Alpha 3-Pc Type Clutch Shoe Spring(soft)-1.0mm

Description

This is a factory-replacement tuning part consisting of soft-rate (1.0mm wire thickness) clutch shoe springs designed for nitro-powered RC engines.

• Function: In a 3-shoe nitro clutch system, these springs hold the clutch shoes back until the engine reaches a specific RPM. Because these are rated as soft, they allow the clutch shoes to expand and engage the clutch bell at lower RPMs compared to medium or hard springs. This delivers smoother, more progressive low-end acceleration, making them ideal for slick, low-traction track conditions where you want to prevent sudden wheel spin.

• Compatibility: This specific spring set is engineered exclusively for the Alpha E59-BU02100 clutch system configuration. It is not intended as a universal fit for other clutch variants.
