Are Car Shock Absorber Buffers Useful?
2 Answers
Car shock absorber buffers are useful. Car shock absorber buffers are generally made of rubber material and, like shock absorbers and suspension springs, 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. Meanwhile, the shock absorber refines and accelerates the attenuation of the spring's inherent vibration, and finally, the shock absorber top buffer conducts the final cushioning to the vehicle body. More details are as follows: 1. In car shock absorbers (including suspension springs), apart from the shock absorbers and suspension springs absorbing the vibrations and impacts caused by uneven road surfaces during vehicle movement, car shock absorber buffers can also provide a certain degree of shock absorption and cushioning effect. 2. For vehicles that do not come equipped with shock absorber buffers from the factory, the use of these buffers can significantly enhance the vehicle's vibration filtering quality and also contribute to noise control to some extent.
Recently installed a set of suspension cushions on my 8-year-old SUV, sharing some impressions. These are essentially rubber blocks inserted between the springs, mainly addressing squeaks and looseness caused by aging springs. Over time, spring gaps widen, causing metallic clunks when going over speed bumps. After installing the cushions, there's noticeable improvement in bump absorption, especially rear passengers reporting reduced sway. However, installation technique matters – misaligned placement can accelerate wear. Key point: if springs are already sagging/deformed, this is just a temporary fix. Recommended for vehicles over 5 years old – about $15 cost, 30-minute shop job, but completely unnecessary for new cars.
