Good To Know

Q: How do I confirm this kit fits my machine? A: Check that your model is a RZR S 800 EFI within the 2008-2014 range and that the bore matches your existing cylinder. Verifying the part against your machine before ordering prevents a mismatch.

Q: Should the cylinder be measured before installation? A: Yes, measuring the bore and checking piston clearance before assembly helps confirm the parts are within spec. Following the recommended torque and break-in procedure supports a longer service life.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
