General information regarding the fitment of shock absorbers, suspension struts and lowering kits.
Replacing shock absorbers on any vehicle requires mechanical automotive experience. Under no circumstances should any tool be used to grip the piston rod. This will inevitably produce damage to the smooth surface of the piston rod and torn chamber seals, resulting in fluid loss and an unserviceable unit. Please take time to examine other suspension components during fitment and renew any worn items with suitable replacements.

Suitability
Be sure to check that the parts you are supplied are suitable for the vehicle for which they are intended.We cannot replace any items that have been correctly supplied to the information that we have been given after they have been fitted.

Springs
Please ensure that springs are fitted correctly and not inverted. If you are unable to determine the correct fitting position for your vehicle please refer to your workshop manual or seek guidance from a qualified person.

Brake bias adjustment
Some vehicles that are fitted with a brake bias system may require resetting or adjustment after installation of your new shock absorbers and springs.

Mechanical ABS sensor adjustment
Some vehicles that are fitted with mechanical ABS sensors may require resetting or adjustment after installation of your new shock absorbers and springs.

Steering geometry
Unless Gaz Shocks specify alternative measurements, please use the settings detailed by the manufacturer of the vehicle.

Lowering measurements
The reduction in ride height quoted in our catalogue is approximate and can be affected by many factors that are outside the control of Gaz Shocks. Please ensure that your car has not been subject to any other conversion that may continue to influence it’s ride height after installation and impair the performance of our product.
N.B With some Mercedes models,worn spacers between the coil spring and spring pan may result in excessive lowering. Replacement spacers are readily available from Mercedes Benz spares stockists and should effectively remedy this problem.

Problems associated with excessive lowering
Gaz Shocks recommend that no vehicle is lowered more than 60mm.We will not accept any claim for damage or excessive wear to any component or area of a vehicle however caused.

Vehicles that have had their ride height reduced in excess of 40mm often benefit from having their steering geometry reset to the data detailed by the manufacturer of the vehicle to promote even tyre wear. In some extreme cases even this course of action will not remedy the situation and Gaz Shocks cannot be held responsible for any excessive tyre wear however caused.

After market wheels & tyres
Please ensure that the wheels and tyres fitted to the vehicle will allow enough clearance from the bodywork after installation of the lowering kit. Gaz Shocks are not responsible for any damage to tyres or bodywork caused by friction during contact.
