McPherson struts at the front (shocks and springs together in one unit) Gas shocks at the rear
It has gas pressurized shocks in the front and rear.
A 2002 GMC Yukon XL with autoride can use regular gas shocks. However, they are not recommended for use on the autoride, instead you should use autoride gas shocks.
Hydraulic and gas charged shocks have the same amount of oil, the difference is the gas charge. A hydraulic shock has equal amounts of dampening force in both directions. Gas charged shocks usually are pressurized with Nitrogen. Hydraulic shocks have a tendency to fade as the oil heats up and gets agitated by the shock, creating air bubbles. These air bubbles cause the shocks dampening ability to fade. The nitrogen charge keeps the air bubbles under control, so they can not affect the shocks performance. A gas shock will extend on its own due to the gas charge. General rule of thumb is that hydraulic shocks ride better, nitrogen charged shocks are stiffer, but last longer and don't have shock fade problems.
Gas shocks are considered better and are usually more expensive. They use pressurized nitrogen to absorb shock, as opposed to hydraulic which uses an oil. The oil in a hydraulic shock may foam under heavy use and lose efficiency.
The problem with the 24" rims is they're heavy, if you put air shocks on your car it will and I assure you, you will have an unpleasant ride. But if you are going to put gas, it will compensate for the offset of the rims but make sure you will put the best gas shocks and not the cheap ones because it will wear out easily obviously because of the weight compensation and the off set
Depends on what you're driving. Most cars have gas shocks and some have air shocks. Air shocks are more comfortable, with an automatic leveller, as in Lincoln Continental, in my opinion.
Typically Nitrogen in factory produced shocks, Or compressed air in motorcycle adjustable air shocks.
Back in the 1940's and earlier you could rebuild the hydraulic shocks in many vehicles but since then they cannot be rebuilt, just replace with a new one.
Automotive shocks and struts are charged with Nitrogen gas. Automotive air condition systems are charged with r134a refrigerant gas.
Hi test , is the engine rebuilt ?
Trunk props,or prop rods. They are "gas struts"
