Will 250R a arms fit a 400ex?

[LiftedSahara]

I was wondering if Lone star +1+1 a arms would fit my 400ex or any 250r extended a arms for that matter? I am looking to buy a used set and was curious. Thanks.

I think the spindles might be different though.

they don't just bolt up. THe spindles are different material but same geomatry. THe only thing you need to do is grind down the part of the a arm that mounts to the frame. They are alot longer on the R. Its a pretty serious thing. And you could screw up a a arm. if your not careful. I am positive of the info I just gave you because i did it with some roll 250r a arms. Now they are on my buddies 400ex. I used em for a season without a problem. And now my buddy is using them
