I havn't bought 400EX/250R shocks for my 250R a-arm conversion on my 300ex. AS is now it sits exremly low with the stock shocks and I need longer ones. When my a-arms are all the way down it leaves about 15" of room for shocks my stock are about 13". I can use a shock up to 15 1/2" how long are the stock 400EX or 250R shocks. Or if they are to long do you know of any other quads with a shock that will work maby LT250R.
