Description

138190030 Rocker Arm Fastening Bolt – For Honda GX200 & 196cc Clone Engines

OEM-style rocker arm stud for precise valve train alignment and reliable pivot action in non-Hemi small engines.


The 138190030 Clone Rocker Fastening Bolt serves as the mounting stud and pivot pedestal for stock rocker arms on Honda GX200 and 196cc clone-style non-Hemi cylinder heads. This hardened steel bolt threads directly into the cylinder head, securely holding the rocker arm in place and ensuring accurate alignment over the valve stem and pushrod.


As the rocker arm pivots during engine operation, this bolt provides a stable axis, helping maintain proper valve timing and lash clearance. It's essential for both stock rebuilds and performance applications where factory-style geometry is maintained.


Whether you're replacing worn components or rebuilding your top end, this bolt is a critical piece of your valve train assembly.
