Shock absorbers are hydraulic oil pumps that absorb the shocks and vibration of the road surface while keeping the tires on the ground. A shock absorber is not a suspension system; it is a complementary performance part that assists the suspension system in both absorbing shocks while keeping the wheels on the ground. (The suspension system is used to support the weight of the vehicle while absorbing most of the shocks).

F-150 4X4 Shock Absorbers FAQ
Shock absorbers are designed to force the wheelbase quickly back down onto the ground for constant surface contact. A wheel in the air is a wheel the driver has no control over; this means a free-flying wheel cannot stop, accelerate or navigate unless it is in full contact with the ground.
There are several shock absorber categories on the market, these include:
- Twin Tube Designs:
- Gas Charged
- PSD (position sensitive damping)
- ASD (Acceleration Sensitive Damping)
Mono-tube design (Standard Types)
A monotube shock absorber has only one pressure tube as the name describes. The pressure tube contains two pistons, these are the dividing and working pistons. This model can be installed either way and will work perfectly. The m=difference between a monotube and twin-tube is that a monotube can add support to the weight of the vehicle, as such it more than complements the suspension. The other difference is that mono-tube shock absorbers don’t have a base valve. The piston controls the compression and extension. It’s a see-saw model, where the dividing piston moves up and down as the piston rod moves in and out of the shock absorber.
- Oil releases heat with less effort as the temperature rises
- No restrictions on installation angles
- Less prone to cavitation
- Larger oil capacity and greater heat dissipation provides a continuous stable damping force
- No foaming, air, and oil don’t mix; they are completely separated
- The piston valve is bigger and wider in a mono-tube design these give you a wider area of pressure
The twin-tube shock absorber has 2 cylinders. One cylinder is set inside the shell and the second contains the piston valve. The piston valve moves up and down in the second (inner) cylinder. These types have no barrier between the oil chamber and the gas chamber.
- External damage to the shell case does not affect the performance;
- The twin-tube design keeps the cost of production low;
- Gas pressure is kept low due to the base valve, which provides a more comfortable ride;
- Low gas pressure reduces stress on seals;
- Friction is at a minimum;
- Sufficient stroke is attained with far less effort.
Twin Tube – Gas Charged Design
The gas-charged twin-tube design uses nitrogen (generally) to reduce aeration of the hydraulic fluid. This prevents the oil and air from foaming when mixed. When aeration is reduced, the shock system works faster and reacts predictably for quicker responses. This assures the wheels are on the ground all the time.
Twin Tube – PSD Design
Position Sensitive Damping (PSD) is a fluid velocity control technology that considers the position of the valve within the pressure tube. This is reached through precision tapered grooves in the pressure tube that leads to two zones, the comfort zone for normal driving and the control zone for extreme condition requirements.
Twin Tube -ASD Design (Reflex)
Acceleration Sensitive Damping (ASD) goes one step farther than traditional velocity-sensitive damping. In this technology, you get to focus on impact by utilizing a new compression valve design. This is a mechanical closed-loop system that opens a fluid flow bypass around the compression valve.
