The One-Way Bearing Mount upgrade provides the ideal solution to the one-way bearing assembly failures common on the market with stock and aftermarket designs. By utilizing a one-piece, high-grade bearing-quality Stainless Steel 440C material construction, precision CNC-machined and secondary hardened to HRC60 rating; the new design provides a robust and failure-free setup for your 700- and 800-class helicopters. No more chance for slipping or failure of the one-way bearing assembly, there are no pressed-in sleeves or bearing-retaining compounds needed. In addition, due to the Stainless Steel construction of the upgrade, the risk of stripping threads for multiple gear chances and maintenance when tightening all hardware is greatly reduced.

Important: The upgrade is a direct bolt-in design for the T-Rex 700/800 series helicopters. To ensure proper operation, please review the Installation Diagram (PDF) for assembly details and tips.
