Fidanza CV Shafts are designed for optimum strength and performance.  Each CV Shaft has a rating of up to 300 HP.  They incorporate outboard cv joints that are 30% stronger than stock joints, as well as a 4340-chromemoly outer joint stub.  The cv shafts' center tube is also 30% thicker than standard tubes, and is manufactured from high-tensile steel.  Thick, rugged boots are loaded with high-tempeture, high pressure synthetic grease to protect and lubricate the CV Joints.  All pertinent shafts include an ABS (anti-lock brake system) ring to ensure the system remains functional on ABS-equiped vehicles
