The Yokomo D-171PA 1.2x10.5 Turn Pink Progressive Spring adds layered spring rates to your RC drift setup, helping you manage transitions and maintain a steady slide. Its 32mm length fits common drift shock assemblies.
By combining tighter coils and wider coils in one spring, the D-171PA soaks up small bumps yet becomes stiffer under heavier load. This creates a smoother initial response and stronger support when the chassis rolls.
The spring pairs effectively with equal pitch units to expand tuning ranges. Mix spring types to tune mid-corner grip, steering onset and throttle response for different drift approaches.
