Now you can upgrade your SC10 4×4 short-course truck to the latest competition spec. This new kit allows the use of a saddle-pack battery to optimize the weight distribution of the chassis. With the addition of the Factory Team carbon-fiber chassis brace rod, the chassis flex has been made more consistent and predictable for an overall improvement in handling and traction. One of the more radical features on the SC10 4×4 Factory Team kit is now available to you, the VTS4 slipper clutch, a variable torque, multi-plate slipper clutch with four drive surfaces. The VTS4 slipper clutch provides increased torque capacity in addition to finer resolution adjustments. It all adds up to more consistent power transfer to the ground.
