Hydraulic vs. Gas Charged Shocks:
All automotive shocks use hydraulic fluid in them.
The shock transfers the energy of the car's motion into heat and then dissipates the heat
out through the oil into the air. To make a hydraulic shock into a gas charged shock
they inject gas (usually nitrogen) under pressure into the shock.
Gas charged shocks provide a sportier ride.
This is the result of the gas pressure inside the shock which forces all air out of the oil
and away from the shock valve. This is important because air compresses and oil does
not so the response is quicker in a gas shock because inside a hydraulic shock the air
must compress before the oil can be forced through the valve.
Hydraulic shocks give a softer and smoother ride.
This lag in the response is what gives hydraulic shocks the smoother ride feel compared
to gas charged shocks. Both shocks have the same strength but the resistance
is increased at a slower in the hydraulic shocks which produces the softer feel.
Classic cars were designed with hydraulic shocks.
If your car is a classic or vintage car it was designed with hydraulic shocks.
Our hydraulic heavy duty and extra heavy duty shocks will provide
the closest to the original feel that the car had.
