Tamiya 51760 46mm Swing Shafts (ball bearing type) for TRF421X and TRF421  [51760]

Precision 46mm swing shafts for TRF421 models

The Tamiya 51760 46mm lightweight swing shafts are manufactured as a direct-fit drivetrain upgrade for TRF421X and TRF421 platforms. Delivered in a pair, each shaft uses ball-bearing joints to minimise rotational friction and help sustain drive momentum during directional changes.

They are commonly used to replace aged universal shafts on a TRF421X (Item 42391) or to upgrade the standard swing shafts on a TRF421 (Item 42384). Proper fitment lowers drag at the joint and smooths torque transfer through turns, which supports fine tuning of handling traits.

Installation guidance: check correct orientation, tighten retaining hardware to the recommended torque for your chassis, verify bearing seating before finalising assembly, and recheck for any play after a brief test run. For maintenance, keep bearings clean and use minimal light lubricant to avoid attracting contaminants.

Recommended complementary parts: when installing on a TRF421 (Item 42384) fit Item 51762 Ball Bearing Set for Universal Shafts and Item 51764 TRF421X Gear Differential Joints (Ball Bearing Type) to ensure bearing and joint compatibility.
