Polaris RZRs swept the podium at the Ultra-4 MetalCloak Stampede at Prairie City SVRA near Sacramento, Calif. this past weekend. Rain and mud made the course that consisted of rock obstacles, tight turns, jumps, whoops and open sections even more technical and tough.  Paul Hart in his RZR XP Turbo EPS would take the checkered flag with Phil Cagliero, also in a RZR XP Turbo EPS, in second, and Ryan Bersamini in a RZR XP 1000 EPS took third.
