Brian Crower Stage 5 Race Only camshafts for the Polaris RZR XP 1000, sold as a pair, are a high lift, big duration spec for high compression racing such as short course or drag racing. They pull hard up through 9900 rpm with the emphasis on top end.

Why it holds up

  • Advertised duration (.020 in): 276 / 276 degrees
  • Duration at .050 in: 254 / 254 degrees
  • Valve lift (1:1): .460 / .460 in (11.68 / 11.68 mm)

Fits

  • Polaris RZR XP 1000 (14-up)

Good to know

  • Race only. Built for engines with 12.5:1 compression minimum.
  • Changing the valve guides and using BC valve seals is mandatory because of the high lobe lift. Skipping this causes retainer to guide contact that damages the head and cams.
  • An ECU flash or tune is recommended.
