HPI Racing 113578 Clutch Spring Set (0.8mm, 0.9mm, 1.0mm)

This is a genuine HPI Racing clutch spring set including 0.8mm, 0.9mm, and 1.0mm springs. Clutch spring thickness controls engagement RPM, so this three-spring assortment lets you tune how your clutch bites — from smoother early engagement to a harder, later hit.

Springs fatigue with use, and fresh factory springs restore consistent engagement. A great tuning and maintenance pack for any nitro or gas clutch.
