Aluminum Rear Support w/ Bearing

ALUMINUM REAR SUPPORT W/BEARING, USE W/ XST OUTPUT SHAFT

The Coan Racing COA‑12849A Aluminum Rear Support with Bearing is a high-performance replacement rear housing designed specifically for GM Powerglide transmissions paired with XST output shafts. Machined from robust alloy and fitted with a durable bearing, this assembly provides precise support and smooth rotation for the output shaft, reducing endplay and significantly improving drivetrain stability.

Unlike standard rear supports with bushings, the COA‑12849A revamps the tailshaft area with enhanced rigidity and longevity, making it a perfect upgrade for competition builds, street/strip applications, or any situation where shaft control and alignment are critical to performance.
