Rev6 offers quality parts that are proven to last. We stand behind our parts with a 1-yr warranty.

Fits the following applications:

  • 2018-2020 RZR 900 engines (all models)

Rev 6 cylinder head will include:

  • Rev6 upgraded manganese bronze valve guides (retain their size, better heat dissipation and longevity)
  • Upgraded forged one piece nitrated valves (stronger than OEM, better rev count, performance and longevity)
  • High temp, performance valve stem seals
  • Modified cam caps for additional oiling to the top end
  • Rev6 cylinder heads will come complete with cams, shimmed and ready to install!


We set all valve lash looser to accommodate for lap in time. This will help reduce the need for shimming after the break-in point.

Some deductions may affect getting a full refund on the cylinder head, depending on damage.
