Thanks to my knowledge gained in practice i was able to select THIS amazing performance shock absorber for my heavy-duty equipment .It has drastically improved the smoothness of operation and reduced vibration. The quality is top-notch, and its durability is unmatched. Moreover, the product is fairly-priced and worth every penny spent. The only downside I could think of is that it takes a bit of skill to install, but that's a minor con. This shock absorber is an excellent choice for those in the Industrial and Scientific field..
