The Multiquip 21-1600 Square Key 6"x6"x25" is a genuine OEM component designed for TB11E and TB11G power buggies.

DHS Equipment sources this part directly through authorized channels, so you can order with confidence knowing you are getting the correct piece for your TB11 series buggy.
Key Features
- Genuine OEM Material Spec — Manufactured to the original hardness and dimensional tolerances required for positive torque transfer in power buggy drivetrains.
- Drop-In Drivetrain Fit — Sized at 6"x6"x25" to seat correctly in the keyway without filing or shimming, maintaining proper shaft-to-hub engagement.
- TB11 Series Compatibility — Confirmed fitment for TB11E and TB11G Tufftruck power buggies; verify your model code before ordering.
- Maintains Positive Power Transfer — A worn or sheared key allows the shaft and hub to slip under load, robbing the buggy of drive force and accelerating wear on both mating components.
A square key is a precision-machined drivetrain component that locks a rotating shaft to a hub, sprocket, or pulley by fitting into matching keyways cut into both parts. It prevents rotational slipping between the two components, ensuring that engine or motor power is transferred cleanly and consistently to the drive system. When a key shears or wears, the shaft spins freely inside the hub, causing immediate loss of drive and potential secondary damage to the keyway surfaces if the machine is operated further.
