TA-01/TA-02 Steel Rear Gearbox Joint HM1041SR Precision Upgrade by GPM  [HM1041SR]

CNC-ready steel rear gearbox joint for M1025 Hummer

This steel rear gear box joint is produced to fit the Tamiya M1025 Hummer rear gearbox arrangement and is listed under model HM1041SR. Supplied as 1 pcs, the component is an aftermarket replacement engineered for improved mechanical resilience when installed in TA-01 and TA-02 style rear housings.

Manufactured with attention to dimensional accuracy, the part offers a metal alternative to plastic joints to reduce deformation under load and improve drivetrain consistency. Install the joint into the rear gearbox using original mounting points and verify shaft endplay and bearing seating during assembly.

For best results check gear mesh, confirm parallel shaft alignment, inspect mating components for wear, and perform controlled bench rotation before track testing. Use recommended fastener torques and follow routine maintenance to preserve performance and fitment.
