The SuperATV Polaris RZR 4 900 / S4 900 / S4 1000 Full Skid Plate gives your 4-seat RZR complete front-to-back underbody coverage in 1/2-inch proprietary ARMW. Each piece is laser scanned and CNC cut, and the patented interlocking design locks the panels together for a secure fit. Countersunk bolts let you glide over rocks and stumps. Choose your model below.
ARMW is SuperATV's blend of UHMW: stronger than stock, quiet, and resistant to bending, so brush and jagged rocks will not stab through your floorboard. Built-in drain ports make it easy to hose out mud after a sloppy ride. Patent No. 10,202,149.
This rzr 4 900 skid plate covers the 2015-2018 RZR 4 900 and the 2018 S4 900, and it is the rzr s4 1000 skid plate for 2019-2020.
