Product Description
We designed these rocker arms to be extra thick on the adjuster side to eliminate the fatigue failures which are common with weak OEM and Febi factory rockers. They are polished and shot peened with no casting marks, and use standard BMW adjuster hardware. You can see the differences in the pictures (HD rocker arm is the lighter colored one)
These fit both M10 and M30 engines.
M10 engine: order 8 rockers
M30 engine: order 12 rockers
