I would say no to respond to your question ACSRACING: unless your doing some super intense rock crawling or something. The reason it is needed for the long travel kits is because the longer you extend the arms out the more leverage it has on the frame and mounting points sometimes causing them to bend or break as we have seen above. If your word some companies also provide support kits kinda like the one above but in bolt on fashion not weld in. Obviously i would assume the Weld in ones will be the strongest though. But to respond to your question with out Long Travel you should not need the gusset kit.
