Master Versus Complete Top End Coverage
The Master kit includes the same cylinder, piston, and gasket coverage as the Complete kit, then adds four intake and four exhaust valves. If your existing valves remain reusable, compare it with the Polaris RZR XP 900 Complete Top End Rebuild Kit.
Technical Resources Before Assembly
Review the REV6 Piston and Ring Installation Guide before installing the pistons. Because this kit also includes valves, our article about valve guide failure in Polaris PRO-STAR engines can help identify additional cylinder head wear.
