1.76 Low Turbo Input- Turbo Spline- 12.875in L

The 1.76 Low Turbo Input Turbo Spline 12.875in L transmission input shaft is a critical wear component designed for street and strip applications demanding reliable torque transfer through high-RPM power delivery. Built for Powerglide transmissions, this steel shaft handles the extreme loads generated by turbocharged engines, making it essential for serious performance builds where stock internals fall short. Whether you're upgrading a classic muscle car or building a dedicated drag platform, this input shaft is engineered to survive repeated cycles of boost and acceleration.

Constructed from premium steel and precision-machined to exact tolerances, the 1.76 Low Turbo Input shaft features a turbo spline design that maximizes contact surface area for superior grip and reduced slippage under full throttle conditions. The turbo spline geometry distributes rotational force more evenly across engagement points, reducing shock loads that can crack conventional splines during explosive acceleration or aggressive downshifts. At 12.875 inches in length and weighing just 2.27 pounds, this shaft maintains structural rigidity while keeping rotating mass minimal—critical factors for minimizing parasitic loss and improving overall driveline efficiency in competition-level powerplants.

Experienced transmission builders and turbo enthusiasts rely on this shaft when reinforcing Powerglide units for forced-induction applications where torque multiplication and shock load resistance define longevity. Installation is straightforward for technicians familiar with Powerglide disassembly, requiring only standard transmission tools and proper torque specifications during reassembly. This is the component you choose when stock shafts have failed, when boost levels exceed 8-10 psi, or when you're building a platform designed to live on the edge—buy with confidence knowing you're investing in proven durability.
