This slipper spring is designed for the RC10 B74 family of 1/10-scale Team Associated cars. It works with the slipper clutch to provide the tension that controls wheel slip, helping smooth power delivery and protect gears during hard launches and rough traction conditions.

Compatible with the RC10 B74 lineup and its related variants, this spring is a straightforward replacement that supports consistent clutch performance and predictable handling on the track or in practice.
