Sintered steel clutch for Zenoah and many other rc-car engines from 23 cm³ to 32 cm³.Note: The sintered steel clutch needs a break in period of at least half an hour run time after their first installation. Only then the clutch surface reaches the desired grip and provides the necessary friction. After that the clutch will show consistent operation and extremely low wear!With 80 grams the weight of the clutch is about the same as the usual OEM clutches.As with all non-adjustable clutches a periodic monitoring of the clutch spring is recommended. By changing the spring, it is also possible to match your car to the track conditions, i.e.: the harder the spring, the higher the stall speed of the clutch.Content:7315 Clutch block carrier7315/01 Screw for carrier7318 Dowel screw for clutch blocksy1419 Sinter clutchy1419/01 Clutch springs for Sinter clutch
