IMHO the Primax doesn't ride as well as the Neway, but then again the Neway's I've drove aren't setback front axles, so not really a fair comparison.
It rides better than the KW 8 bag in the otherwise exact same truck.
I find it quite stable, even with really abnoxious loads. The Neway's that I thought are more stable also have right and left side leveling valves, so that isn't a fair comparison because I did that to an old Pete with Air-Trac and the change was noticeable.

Here is the two things I cannot stress enough about the Primax

1) It is a true 4 link suspension. 4 links build traction under torque by their very design, if you do any off-road, traction issue type of work, this is a major advantage. I have been in shi#t that I can't believe I made it through with this truck that I know my previous trucks would not have done.
2) If you do multi-axle work and have to "drop your jeep and chain up" frequently, it can be an expensive suspension to maintain. That's why I kept shifting the OEM style tie rods, ugly work loads/conditions with 70k on the drives...these "ball" type just take it.

I would really like to try a Neway suspension truck spec'd the same as this one to see if it really is the back end or the front end that makes the difference on the ones I've drove...

Short version, I love its traction ability, I'm not sure if I'm just delusional about the ride part, because it's never been a "true comparison".
