Frequently Asked Questions

What compression ratio does my engine need for these cams?

The 570C is tuned for engines with compression ratios between 9:1 and 10:1. Check your build specs before ordering.

Will these fit my 2005 Dyna?

No — these cams are for 2006 Dyna and 2007 and later big-twin models. Earlier Dynas use a different cam profile.

What's included in the kit?

Both camshafts, cam bearings, gearcover gasket, and installation instructions. No additional parts needed for installation.

Do I need a tuner with these cams?

Cam changes often benefit from fuel-air tuning, though the stock ECU may work acceptable depending on other modifications.

Are these suitable for high-performance riding?

Yes — the 570C profile works well with the improved hydraulic chain-tensioner system found on 2006+ Dyna and 2007+ big twins.
