I have a 2006 yamaha grizzly 660 and 14" itp c series wheels with 27 inch xtr mudlites. My issue is when i hammer the throttle the tires rub on the back of the floor board HELP!!!

 

Try adjusting the shock spring to the stiffest setting. Hoe much air pressure are you running in them???

 

Same problem either need to lift the quad, aftermarket shocks will help or trim the fenders

 

I had the same prob. on my Griz with 27" bear claws on if you look at my pics you will see where I cut mine they work good now and only hit if I really bottom out .I did stiffen up my shocks too. Check pic # 6 and also note the home made splash gaurd on the floor board I made it to keep the snow from comming up on me, a little cheaper than overfenders for know.

 

Yeah i am prolly going to lift the quad and trim the fenders also but if i only lift it will 2" be enough?
