Break bad on the trail, ride the most buggy-busting terrain you can find - Trail Armor's new ultra high density plastic a-arm guards can take the iMPACT! Made of the same 1/2" ultra high density plastic we make our skid plates out of, these are by far the toughest, best designed and coolest a-arms on the market. Guards have three sided protection of your front and rear CV boots - front, rear and bottom - and mount easily with no drilling required. All mounting hardware and simple photo-documented installation instructions are included. Fits Polaris Sportsman ACE 325, 570 and 900 2014 - 2018. Will not fit the 2017 and up ACE 900 XC.
