RC8B3 FT 4-shoe steel flywheel is a direct replacement for the standard #81370 RC8B3 aluminum 4-shoe flywheel. The steel flywheel is heavier than the aluminum flywheel and increases the overall rotating mass of the clutch assembly. This offers a more stable engine idle and a smoother bottom end throttle feel.

#81370 RC8B3.1 4-shoe Aluminum flywheel = ~12 grams
Fits all RC8B3 and RC8T3 series vehicles and .21 off-road nitro engines.
