Product Details
The FCS Shock Absorber Assembly Kit line focuses on suspension replacement parts for common passenger vehicles. This rear shock absorber assembly is listed for the rear position on the Hyundai Sonata, Kia Optima, and Kia Cadenza, with fitment spanning 2015 through 2020 depending on model. The listed dimensions help confirm suspension travel and overall length before installation, which is important when replacing a worn rear shock on a Hyundai Sonata rear suspension or a Kia Optima rear shock application.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number 8346456 should be matched to the vehicle year, make, model, and rear position shown in the fitment data before ordering.
What It Helps Fix
- Rear-end bouncing after bumps or dips
- Excessive body movement over uneven pavement
- Reduced rear suspension control during braking and cornering
- Uneven ride quality caused by a worn rear shock absorber
- Noisy or unstable rear suspension behavior on listed Hyundai and Kia models
Installation Notes and Tips
Verify rear fitment by year, make, model, and position before installation. Confirm the compressed length, extended length, and stroke length against the original part to ensure proper suspension travel. The fitment notes specify a top mount configuration for the listed applications, so compare the mounting style on the vehicle before replacement. For best results, inspect related rear suspension components for wear at the same time.
Quality Assurance
FCS suspension components are cataloged for direct replacement use on the listed applications. Part number 8346456 is specified for rear fitment on 2015-2020 Hyundai Sonata, 2016-2020 Kia Optima, and 2017-2020 Kia Cadenza models.
