This fully liquid cooled 84 mm cylinder is machined from billet aluminum and finished with tough nickel silicon carbide plated bores. Put it on top of a stock Polaris RZR engine and you’ve got 840cc of nearly unstoppable power. Machining the cylinder from billet offers increased wall thickness and improved coolant flow. An added bonus is there’s no core charge. The cylinder is offered as a kit (with 84mm pistons, rings, pins, clips, head and base gaskets) or by itself. A Billet cam, lifters and valve spring kit are also available.
Designed for 08-2014 Polaris RZR 800.
