M311 Billet Rocker Stand Machined Finish

The M311 Billet Rocker Stand Machined Finish from Frankenstein Engine Dynamics is a precision-engineered valve train support component designed specifically for GM LS-series engines, including the LS3. This billet aluminum rocker stand combines OEM-level functionality with the durability and aesthetic appeal of a fully machined finish, making it an essential upgrade for LS engine builders and high-performance enthusiasts tackling top-end work or complete engine assembly.

Constructed from billet aluminum and machined to exacting tolerances, this rocker stand provides superior valve train support and alignment during engine assembly and operation. The machined finish not only enhances the visual appeal of an exposed engine bay but also provides protection against oxidation. At 0.98 lbs with compact dimensions of 3.45 x 3.4 x 18.5 inches, the M311 integrates seamlessly into tight engine compartments while maintaining the rigidity required for consistent rocker arm geometry and valve actuation. Frankenstein Engine Dynamics engineers this component to OEM specifications, ensuring proper clearances and fitment with LS-series heads and block assemblies.

This rocker stand is ideal for engine builders, performance shops, and serious DIY enthusiasts rebuilding or upgrading LS3 and other LS-platform engines. Whether assembling a stock replacement engine, a naturally aspirated performance build, or a forced-induction application, proper valve train support is critical for reliability and longevity. The M311 accommodates the specific rocker arm geometry of LS-series engines and is sold individually, so builders can purchase the exact quantity needed for their project. Its machined aluminum construction makes it a preferred choice for custom and show engines where both function and appearance matter.
