NASA P/G Input Shaft w/Turbo Splines & Rings

The NASA P/G Input Shaft w/Turbo Splines & Rings is a precision transmission component designed for builders and mechanics who are upgrading or rebuilding Powerglide transmissions. This input shaft is a crucial link between your engine's torque converter and the transmission's planetary gearsets, making it essential for maximizing power transfer in high-performance applications.

Manufactured from high-grade steel by Transmission Specialties, this input shaft features turbo splines and rings that ensure positive engagement with both the torque converter and transmission internals. The turbo spline design provides superior holding power compared to standard splines, reducing slip and improving efficiency under load, which is particularly beneficial in turbocharged or supercharged engines.

This component is ideal for high-performance rebuilds and upgrades, ensuring reliable operation under demanding conditions. Its precision machining and robust material selection allow it to handle higher horsepower levels without wear or spline degradation, maintaining shift quality and power delivery consistency over time.
