New rocker arms (cam followers) are required during any new camshaft installation on the S54 engine. Otherwise the original rocker arm will wear the new camshaft lobe unevenly. These are the Original BMW S54 rocker arms and used on the original E46 M3 CSL cams as well. While these are fine for CSL cam upgrades or the Schrick 280/272 cams, the Schrick DLC rocker arms are better all around, especially when used with the more aggressive 288/280 or higher cams.
Priced per rocker.
