The Tekno RC HD Hardened Steel Differential Coupler is a heavy-duty drivetrain component designed for compatible Tekno RC vehicles. Manufactured from hardened steel, the TKR5075HD provides a strong and durable connection between the differential and center drivetrain while maintaining factory fit and geometry.
This coupler is included as standard equipment on select Tekno RC platforms and can be used as a direct replacement when servicing the original drivetrain. Its heavy-duty construction also makes it suitable for demanding racing and high-power applications.
The TKR5075HD is manufactured from hardened steel to provide the strength and wear resistance needed in high-load drivetrain applications.
The HD design provides a durable solution for transferring power through the drivetrain while standing up to repeated acceleration, braking, jumping, and demanding track conditions.
This differential coupler is included from the factory with the SCT410 2.0, MT410 2.0, and MT48 2.0, making it a genuine replacement component for these vehicles.
Using the original Tekno RC component helps maintain proper drivetrain geometry and factory-designed fitment when replacing a worn or damaged coupler.
TKR5075HD can also be used with compatible Tekno RC center dog bone driveshaft configurations. Tekno specifies TKR5075 or TKR5075HD as the required differential coupler when installing its newer steel center dog bones, including TKR9376 and TKR9377.
This gives the coupler additional usefulness when configuring compatible vehicles with alternative center drivetrain setups.
