IMO I would get your frame work done and assemble yourself. Save money and you know every part is greased like it should be. You'll know that all bolts are tight Ect. Motor size doesn't make your build a different one. A build is a build. I have recently got some fireball stuff lately I was very impressed with their work. Stage 5 elkas are great shocks along with some others like fox Ect. Just make sure it's setup for your weight and what your doing. Even when the shocks are setup for your weight if you choose elka for a example, your gonna have to adjust the collars down to your liking. Your doing a cover build? Your gonna want to stay stock length or -1
