find one with a builder backing their product and with a good metal. I have the burgard +2+1's on my banshee and love them... As for what kind to pick from its mostly just find a great deal... And as for shocks they can make or break you. The elka dunes are the best thing on my raptor and the eat everything. I have a group i ride with at glamis and three of them have gotten the elka dunes because they are great. but really any after market shocks are better then stock. just make sure you get some with Compression Adj, Rebound Adj and Preload Adj for the min. I put the yfz shocks on my banshee because i got them new for $150. and im just going to send them to my shock rebuilder guy and have them revalve it for my riding. Other then that. just stay with any old +2+1 arms and you should be good. and when you get he arms look over the welds and if they look like ass send them back and get new ones. There are guys that like the race there bikes in a line and other that like the carve and throw them over hills and jumps. Everyone that has or riden a stock suspension banshee knows that you cant ride very long. So mostly just use the search button because there are alot of reviews out there.
