Clutch Pressure Disc Steel

The clutch pressure disc steel (MPN 71017) is a critical wear component designed for high-performance and custom transmission builds, particularly in Brinn transmission applications. This precision-engineered pressure plate serves as the spring-loaded clamping mechanism that engages and disengages clutch friction material under extreme load conditions. Whether you're rebuilding a vintage hot rod, a drag racing platform, or a custom street machine, the clutch pressure disc steel is essential for reliable power transfer and smooth gear engagement.

As the clamping force component in a manual clutch assembly, this pressure disc uses spring tension to hold friction material against the flywheel, creating the mechanical grip needed to transmit engine torque to the transmission input shaft. Steel construction provides superior heat dissipation and durability compared to stamped iron, making it ideal for applications requiring repeated full-throttle engagement or sustained high-rpm operation. The compact dimensions (4 x 0.4 x 5.1 inches) and lightweight profile (0.13 lbs) are engineered to minimize rotational inertia while maintaining structural rigidity under clamping loads, directly improving shift response and reducing drivetrain shock.

Mechanics and builders specializing in transmission overhauls and performance clutch systems will find this pressure disc essential for Brinn transmission rebuilds and upgrades. It works in concert with friction discs, flywheel, and release mechanism to deliver predictable engagement feel and maximum power capacity. Proper installation requires accurate alignment and correct spring preload adjustment; consult your transmission assembly manual or professional builder for specific torque specifications and setup procedures.
