I believe that the kid, 300EX powered by monster has 400ex arms on his 300ex. As far as I know Honda hasn't changed the geometry at all on the 400ex.

The arms will make your quad wider a little in the front if you use the stock 300 shocks the geometric angle of them will be different I'm sure and you will me sitting lower. i'm putting 400ex arms on my 250X later on but I am buying the shock conversion kit from Diamond J Customs so I can add the 450R shocks for a better ride. you may also have to remove the bracket that holds the brake line in place to account for the width.

You may also need longer brake lines. I don't know but maybe.

True... but i think I read on Dimond J's site that you can either buy the extended lines or just simply remove the bracket so they won't bind up.

Right on. When I put my +2 stem on, I almost ran out of brake line. My bars are kicked forward a tad bit more than I prefer, but I think I'm getting some Flex Bars that have a lower rise.

If you are putting on longer a arms, that means your hubs are further out. You very well may need longer tie rods.

The 400EX is 2" wider than the 300EX. So you are looking at +1" on each A-arm. They might fit but you won't have much thread availabe for adjustments. I would play it safe and buy the correct ones.

Agree^^^^^ Where are you buying from? if you go to Ebay and do a store search for GDH Racing this guy has all grades of quality Honda ATV parts anything you need if you don't see it shoot him a message he will respond promptly. He also has great prices.
