Hello all, I want to go greasless on my 2006 Grizzly 660. I run 27" ACT HD tires and pretty much stock. I do all trail riding below 30mph some mud some rock. Where is the best place to purchase greasless parts for the 660? Also thinking of installing an EPI orange secondary spring with the stock weights to see if I can get a bit more low end grunt. Any suggestions would be great. Thanks.
