Allstar Performance Tailshaft Housing Seal & Bushing – Bert/Brinn/Powerglide, TH350, Saginaw, Muncie

Upgrade or replace your tailshaft housing seal and bushing with this Allstar Performance unit, engineered for direct compatibility with popular manual and automatic transmissions. The assembly combines a rubber seal with a steel-backed bushing to provide reliable resistance to wear and help maintain precise tailshaft alignment during gear changes.

Designed for specific vehicle applications, this part is intended to be installed when you replace the tail shaft seal or after a driveshaft issue has occurred. The tail shaft bushing is a regular wear item located inside the transmission tail shaft housing, and keeping it in good condition supports smooth operation of the drivetrain.

Key benefits and use cases

• Rubber/steel construction balances flexibility with durable support
• Replace as part of maintenance when replacing the tail shaft seal or following a driveshaft problem
• Helps maintain proper tailshaft alignment, reducing the risk of leaks and unwanted play

What you can expect in real-world use: a straightforward replacement process during a tail shaft service, a compact package that fits inside the tail shaft housing, and ongoing reliability under repeated shifting and braking scenarios. While results can vary by vehicle and driving conditions, this part is designed to support consistent performance and easier future maintenance.

Installation tips

• Prepare the transmission area by cleaning the tail shaft housing and inspecting the seal surface
• Follow factory torque specs and use fresh seals when reassembling
• Check for any signs of wear or misalignment before completing installation

Designed to handle standard automotive temperature ranges and deliver consistent sealing with rubber resilience and steel backing, the unit can resist compression loss over time and maintain a tight tolerance within the tail shaft housing, even under torque loads.

Compatibility is broad but always verify the exact tail shaft setup for your model. This seal and bushing kit is intended for the listed transmission families, and installation may require basic hand tools and following your shop manual guidance.
