Shock absorbers gas or hydraulics which is better for air ride and why?
I have always like the hydraulics better than gas but the last two sets that I've got you could push it in with no back pressure at all, it was to pull it out that it required a lot of power, it seemed to me that when the tire bounced it will go up automatically and that's when it need the shock absorber to produced some back pressure not when it's going back down.
Gas or hydraulic which is better?

anybody?
Bump. -
think of a basketball, if you don't force it back to the ground then it does not bounce. same with tire. catch the force and dont let it return to bounce again.

A 50/50 hydraulic shock does a good job of dampening a rough road, however a gas charged shock is better at keeping the tire in contact with the road surface for better vehicle control. Todays technology focuses on the latter. If you prefer hydraulic over gas you could shop for 50/50 hydraulic shocks instead of just taking what they have to offer. I'm not familiar with other hydraulic shock ratios other than 50/50 for a truck or the reasoning behind them.

gas shoks loose gas in 1-2 years and run worse hydrolic but do not leak.
So with gas shoks you need to check it on vibro tester every year to find bad one.
Bad hydrolic shok leaks oil -
gas charged shocks are designed to not fade as fast on bumpy roads. They help prevent the oil from foaming. Once you loose the gas in the shock, they fade quickly.
Shocks have a service life too. Can's say how long depends on your driving area. -

Thaks every one for your imput, I don't mind replacing shocks every year, so if gas are better but their life span is about two years, I think I'll go back to them and just raplace'em every time I get new tires, which is about once a year.
