Clutch Disc 10.5x1-3/16-18

The RAM CLUTCH Clutch Disc 10.5x1-3/16-18 (SKU: RAM1358) is a rigid-hub, sintered iron clutch disc engineered for high-performance automotive applications requiring precision engagement and reliable torque transmission. This 10.5-inch diameter disc with 1-3/16-inch by 18-spline hub design delivers the durability and consistent friction characteristics that modern performance engines demand, whether in street, drag racing, or off-road competition environments.

The sintered iron friction material provides superior heat dissipation and wear resistance compared to organic alternatives, making it ideal for sustained high-torque scenarios. The rigid hub construction eliminates compliance issues and ensures positive engagement without chatter, delivering predictable bite and smooth modulation across a wide range of engine speeds. At 5.75 pounds, the disc maintains the mass characteristics necessary for proper flywheel balance while supporting aggressive driving demands. The 1-3/16-inch spline diameter and 18-spline count are universal specifications found across many performance platforms, allowing fitment on standard clutch housings designed for this interface.

This clutch disc serves engine builders, performance shops, and enthusiasts upgrading factory clutch systems to handle increased power outputs or improve shift responsiveness. It is equally suited for street performance applications and dedicated track use where consistent friction coefficients matter. The sintered iron material resists fade under repeated aggressive launches and maintains engagement quality across temperature extremes—critical for both cold-start reliability and sustained high-load operation.

Universal clutch discs in this size and spline configuration are industry standards for mid-size V-6 and V-8 platforms, as well as turbocharged four-cylinder applications. Verification of fitment compatibility with your specific vehicle's pressure plate, flywheel, and input shaft is essential before purchase. This is a single disc unit and does not include a pressure plate, release bearing, or flywheel—those components must be confirmed or sourced separately as part of a complete clutch system assembly.
