they got it, puts your ass over the tires for more traction, and makes you swing around easier in the corners, most people like -2's, but some use -1's to
the ones they do make from metal, are aluminum, not steel, the epoxy ones (i ran one for a year) work just as good, mine took a hit from a chain skipping off and didnt go through the epoxy i think it would take many more hits from chains
i swapped mine because i just didnt feel jarms were up to par with the aarm models being for every quad out there, just to weak. Now if i was running a sand drag bike, i would be all over a jarm quad.
