TRX-4146 Traxxas Clutch Shoes (2) / Spring (N. Rustler / N. Sport / N. Stampede)

The 4146 is the replacement clutch shoe and spring set for lighter Traxxas nitro vehicles, typically those running the TRX 2.5 engine. The clutch shoes sit beneath the clutch bell and engage it as engine RPM rises, transferring power to the drivetrain. The wrap-around spring holds the shoes retracted at idle and releases them under throttle. These are a wear item — inspect regularly and replace when shoes show glazing, uneven wear, or the spring shows fatigue.
