PLANETARY TO CASE BEARING

The Coan Racing COA‑12431 Planetary-to-Case Bearing is a precision-engineered bearing designed to support the interface between the planetary carrier and the transmission case in GM Powerglide transmissions. Machined to fit factory dimensions, this bearing facilitates accurate alignment of the planetary assembly, reducing friction and wear under load. Its durable construction withstands repeated stress cycles and maintains structural integrity during high-performance operation.

Ideal for both high-mileage rebuilds and performance-focused builds, the COA‑12431 bearing restores smooth planetary rotation and contributes to overall transmission durability.
