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

46mm lightweight swing shafts for TRF421 series

The Tamiya 51760 46mm lightweight swing shafts are direct-fit R/C drivetrain components designed for TRF421X and TRF421 chassis. Supplied as a pair, these swing shafts incorporate ball-bearing joints to reduce rotational friction and help maintain drive speed through steering inputs.

Common uses include replacing worn universal shafts on a TRF421X (Item 42391) or upgrading the stock swing shafts on a TRF421 (Item 42384). When fitted correctly they decrease drag at the universal joints and provide a cleaner transfer of torque through corners, which assists in handling balance adjustments.

Installation notes: confirm shaft orientation and secure retaining hardware to the chassis manufacturer's torque specification, check bearing seating before final assembly, and inspect for play after a short trial run. For routine care, keep bearings free of grit and apply a light lubricant sparingly to avoid attracting debris that increases wear.

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