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

46mm swing shafts: specification and fitment

The Tamiya 51760 46mm lightweight swing shafts are direct-fit R/C drivetrain components intended for TRF421X and TRF421 platforms. Provided as a pair, these shafts use ball bearings at the joint to cut rotational friction and help preserve drive speed when the car changes direction.

They are suitable for replacing worn universal shafts on a TRF421X (Item 42391) or upgrading the standard swing shafts on a TRF421 (Item 42384). Correct installation reduces drag at the universal joints and produces a tidier transfer of torque during cornering, which can assist in fine tuning handling balance.

Installation notes: check orientation, secure the retaining hardware to the recommended torque figure for your chassis, confirm bearing seating before final assembly, and inspect for play after an initial run. For maintenance, keep bearings clean and use a light lubricant sparingly to avoid attracting abrasive debris.

Recommended complementary parts: when fitting these shafts to a TRF421 (Item 42384) use Item 51762 Ball Bearing Set for Universal Shafts and Item 51764 TRF421X Gear Differential Joints (Ball Bearing Type) to guarantee bearing compatibility and consistent drivetrain behavior.
