Th350 Race Sprag

The TCI 328910 TH350 Race Sprag is a precision-engineered intermediate clutch sprag assembly specifically designed for high-performance Turbo 350 automatic transmissions. This component is essential for racers, drag-strip competitors, and street performance enthusiasts who require reliable one-way clutch engagement during hard launches and sustained acceleration.

The sprag operates as a mechanical one-way clutch, allowing the intermediate band to lock up instantly during acceleration while permitting overrunning during coasting or deceleration. TCI's race-spec design incorporates hardened steel rollers and precision cage geometry to withstand the extreme shock loads generated during full-throttle shifts and launch conditions.

This sprag is particularly beneficial for dedicated race cars and high-horsepower street performance vehicles, as it eliminates mushy engagement, reduces parasitic drag, and improves shift consistency across the entire RPM range. Installation is straightforward for anyone with intermediate transmission assembly experience, as the sprag seats directly into the intermediate drum and requires proper alignment during installation.
