-
Genuine OEM Suspension Component (Hyundai/Kia Mobis Original Equipment)
-
Part Number: 55330-E6100 (Hyundai/Kia OE Number)
-
Component Name: Rear Shock Absorber Upper Mounting Bracket / Bracket-Shock Absorber MTG (Absorber Mounting, Insulator)
-
Primary Applications (Specific): This part number is strongly associated with higher-performance, heavier, or hybrid variants of the platform:
-
Kia Optima / K5 (JF Chassis): Often used for the GT, GT-Line, or high-specification turbocharged models (approx. 2016–2020). The "GT" in your request suggests this performance-tuned mount.
-
Hyundai Sonata (LF Chassis): Often used for the Hybrid models (approx. 2016–2017), where the added weight of the battery pack requires a different damping characteristic.
-
-
Position: Rear Axle, Upper, Universal (This part is symmetrical and used for both the Left and Right sides of the vehicle).
-
Quantity Required: Two (2) per vehicle.
-
-
Key Difference: This mount is a specific variant within the LF/JF platform, differing in its damping or construction rigidity from the standard model part 55330-C1100. It is crucial for maintaining the intended handling and ride quality of performance/hybrid trims.
This is a Genuine OEM Rear Shock Absorber Upper Mounting Bracket, identified by the Hyundai/Kia part number 55330-E6100. This component is a factory-original part designed for the rear suspension of the Kia Optima/K5 (JF chassis) and the Hyundai Sonata (LF chassis), specifically tailored for certain high-specification or specialized models.
While the standard Sonata/Optima often uses part number 55330-C1100, the 55330-E6100 part number is typically designated for models with Electronic Controlled Suspension (ECS), heavier rear loads (Hybrid battery), or a performance-tuned suspension (like the K5 GT). The rubber compound or mounting design provides a slightly different rate of compliance necessary for these specific trims to perform correctly.
The mount's function is critical:
Structural Support: Provides the secure connection point for the top of the rear shock absorber to the body structure.
Performance Damping: The OE rubber compound is specifically calibrated to handle the increased dynamic loads and unique ride characteristics of the GT or Hybrid variants, ensuring the performance suspension operates as intended.
Note on Universality and Compatibility: The part number 55330-E6100 is confirmed to be symmetrical or universal for the rear axle. You need two pieces for a full replacement. If your vehicle is the Optima K5 GT, this specific part number is recommended to maintain the factory performance tune.
Using the Genuine Part (55330-E6100) ensures:
Guaranteed Fitment and Durability: Engineered by Mobis to meet the precise requirements of the performance/hybrid suspension components.
Optimal Handling: Maintains the stiffness and damping characteristics required by the specialized trims.
Compatible Vehicle (Primary Applications - Check VIN for confirmation):
Kia Optima / K5 (JF) (High-spec/GT/Turbo models, approx. 2016–2020)
