Rear Differential Isolator – Mopar (5105309AB)

The Mopar Rear Differential Isolator (5105309AB) is a Genuine OEM drivetrain mounting component engineered to reduce vibration and noise transfer between the rear differential assembly and the vehicle frame on compatible Chrysler, Dodge, Jeep, and Ram vehicles. This isolator plays a critical role in absorbing driveline movement and minimizing harshness during acceleration, deceleration, and road impact. Manufactured to strict Mopar factory specifications, it ensures precise fitment and long-term durability.

Constructed from high-density rubber bonded to reinforced steel mounting plates (application dependent), the rear differential isolator is designed to withstand continuous torque loads, drivetrain movement, and environmental exposure. The rubber compound is engineered to provide controlled flexibility while maintaining structural integrity under load. Bonded metal sleeves and brackets ensure secure attachment and proper alignment within the mounting assembly.

The 5105309AB rear differential isolator is developed as a vehicle-specific direct-fit component, matching original mounting dimensions, bolt hole spacing, and durometer (rubber stiffness) specifications. Maintaining OEM dimensional and material accuracy is essential to preserve proper differential alignment and vibration dampening characteristics. Aftermarket isolators that deviate from factory specifications may result in excessive driveline vibration or premature wear.

For professional technicians, installing a Genuine Mopar rear differential isolator ensures compliance with manufacturer drivetrain mounting standards during suspension or differential service procedures. For experienced DIY vehicle owners, selecting the OEM isolator eliminates compatibility uncertainty and restores factory-engineered vibration control without modification.

A properly functioning rear differential isolator supports smooth drivetrain operation, reduced cabin noise, and stable differential alignment. Replacing a worn or cracked isolator promptly helps prevent driveline vibration and protects surrounding mounting components.

• Genuine Mopar OEM rear differential isolator

• High-density rubber bonded to reinforced steel
