Gas shocks are designed with nitrogen gas inside of them. These are more equipped to fit smaller cars and can take a beating from the road’s hardest and most severe bumps. Generally, you’ll find newer cars are fitted with gas shocks.
These are ideal for larger trucks, Jeeps, or SUVs, and if you want to go off-road or need to haul heavy loads. These typically have a larger central shaft and give your vehicle a firmer ride.
As the name suggests, air shocks are powered by pressurized air. The air works by inflating inside the shaft, raising or lowering them when needed. They are generally quieter than standard shocks but are more expensive.
These types of shock absorbers are more commonly seen on motorcycles and scooters. They feature a spring coil wrapped around the shock cylinder.
