BC0905 – Polaris XP 1000 (14-up) Stage 5 Race Only Camshafts (pair)

High lift, big duration spec for high compression (12.5:1 minimum) racing applications like Short Course or Drag Racing. Pulls hard up through 9900 rpm with emphahsis on the top end. ECU flash or tune recommended. Due to high lobe lift, it is mandatory that you change the valve guides and use BC valve seals. Failure to do so will result in retainer to guide contact causing damage to the head and/or cams.
