300EX/400EX Swingarms

Has anyone here ever tried attaching a 400ex swingarm to a 300 ex? I have a stock 400EX swingarm and a 300EX that needs to be longer.

Thanks

if you get the hole rear end out of a 250r it will fit, or even a 350x

quad shop extends them if im not mistaken??? it is less than buying another swing arn sale the 400 one and get them to extend your stocker... just thought

how'd you do that Ex'r Marlin?

I bought my 300 used with the modification already made to it. It looks like they cut the section off just behind the shock mount and added a two inch section and welded it back together. The mod looks very clean, and I have had no problems for the 5 years I have had it. It is a very noticeable difference riding a stock length swing arm and going to the +2"... It really helps keep the nose down!:) As well as being less bouncy in the whoops section.

hmm...... I wish I could find someone to do that, I'd have mine lengthened +1, Did it have a new shock on the back or just the stocker?

Stocker rear:) And I have no reason to change it.... For now anyway:) I find the rear stock shock on the 300ex to work great for me.
