is the same as thr Aussie Excel-G release...

Monroe gas and gt are pretty decent but don't expect them to last long overly lowered because it means your shocks sit in a more compressed stance than what it's supposed to which lead to leakages earlier....

general rule of thumb though... at the end of the day damage is primarily done on really bumpy roads

cause stock shocks sag heaps

"Shocks" (i.e. dampers) don't "sag" to any significant degree, almost regardless of what quality they may be nor how worn out they become. When you get noticable 'sagging', it's the springs (or maybe bent components) that will be the cause, not the dampers.

Dampers with pressurised gas effectively have a 'spring' rate because the compressed gas acts like a weak auxilliary spring, and these can lose this effective 'spring rate' if the gas pressure is lost. However, this pressure is fairly low and thus contributes only an insignificant amount to the overall spring rate (the great majority of which comes from the springs themselves), and thus has no significant affect on ride height whether the pressure has escaped or not.

Most 'gas' dampers are 'low pressure gas', but there are 'high pressure gas' dampers (typically much more expensive) where the gas pressure may well have a more significant affect on ride height should the gas pressure be lost. However, high pressure gas is unlikely to be found except in quite expensive specialised racing dampers, not in the more commonly available products being discussed (even Konis are low pressure dampers).

Which is because of the damper being forcefully bottomed out repeatedly, more so on bumpy roads. However, the damper can still be destroyed by a single harsh bottoming out event...

Dampers aren't more prone to being damaged at low ride heights because of the lower ride height itself, unless they are being hammered by bottoming out, which often occurs more readily at lower ride heights if the spring rate is not high enough.

A lot of people shorten their bump stops when fitting lower springs, but IMO all this really does is expose the damper to increased danger of being destroyed. If you need to cut the bump stop to get some clearance and reasonable suspension travel, then what this is telling you is that your ride height is too low or the damper body too long, or both....

This is why KYBs (and others like Koni which are probably out of budget) have the dual compression system... theres a seperate nitrogen gas chamber for said low pressure and an oil chamber for heavier duty stuff.:thumbsup:

yeah it wont sag as bad as oem shocks..so its better..and also i got them off wrekeres 60 for 4corners..with king lows..

"Dual compression system"? I suspect you might be mis-understanding the purpose of the gas pressurisation. The pressure exists in all interior parts of the damper and is not there to intentionally contribute any ersatz spring rate or "compression" resistance (the fact that it does, to a very small degree, is co-incidental and more or less irrelevant). The pressure is there to pressurise the hydraulic damping fluid and thus reduce airation of the fluid in use.

The pressure reduces the tendency for gas bubbles to form as the hydraulic fluid is forcefully (very) passed through the damper valves. If more than a few bubbles form in the fluid then it starts to become a froth, which passes through the valves with very little resistance, which does not do good things for the damper's performance...

Dampers ("shocks") don't sag, springs do.
