If the rear of your car sits high and/or when you drive the rear suspension feels very hard and bouncy, then you need to replace these rear gas spheres. They work in conjunction with the rear shock absorbers to provide a smooth ride and also adjust the rear standing height of the car which varies depending on weight load –  how many passengers you are carrying and/or luggage in the boot.

The price is for 1 unit and you need 2 for your car (left and right rear shock absorber)

* NOTE: These look a little like the hydraulic accumulators but are not the same part and as such NOT interchangeable
