chain rubbing on laeger frame?

[Lynch01ex]

have a laeger framed R with a cr500 linkage. I had a 13 tooth front sprocket on it last year. This year i jump up to 14 tooth and now when shock is at full extension the chain rubs on the bottom frame rail. I really really dont want the chain chewing through my chasis. So my question is does any one have a fix for this? Is there a slider they make?Any of you guys have the same problem what did you do? Any help is greatly appreciated!
Thanks for your time

Try running a stock chain slider on the front.

Go back to the 13 tooth front sprocket and drop the rear sprocket a couple teeth.

I was actually thinking #13.
