The IsoFlex 3/4" T-Bushing Kit TBUSHKIT3/4 is a complete mounting hardware kit designed for IsoFlex flexible coupling systems. This kit includes multiple precision-machined T-bushings used to properly align and secure the coupling between the gearbox output flange and propeller shaft.
T-bushings are critical for ensuring accurate bolt alignment while allowing slight flexibility to absorb drivetrain shock and vibration. This helps reduce stress on the coupling, shaft, and transmission components, improving overall system performance and longevity.
The TBUSHKIT3/4 is specifically designed for 3/4" (19 mm) bolt applications, making it ideal for marine driveline systems requiring imperial hardware or metric-to-imperial conversions.
