Mopar Performance 4721434AA Suspension Jounce Bumper

The Mopar Performance 4721434AA is a genuine OEM jounce bumper designed to protect your vehicle's suspension system from excessive wear and impact damage. This critical suspension component acts as a cushion when the suspension reaches its limit of travel during hard impacts, preventing metal-to-metal contact that could lead to costly damage.

Key Features:

• Genuine Mopar OEM part designed to meet factory specifications
• Absorbs shock and dampens noise, vibration, and harshness during impacts
• Prevents suspension bottoming-out over potholes, bumps, and rough terrain
• Protects suspension components including shocks, struts, and control arms
• Manufactured from durable materials for long-lasting performance
• Direct replacement for worn or damaged original bumpers

Also known as a suspension control arm bumper or bump stop, this component is essential for maintaining ride comfort and protecting your vehicle's suspension system. The jounce bumper gradually stiffens the suspension as it approaches full compression, providing progressive resistance that helps absorb sudden impacts from road hazards. Regular inspection and timely replacement of worn jounce bumpers helps prevent premature wear on other suspension components and ensures your vehicle maintains optimal ride quality and handling characteristics.
