Al-ko IRS Shock Absorber (Blue) is suitable for IRS axle groups only. Blue shock absorbers operate in reverse to standard shock absorbers and are therefore ineffective for beam axles.

How to replace shock absorbers

The Alko blue shock absorber is held into place with two bolts, it is a relatively easy operation to remove them. To test rebound simply close a fully opened shock absorber. If your IRS shock absorber closes easily then it needs replacement.

The tell-tale signs of a worn shock absorber is the degree of stone chips. These stone chips can puncture as mention before however, they are an excellent indication of shock absorber wear.
