Can a Silicone Pad Be Added to the Shock Absorber Top Rubber Cover?
2 Answers
Yes, a silicone pad can be added to the shock absorber top rubber cover. Adding silicone to the shock absorber is beneficial. The functions of adding silicone include: 1. Automotive shock absorber buffer rubber is generally made of rubber material, which, like shock absorbers and springs, can assist in shock absorption and buffering; 2. During the operation of the shock absorber, the impact generated by the road surface is converted into the repeated bouncing motion of the spring by the shock absorber spring, while the shock absorber refines and accelerates the attenuation of the spring's inherent vibration, and finally, the shock absorber top rubber acts as the final buffer to transmit the impact to the vehicle body; 3. If the vehicle is not originally equipped with a shock absorber buffer rubber, the use of a buffer rubber can significantly enhance the quality of the vehicle's vibration filtering, and it can also help to some extent in controlling vehicle noise.
I've been driving for almost 30 years and have seen many drivers add silicone pads to the shock absorber top cover, claiming it helps cushion bumps or reduce noise. I tried it once myself back then, thinking it was a small investment to protect the components. However, the suspension system felt stiffer afterward, and going over speed bumps became noticeably harsher. Later, I consulted a friend who knows car repairs, and he explained that the factory-designed top cover is meant to balance the pressure and elasticity the shock absorber endures. Adding extra pads might actually disrupt this balance, leading to uneven stress on the suspension, accelerated wear, or even affecting steering. Looking back now, it's clear that such modifications shouldn't be done casually—risking potential issues isn't worth it. The best approach is regular suspension maintenance and replacing the top cover with genuine parts when needed, rather than cutting corners and taking risks.
