 Q.Why do I need to change shock absorbers at the same time as springs?
Shock absorbers and coil springs work together keeping the tyre in contact with the road. If the coil spring fails it will place extra stress on the shock absorber, therefore to maintain good tyre contact with the road, shock absorbers should be replaced at the same time, in axle pairs.

| Q.Why do I need to check suspension geometry after fitting new springs?
As springs fatigue and sag, caster, camber, toe and the turning circle are affected, therefore, a full geometry check after fitting new springs will reduce wear in tyres, track rod ends etc. |
|
| Q.Why should replacement spring always be fitted in axle pairs?
Although one spring may have broken and requires replacing, the other springs will be fatigued and failure may be imminent. As with shock absorbers, replacing just one spring will result in an un balanced axle which will manifest itself with uneven braking and handling. |
|
| Q.Why are coil springs which come off a vehicle often longer than the new springs supplied as replacements?
Because the old springs have become coil bound. They have stopped returning to their original height following extensive compression |
|
| Q.How do I adjust a Gas-a-Just shock absorber?
The name of this product refers to an internal self adjusting valve mechanism. It is not possible to manually adjust this shock absorber. |
|
| Q.Why are shocks for OE and aftermarket sometimes different?
Because OE shocks are designed according to manufacturer specifications for a brand new vehicle. For the aftermarket, the shocks are designed to compensate for the fact that other components on the vehicle are likely to be worn and KYB wants to restore the way the suspension performs to how the manufacturer intended. The main differences are the damping force and the stroke length. |
|
| Q.What kind of controls do KYB use during production?
Everything is controlled concerning both quality and tuning parameters. For quality, KYB tests design specification, component quality, production line quality. For tuning parameters, KYB tests piston
orifices, valves, piston ports, nut torque settings. |
|
| Q.What kind of oil is used in KYB shock absorbers? Does it vary depending on the climate?
KYB uses the same specially designed oil in all its shock absorbers, regardless of the area they are to be used.It is made from mineral oil, with patented additives and catalysts. It takes into account:
durability, performance at both low and high temperature, and low friction. |
