The CVD bearing drive shafts improve off-power steering and rotation, but decrease straight back traction and security. Ideal for used in high-traction conditions, as well as for tracks with many hairpin corners. Set includes complete drive shaft only. Can be used with #304972 - Gear Diff CVD BB Driveshaft Outdrives. Drive shafts are solely constructed from unique world-renowned, top-secret, self-developed HUDY Spring metal.
