Silent Blocs

Sale of engine silent blocks, triangles

Many different silent blocks for different car brands! Often wrongly called "cylinder blocks", silent blocks are made of rubber. We have selected for you silent blocks for engines, wishbones, suspensions, anti-roll bars, arms, axles, cradles, for a wide range of vehicle applications. These silent blocks have a very long service life and will improve the handling of your vehicle.

What is the role of the silent blocks?

Silent blocks are small components that play an essential role in keeping your car running smoothly. They are used to reduce the noise caused by the vibrations of the many parts of your vehicle and also to link certain elements, such as the shock absorber and the chassis.

When to change the silent blocks?

With use, the silent blocks become damaged and their thickness decreases. Rubber bushes often wear out more quickly because they are softer and the rubber can be altered by time and weather conditions, for example. This is why it may be worthwhile to invest in polyurethane silent blocks.

In general, it is necessary to check that the sagging of the soft part of the silent block does not exceed 2 or 3mm. For original silent blocks, the rule is that they should be changed every 80,000 km or so.

What are the differences between rubber and polyurethane silent blocks?

Rubber silent blocks have the advantage of being cheaper, but they have a shorter life span than polyurethane silent blocks because rubber is more fragile and more sensitive to external stress. The choice of material should therefore be made according to the use you make of your vehicle. For leisure use of your car, rubber silent blocks are sufficient. But if you want to improve your driving comfort or if you are looking for performance, for example in rally competition, polyurethane silent blocks would be much more appropriate.
