This is a replacement Losi Center/Front CV Driveshaft. This CV Driveshaft is used to connect the center differential to the front pinion gear that drives the front differential, allowing the rotational force from the center differential to transfer to the front differential. CVD driveshafts are different from universal driveshafts in that one driveshaft is made up of three individual components; a driveshaft bone, a coupler, and a coupler joint. The center driveshaft bone is attached to the pinion with the use of the coupler joint, and all components can be replaced making them completely re-buildable.
