A stabiliser ensures that the vertical movements made by one wheel are ( to a lesser degree) also made by the same wheel on the other side of the vehicle. This will lessen the amount of leaning in bends and reduces croswind sensitivity. A ( heavy duty) stabiliser is particularly recommended for vehicles with a high centre of gravity
Fitting heavy duty shock absorbers will ensure that the vehicle movements in relation to the road surface are absorbed quicker and better. The bodywork will return to its ride height sooner after each movement. Vehicles with soft suspension are generally found to be comfortable but often demonstrate unstable road holding. By fitting heavy duty shock absorbers the stability will improve and therefore also the safety of the vehicle.
