Muzzys Home / Products / RUV Performance / RZR Performance / RZR Big Bore Kit

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 RZR engine and you've got 850CCs of nearly unstoppable power. Add the billet crank & rods kit and you'll have a 900cc Turbo Killer. NOTE: This kit will also fit the Ranger XP 800.

Machining the cylinder from billet aluminum offers the following advantages over similar kits that use bored cylinders with steel sleeves.

  • Increased wall thickness and improved coolant flow.
  • No sleeves to separate from the cylinder wall
  • Aluminum transfers heat better than steel for improved cooling

The cylinder is offered as a base kit (with 84mm pistons, rings, pins, clips, head and base gaskets) or by itself. The 900cc kit includes all the components of the 850 kit plus: a Billet crank & rods kit, spacer plate and two base gaskets.
