Is Installing Shock Absorber Buffers Useful?
2 Answers
Automotive shock absorber buffers are generally made of rubber materials. Like shock absorbers and suspension springs, they can assist in providing shock absorption and cushioning effects. 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 suspension spring. Simultaneously, the shock absorber refines and accelerates the attenuation of the spring's inherent vibrations, with the final cushioning transmitted to the vehicle body via the shock absorber top buffer. Below is an introduction to shock absorber buffers: 1. Principle of Shock Absorber Buffers: They feature a spiral rubber design and are installed in the middle of the suspension spring. When the car corners and the center of gravity shifts to one side, causing the vehicle body to tilt and compress the spring, the buffer provides support, thereby reducing the car's body roll. 2. Overview of Shock Absorber Buffers: The buffer is a highly elastic and durable rubber product, classified as an automotive modification accessory. It is installed at the spiral spring of the car's suspension system, primarily serving to cushion shocks and protect the shock absorbers.
I've helped friends install shock absorber buffers a few times, and from my observation, they do provide some extra cushioning, especially for older vehicles with slightly loose suspension systems. After installation, driving on uneven roads feels less bumpy, and there's an improvement in comfort. However, these things aren't perfect—if the size isn't chosen correctly or the installation isn't precise, they can cause uneven stress on the suspension, accelerate shock absorber wear, and even lead to strange noises or oil leaks. What's more troublesome is that long-term use might speed up tire wear, affecting driving safety. I think if the car's suspension is in average condition and it's just for short commutes, temporarily installing them for relief is acceptable. But I wouldn't recommend them for new cars or owners who frequently drive on highways, as the drawbacks might outweigh the benefits. It's best to have a professional mechanic check the car's condition during maintenance to ensure they don't cause hidden issues.
