The Sonnax 28131 Reverse Clutch Pressure Plate is a heavy-duty component engineered specifically for use in GM Powerglide transmissions. Crafted with precision to OEM and performance standards, this pressure plate measures approximately 0.290″ thick, providing a robust surface that evenly distributes hydraulic pressure across the reverse clutch pack for reliable engagement.

The reinforced design ensures optimal clamp load is maintained under both standard driving conditions and high-stress, performance-driven applications, helping prevent premature wear and slippage. As a critical element in the reverse clutch assembly, the 28131 enhances the durability and consistency of reverse gear operation and is a trusted upgrade for Powerglide rebuilds focused on longevity and performance.
