450r Rear shock

My 450 rear shock is out of the quad. I can measure from eye to eye and how thick the mounting points are. You could then measure the same on yours. That will tell you if it will work.

You probably can't use the linkage.

By not using the linkage on a swingarm that uses linkage you are drasticly changing the geometry.

I don't doubt that it would fit like that. That would make the quad sit really high. My bottom mount on the shock sits level with the bottom of the swingarm. By not using linkage you would raisee the back about 3".
