Each shaft includes sealed CV joints with heavy-duty rubber boots, designed to resist contamination and reduce premature wear so the vehicle regains steady handling and responsiveness.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these CV axles improve driving feel and stability?\u003c\/h3\u003e\n\u003cp\u003eThe axles are designed to transmit constant velocity power efficiently while accommodating steering angles, which reduces vibration and inconsistent torque during turns.
