These will solve the many issues associated with the stock center driveline. First off it’s FAT! Yet it’s still extremely lightweight. It’s a dog bone rather than a simple splined shaft and as such will not bind, split, or bend the way the stock shaft does. The laser etched shaft is machined from high quality aluminum and anodized for incredible wear. Newly designed hardened steel outdrives on either end replace the weaker stock parts for the ultimate center driveline available for the Slash 4x4 vehicles. So yeah, it’s a ‘must have’ for any racer or basher. Another rock solid upgrade from Tekno RC! Features  FAT, Big Bone shaft is much stronger than stock  Dog bone design will not bind, split, or bend like the stock unit  Lightweight aluminum shaft, hardened steel outdrives  Laser etched and black anodized for wear * The O-rings go inside the drive cups, two in each cup.
