CAUTION: The shock absorber and spring assemblies must be changed in axle sets. Failure to follow this

instruction may result in damage to the vehicle.

The additional weight of the armour on the vehicle means that certain parts have needed to be uprated. The
service life of many of the suspension components has been reduced due to the increased vehicle weight.

The armour vehicle is now fitted with shock absorber and spring assemblies to accommodate the extra
weight of the armour.
