M30 Forged Steel Rocker Arm Set

Set of 12 heavy duty forged steel racing rocker arms by KM Cams for the M30 engine. These rocker arms have a wider pad for better camshaft contact. You'll no longer need to worry about the potential failure of cast aluminum rocker arms when upgrading to these steel rockers. We recommend these along with performance valve springs.
