Perhaps, your Pontiac shock absorbers including its springs are commonly the most misunderstood, yet a critical part of any car suspension especially on off-road driving. It is the Pontiac shock absorbers’ job to control the car’s suspension. A shock absorber typically contains a number of parts: the shock body keeps it simultaneously and contains the shock oil, the shock shaft extend beyond from the shock body and connects the piston at one end, and the suspension arm at the other.
Shock seals hold all the oil on the inside where it really belongs, whilst the volume compensator makes allowance for the oil that is dislodged when the shock shaft and piston go into the shock body. What comes from the resistance of the piston to moving through the shock body that is filled with oil is the “damping” effect of a shock absorber.
In addition, a Pontiac shock absorber uses different valves and springs to adjust the dampening force of the shock. The shock will perform according to the three types of valving characteristics: progressive, linear, and digressive. Progressive shocks start out soft and get stiffer quickly as the shaft speed increases while linear shocks which is somehow similar to progressive valving yet does not make dramatic changes at higher speeds uniformly increase stiffness as the piston speed increases. In digressive valving, it starts out stiff and eventually it tapers off.
Because the shock in a progressively valved shock is softer at slower piston speeds, it will produce a better ride quality. Forlornly, a digressive shock will provide a harsher ride for it is stiffer at slower speeds. However, it has also its advantage; it offers more stability because it takes a lot of the body roll out of the car, which improves the corning ability of the vehicle. In a linear valving, the ride quality and car control is average because linear valving is predictable.
