This is an RC-scale axle spring set designed for TAMIYA CW-01 based models such as the Lunch Box and Midnight Pumpkin. These springs serve as replacement components to restore or modify axle preload and ride height on scale Tamiya models that use the CW-01 axle assembly.
Fit and compatibility: fit these springs wherever the CW-01 axle assemblies specify replaceable springs. They are intended for hobby-grade model maintenance and tuning and are not for use on full-size vehicles.
Installation and tuning role: install the springs into the axle housing following standard axle disassembly and reassembly procedures, verify preload and articulation, then fine-tune ride height and axle response to suit terrain and driving preference. Adjusting spring seating and preload alters weight transfer and low-speed traction behavior.
