High-Performance Valvetrain Control

Take your Big Block Chevy to the next level with the T&D Machine SportComp 1.80 ratio shaft rocker. Featuring a .050 RH offset, this rocker is designed to provide the precise geometry required for high-lift camshafts. By moving to a shaft-mount system, you effectively eliminate the instability of stud-mount rockers, allowing your engine to rev higher and more reliably under load.

Key Technical Features

• 1.80 Ratio: Designed to maximize valve lift for improved cylinder head breathing.
• Shaft-Mount Architecture: Provides a stable, rigid platform for consistent valve timing.
• Full Roller Tip: Minimizes side-loading and friction for increased longevity.
• Premium Aluminum: Lightweight design reduces valvetrain mass for faster engine response.
• RH Offset: Engineered for perfect alignment in specific BBC head setups.

The T&D Machine SportComp series is built for those who refuse to compromise on quality. These rockers are the perfect choice for high-horsepower engines where valve train stability is non-negotiable. By maintaining exact rocker geometry, you ensure that your camshaft profile is fully realized, resulting in better power delivery and reduced wear on your valve train components. Trust in the precision of T&D Machine to keep your engine running at its peak. Find all your high-performance valvetrain needs at GGCRACING.
