I could probably search it on here where I did a more precise calculation of it. But my memory is that the KDSS piston is about 20mm diameter shaft. With 500psi in the accumulators it would have a downward force on both pistons of about 300lb. That doesn't translate to 300lbs of lift because it still has a lever arm to the axle that will make it less net lean. I'd have to do a beam force calculation, but my memory is that it would be something like 100ish lbs of force at the end of the sway bar resulting in around 1/2" net lean to the passenger side if there was no suspension correction with stock 180lb/in rear springs and 580lb/in front coils. It's not a lot of lean.
