TAMIYA TRF 416 Differential Screw Set 416-10B by 3Racing  [416-10B]

Replacement screws overview

The 3Racing 416-10B screw set is supplied as a direct replacement for the TAMIYA TRF 416 differential assembly and is intended for routine maintenance and rebuilds to restore reliable fastening inside the diff housing.

This kit suits hobbyists servicing their TRF 416 diffs: it replaces worn or damaged fasteners that secure differential components, helps keep alignment during reassembly, and aids consistent preload when fine tuning the unit. The focus here is on fitment and compatibility rather than performance claims.

Installation notes: follow the TRF 416 service procedure to disassemble the diff, move internals as required, and install the replacement screws evenly to avoid skewed assembly. Verify that rotating parts spin freely after reassembly and use correct small-scale tightening practice to prevent thread damage.

Tuning context: when changing oils or shims on a TRF 416 differential, fresh hardware promotes repeatable assembly and even torque transfer across the diff case, which helps achieve predictable differential action.
