Case Bearing - Requires Machining

CASE BEARING (REQUIRES MACHINING TO CASE)

The Coan Racing COA‑12434 Case Bearing is a precision-engineered thrust bearing crafted for the transmission case of GM Powerglide units. Designed to replace the OEM bearing, it requires machining the case to exact tolerances for a snug and accurate fit.

The COA‑12434 maintains precise alignment and reduces friction between rotating elements. Manufactured to Coan’s high-performance standards, its durable construction enhances drivetrain smoothness, minimizes wear under load, and contributes to long-term transmission reliability in both rebuilds and performance-focused builds.
