i am wondering if i was to get a set of 400ex a-arms and put them on my 250x would they fit? would after market 400ex a-arms fit and would the shocks fit with out doing anything to the frame would after market shocks fit as well?

 

The stock 400 arms go right on to the 250/300. They are about 2" wider, makes an awsome improvement. The stock shocks are to long to fit right in the frame, but the are kits sold to raise the upper mount. In my photo page there is a 300ex with 400ex arms and a lowering kit, so you can see the stance and width.

 

wow thats a big improvment...but where do you go about getting one of these upper mount kit things

 

ebay has a bunch of them. I just saw one for the upper mount for 90 bucks buy it now.
