Hi Gear Friction Clutch Pack(5)

The Hi Gear Friction Clutch Pack (5) from TCI is a high-performance transmission upgrade designed for racers and enthusiasts rebuilding or servicing Powerglide automatic transmissions. This five-piece clutch friction set replaces worn or degraded friction material, restoring shift quality, engagement precision, and overall drivetrain reliability in high-gear applications where consistent holding power is critical to performance.

Each friction plate measures 0.098 inches in thickness and is engineered with premium friction material formulated to withstand repeated engagement cycles and high thermal loads common in racing and street performance scenarios. The Hi Gear specification ensures these clutches deliver positive lockup in the transmission's high-gear band, enabling smooth power delivery without slip during acceleration or load transfer. TCI's friction compounds are designed to work in harmony with OEM and aftermarket drum assemblies, providing consistent coefficient of friction across a wide temperature range for predictable transmission behavior.

Powerglide transmission builders, drag racers, and street rod operators depend on these clutch packs to maintain tight band engagement and eliminate unwanted slippage during hard launches and sustained load conditions. Installation requires transmission disassembly and is best performed by experienced technicians or professional transmission shops. This set of five friction plates provides a complete replacement solution for high-gear clutch applications and is compatible with most Powerglide rebuild kits and valve body configurations. Verify band and drum compatibility with your specific transmission assembly before ordering to ensure proper fit and function.
