First Drive Clutch Disc

The First Drive Clutch Disc by BRINN TRANSMISSION (MPN 71021) is a premium rear clutch friction disc engineered for high-performance manual transmission systems. Built for drivers and mechanics who demand reliability in modified or racing transmissions, this clutch disc serves as a critical component in power transfer from engine to drivetrain. Whether you're upgrading a street machine or maintaining a competition gearbox, a quality friction disc directly impacts engagement smoothness, holding capacity, and overall drivability.

Designed specifically as a rear friction element, this disc works in conjunction with pressure plates and flywheel assemblies to create the clamping force necessary for torque transmission. The friction material composition is engineered to withstand repeated engagement cycles while maintaining consistent bite characteristics across a wide range of operating temperatures. At 0.3 lbs and measuring 4.15 x 0.25 x 5.25 inches, the First Drive Clutch Disc integrates seamlessly into BRINN TRANSMISSION systems, offering precise fitment that eliminates slippage and chatter during launch and acceleration.

Mechanics and transmission builders favor BRINN components for street rods, truck builds, and off-road applications where clutch durability is non-negotiable. This rear clutch disc is ideal for customers rebuilding BRINN transmissions or performing routine maintenance on existing installations. Proper installation requires careful alignment during assembly to ensure even pressure distribution and prevent premature wear. Stock this friction disc for inventory or order individually for direct replacement—a single disc covers one application per transmission rebuild.
