From Factory Team:
Factory Team is excited to announce the Lightweight Center Driveline kit for the RC10B74 series of vehicles. This driveline kit reduces the rotational mass of the center driveline by a total of 19.3g over the standard steel parts! Durability and longevity were addressed with the use of plastic blades that act as the contact surface between the dog bone pins and outdrives to reduce wear and tear.
This kit is intended for use in the 13.5T Spec class with the combination of a center differential and is not recommended for modified racing or with the use of a slipper clutch.
Fits the RC10B74, RC10B74.1, RC10B74.1D, RC10B74.2, RC10B74.2D
