yes - exactly
and like i said, all i've got is a simple two bag system (one air bag or air spring over each rear wheel).
these are not shock absorbers but suspect folks that go for shocks to help control lean and some of the other negative ride attributes they're experiencing are mistaken in looking to shock absorbers for the answer. Shocks, from my knowledge (and i'm not the expert, so if someone knows better, please chime in) but shock absorbers, 80 - 90% of their true function is to dampen the spring's rate of return (after it's compressed from a road bump).
Best way to explain, when axle hits a pot hole or speed bump, it's the spring, whether coil or leaf, that allows the axle to move away from the load - once the spring has compressed as far as it's going to and the load (bump, pothole etc) are past, the energy the spring captured in compressing is used to return the axle to it's static or normal state. If the shock does not control that rate of return (rebound), the vehicle will "bounce". I'm sure there are enough folks on board here old enough to remember the cars back in the 60s, 70s and into the 80s - that 12,000 miles from new, when the shocks started to go bad, when they hit a pothole or bump, their car would still be bouncing a half block down the road. At State Inspections, procedure to check for bad shocks was to push down on the fender or bumper real hard and note how many times the car would cycle up & down before stopping - more than 1.5 cycles, car shocks were weak.
Kmessnger described how the original shocks wanted to stay extended where the koni's would compress manually and stay compressed. The original shocks were gas filled, which gives them that "spring" action wanting to return to extended state. In addition to the oil in the shock, that gas in the OEM shock acts in a smaller or lesser way, like an air spring - gas will compress, and in compressing is very progressive in it's rate of compression - ie first increment of compression travel might only take 40 lbs to compress it .25", the next .25" will take 65 lbs, the next .25" 95 lbs, and so on. So the gas or air bag, allow for a real soft initial compression step which takes the teeth jarring edge off the shock load, and then quickly, in progressive steps quickly firms up that resistance.
non- gas assisted shocks - first oil does not compress, so it limits compression on the shock only by being restricted by how much of a passageway it has to pass by the foot of the shock's piston as that piston plunges downward. Think of a old time barnyard water pump with a leather washer at the end of the piston - on the down stroke, when the handle was raised, the leather washer would fold out of the way to allow the piston to travel downward easily, then on reverse stroke it would remain flat and keep it's seal so that water would be pumped. Usually there's very little restriction on down or compression stroke in a shock absorber. The koni does allow for some compression control by the adjustment made by turning the piston (the chrome rod with the threaded end), it's adjusting or restricting those passages to a more restricted state. but on it's return upward, as the spring is pulling it, the return path is usually much more restricted, as it's true role is to control how fast the leaf or coil spring can release it's energy and how fast the axle is returned to it's static or normal position. and the size of the ports or openings in that foot valve plus the viscosity of that oil is what controls that rate of return. By turning the koni to it's firmest setting, the shock has been made firmer so it will affect lean or yaw, sway etc. But it can't do it as nicely as a gas shock or air bag being compressed does. unfortunately, the OEM gas shocks are not adjustable, like the konis, so the konis will have an advantage over them.
I was truly surprised at the ride in my tundra, both with and without wgt, after the air bags - much firmer ride control and yet nowhere near teeth rattling or what you would call uncomfortable - actually quite the opposite.
-i'm actually planning on one of the high end air bag kits with onboard compressor and 3 to 5 gallon tank to allow for automatically controlling side to side yaw or lean as those loads occur, whether from centrifigul force in a curve or high winds when crossing a bridge. Only caution, price on those systems seem to be strong, as high as $2,000+ for a really high end one but i've seen some interesing ones in the $1200 - 1500 range.
