Confirm the Engine Is Ready for a Refresh
Check the cylinder bore, pistons, crankshaft journals, connecting rods, valve guides, and valve seats before installing the new parts. If a major component falls outside its service limit, consider the Polaris RZR 900 Engine Rebuild Kit instead.
Follow the manufacturer’s clearance, ring-gap, valve-seat, and torque specifications during assembly. You can also review the REV6 warranty policy or contact our team for help selecting the appropriate RZR 900 kit.
