300EX front End?

[TeamTaylorRace]

Will 400 EX A-Arms fit on a 300 Ex. If so what is the difference in lenght between the 300 and 400?

SEARCH!...i believe they will be like +1 1/2 wider. It will give you bumpsteer. You will be better off buying aftermarket 300ex arms..

I dont kmow what the with specs are, but I do know that if you are planning on running the 400ex shocks the shock mounting braket will need to be replaced. I don't know who makes them but I have seen them for sale on eBay alot.

The 400ex a-arms work good on the 300ex if your not a full on racer. If you do get the 400ex a-arms, your better off getting the aftermarket shocks for the 300ex and not the 400ex stockers, they bottom out to easily. And also, if you put the 400ex a-arms on you 300ex, and not the aftermarket one's made for the 300ex, you won't have camber and caster setting which is needed for a full race bike.

That's why I used this setup. 87 250r a arm with camber adjustable/replaceable ball joints, 250r ties rods and custom length Works(14.75"). It worked well but I have switched to aftermarket a arms made for the 300ex with Elkas:devil:

The entire front end is for sale if interested. $250 for Works, a arms and tie rods
