The 390VCSPACER billet aluminum valve cover spacer provides additional clearance for roller rocker arms and performance valvetrain components on Honda GX270 and GX390 Non-Hemi engines. See full product details below.
The 390VCSPACER billet aluminum valve cover spacer is designed for Honda GX270 and GX390 Non-Hemi engines requiring additional clearance between the valve cover and valvetrain components. It is commonly used when installing roller rocker arms and other performance valvetrain upgrades that extend beyond the space available under the factory valve cover.
Many performance rocker arm systems will contact the factory valve cover baffle or internal surfaces during operation. This spacer raises the valve cover, providing the additional room needed for proper rocker arm movement and helping prevent interference that could damage valvetrain components.
Precision machined from billet aluminum, this spacer fits between the cylinder head and stock valve cover while maintaining a clean, professional appearance. The included billet aluminum center bolt replaces the factory bolt and completes installation.
Whether you're building a high-performance GX270 or GX390 engine, this spacer provides a simple solution for creating the additional clearance often required by upgraded valvetrain components.
