Billet Aluminum Low Servo Cover - Red

BILLET ALUMINUM LOW SERVO COVER (RED, "COAN RACING")

The Coan Racing COA‑12847 Billet Aluminum Low Servo Cover (Red, “COAN RACING”) is a precision-machined, high-performance upgrade designed for GM Powerglide transmissions. Crafted from lightweight aluminum in Coan’s signature red finish, this cover replaces the standard stamped steel version with a more durable, rigid component. It enhances the sealing surface and resists flex and distortion under high line pressure, maintaining hydraulic integrity during aggressive shifting.

The COA‑12847 installs directly into Powerglide servo bores and offers both aesthetic appeal and functional strength. Its robust construction makes it an excellent choice for performance builds, racer maintenance, or any application where reliable shift modulation and long-term durability are desired.
