Brian Crower Stage 4 full drag spec camshafts are the top tier grind for an all-out, high rpm Polaris RZR Pro R (21-up) build.

Why it holds up

  • Advertised duration (.020"): 276°/276°
  • Duration @ .050: 252°/252°
  • Valve lift (1:1): .460"/.460" (11.68/11.68 mm)

Fits

  • Polaris RZR Pro R (21-up)

In the box

  • Camshafts (pair)

Good to know

  • Requires a BC spring/retainer kit.
  • Because of the high lobe lift, you must change the valve guides and use BC valve seals. Skipping this causes retainer to guide contact that damages the head and/or cams.
  • Must run aftermarket pistons with proper valve reliefs. Cannot run with stock/OE pistons because of possible piston to valve contact.
  • ECU and cylinder head work will add to overall performance.
