Dual Friction Clutch Disc GM 1-1/8 x 10-Spl.

The Dual Friction Clutch Disc GM 1-1/8 x 10-Spl. by Centerforce is a direct-replacement clutch disc engineered for GM vehicles requiring precise engagement and reliable torque transfer. This 11-inch diameter clutch assembly is purpose-built for drivers who demand smooth shifts without chatter, whether upgrading a street machine, restoring a classic Chevrolet, or maintaining daily-driver reliability. The sprung hub design isolates drivetrain harmonics while the organic and carbon friction materials deliver progressive bite—critical for consistent performance in both city driving and sustained load conditions.

Built on Centerforce's proven dual-friction technology, this clutch disc combines organic material on the primary friction surface with carbon composite on the secondary side, maximizing holding capacity while minimizing pedal effort. The 1-1/8-inch by 10-spline hub interface mates directly to OEM GM transmission input shafts, ensuring exact fitment without modification. At 5.42 lbs, the balanced rotational mass promotes smooth engagement transitions and reduces clutch shudder—a common complaint in worn or poorly matched assemblies. The sprung hub incorporates elastomer dampers that absorb torsional vibration, protecting synchros and bearings from premature wear while improving shift quality across the RPM band.

This replacement clutch disc is ideal for GM small-block and big-block applications, including Chevrolet, Pontiac, Oldsmobile, and Buick models spanning decades of production. Mechanics and enthusiasts choose Centerforce dual-friction discs for both OEM restoration and performance upgrades because the design tolerates higher sustained loads than stock while maintaining factory-smooth engagement characteristics. Installation requires only a clutch alignment tool, pilot bearing inspection, and standard flywheel removal—making it accessible to home builders and shop professionals alike. Verify 11-inch diameter and 1-1/8 x 10-spline hub compatibility with your specific GM transmission and bellhousing before ordering.
