45mm Lightweight Swing Shafts for TRF421 Chassis (TAM42385)

These 45mm lightweight swing shafts are designed for the TRF421 racing chassis and serve as reliable spare parts to keep the setup performing at its best. Also listed as 45mm LW R Swing Shafts, they fit the TRF421 kit and support consistent operation on the track.

A key feature is the 90-degree offset between the drive pin and cross shaft positions, which helps limit vibration while driving. They are compatible with the TRF421 chassis kit, and the lightweight design helps reduce unsprung mass for steadier handling and quicker field maintenance.
