They play a key role in balancing the car by sustaining the weight of the vehicle and absorbing the road vibrations.
They ensure a longer life to shock absorbers and the whole suspensions system, keeping the right contact between tyres and road.
DID YOU KNOW...
Coil Spring are responsible of:
STABLE STEERING AND ROAD HOLDING WITH TYRES, SUSTAINING THE VEHICLE UNDER ALL CONDITIONS
Hit and vibration absorption:
FOR A HIGHER DRIVING COMFORT
Reduced stopping distance:
ENSURE A SAFE BRAKING DISTANCE
A DEMAGED AND WORN SPRING DECREASES THE NORMAL HEIGHT OF THE VEHICLE IN TIME.
Why replace THEM
Coil Springs may be subjected to damages due to:
Corrosion and rust due to climate factors such as humid weather or cool temperature;
Small collision or impact with debris material of roads;
Impacts can damage the external coating, increasing metal corrosion. A worn and rusty spring has a greater risk of breakage, due to the strong stresses which reduce over time the ability of the spring to return to its original size.
Therefore it is important to replace springs and shock absorbers at the same time, always by the same axle in order to restore the optimal state of the suspension and balance the vehicle.
Features and checks held on the product complies with the OE standards
Raw materials and processes can be tracked and are certified in each step of production.
Hot coiling technology
Powder ink spraying and high temperature solidification thickness
Thickness and coating tests + salt spray test to check corrosion resistance of the spring.
OP Coil Springs are available in 4 variants:
Linear: with constant flexibility.
Progressive: spring flexibility increases with compression.
Side Load: their curved shape reduced the friction between shock absorbers piston rod and seal, increasing the life of shock absorbers
Miniblock (taper wire): this model with barrel shape is extremely flexible, allowing a higher driving comfort. This spings is typical in cars models such as Audi A3/A6, BMW serie 3 VW Golf and Passat.
