Unique Multi-Adjustable Slipper Clutch - MSC, with independently adjustable FRONT and/or REAR slippage via different slipper pads and clutch plates of different diameter, ensures more efficient and more consistent clutch operation to generate faster acceleration and less wheel spin. For improved performance there are two different pads with different hardness, yellow SLS pads with higher slippage and black medium hardness with less slippage. The slippage ratio between front and rear tires can be adjusted independently depending on the type of the track, tires and racing style. The Multi-Adjustable Slipper Clutch is included in Carpet Edition. Fits XB4\'20-21, XT4\'20
