Diaphragm Cover

The Diaphragm Cover from RAM Clutch (MPN 9903) is a precision-engineered component designed to protect and regulate the diaphragm spring assembly in clutch systems. This cover is essential for mechanics and enthusiasts who are rebuilding or upgrading clutch performance, whether for classic vehicles or high-performance builds. Its role in maintaining proper spring tension and preventing contamination is crucial for consistent clutch engagement and overall drivetrain longevity.

Engineered to withstand repeated thermal cycles and mechanical stress, the diaphragm cover balances structural rigidity with lightweight construction, which is vital for reducing unsprung mass and enhancing throttle response. Weighing 2.96 lbs, this cover integrates seamlessly into complete clutch assemblies, ensuring reliability across various applications, including street, strip, and track. The precision manufacturing guarantees zero runout and consistent spring rate delivery throughout the engagement envelope.

Ideal for anyone performing clutch replacements, upgrading to performance pressure plates, or rebuilding worn assemblies on manual transmission vehicles, the diaphragm cover requires careful alignment during installation to ensure even engagement with the release bearing. This attention to detail is essential for optimal performance and longevity of the clutch system.
