Tailshaft Seal/Bushing TH350/PG/Bert/Brinn 10pk

The Tailshaft Seal/Bushing TH350/PG/Bert/Brinn 10pk from ALLSTAR PERFORMANCE is an essential maintenance and upgrade component for serious drag racers, street performance builders, and transmission specialists working with high-output powerplants. This product is designed to refresh and service TH350 transmissions, as well as Bert and Brinn direct-drive units.

Tailshaft seals and bushings prevent fluid leakage, reduce friction at the output shaft, and extend transmission longevity under sustained load and heat cycles. They isolate transmission fluid from the external environment, preventing contamination and loss of hydraulic pressure that can compromise shift quality and accelerate clutch wear. Additionally, bushings support the output shaft, reducing radial play and vibration critical in high-horsepower applications.

This 10-pack bulk quantity makes it economical for shops, race teams, and enthusiasts who service multiple vehicles or maintain inventory for customer builds. The universal-fit design ensures compatibility across multiple transmission families, including the TH350 and modern performance units like Bert and Brinn direct-drives. These components are ideal for both street and race environments where reliability is paramount.
