Quality & Core Details

Our double inspection guarantee means two master technicians check your engine—one assembles it, and another inspects it. As a result, your Polaris RZR PRO XP engine leaves our shop better than new. A refundable $1500 core charge applies unless you return your old core. Once it passes inspection, you receive the refund in full.
