The bellow construction and functionality

The assembly is designed not only to ensure the front wheels rotate, but also to create the correct angle when turning. In new car models, this is the most significant component of the transmission through which torque is transmitted. It is the CV joint that allows wheels to rotate evenly, therefore it must always be protected from dirt - this is what the CV joint bellows are responsible for.

To ensure efficiency, quality materials are used in the production, as well as silicone and neoprene compounds. This allows you to maintain strength, elasticity, resistance to water and negative environmental influences. In addition to the actual outer bellow, the kit includes an inner bellow, two sets of clamps, two retaining rings and two types of grease.
