Helix 5.5" (140mm) Sintered Drive Plate

The Helix 5.5" (140mm) Sintered Drive Plate is designed to transmit engine power through a racing clutch assembly with fast engagement and reduced rotational mass. Its sintered metallic friction compound bonded to both sides of a metal disc provides high friction characteristics with low inertia, helping you achieve quicker engine response and improved acceleration in demanding race conditions.

Discover the key features of this sintered drive plate:

• Sintered Metallic Friction Compound: A thin layer of metallic friction material bonded to both sides of the drive plate delivers high friction performance with consistent engagement characteristics, helping you maintain reliable power transfer during repeated high-load clutch operation and improving throttle response during acceleration.
• Low Inertia Construction: The lightweight metal disc design reduces rotational inertia within the clutch assembly, allowing the engine to gain and lose revs more efficiently which supports sharper engine responsiveness and improved vehicle control during gear changes.
• 5.5" (140mm) Clutch Compatibility: Designed specifically for use with compatible 7 ¼” (184mm) clutch cover assemblies, this drive plate provides accurate fitment within compact racing clutch systems, helping you maintain proper clutch operation and installation compatibility.
• Outer Plate Extended Hub Design: The outer type drive plate uses an extended hub configuration suitable for single plate clutch applications or outer positions within multi-plate clutch assemblies, allowing you to configure your clutch setup correctly for your transmission and driveline arrangement.
• Inner Plate Short Hub Design: The inner type drive plate features a short hub for back-to-back installation in multi-plate clutch systems, enabling correct spacing and alignment within compact multi-plate racing clutch assemblies for dependable operation under sustained use.
• Wide Range Of Spline Options: Available with multiple spline configurations to suit a broad range of gearbox input shafts, these drive plates allow you to match the clutch assembly to your drivetrain specification for accurate installation and dependable engagement.

Reduced clutch inertia and strong friction performance help you achieve faster engine response during acceleration and gear changes on circuit race cars. The compact 5.5" design supports lightweight clutch assemblies where space, rotational weight and driveline response are important factors in vehicle setup. Adding the correct Helix sintered drive plate to your clutch system provides a practical and reliable solution for maintaining consistent power delivery in demanding race applications.
