Excel-G Product Line Details

KYB Excel-G is the brand’s OE-style replacement line for drivers who want suspension performance that follows the vehicle’s original tuning. The design uses the same type of quality control and component standards found in KYB OEM production, with damping calibrated to manage tire contact, body motion, and steering response without changing the vehicle’s intended character. The KYB 344663 follows that approach for rear suspension service on select Hyundai and Kia applications.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced lane-change responsiveness
• Loose or unstable rear-end feel
• Uneven tire contact from worn damping
• Suspension noise or fluid leakage from a worn shock absorber

Installation Notes

Fits 2013-2018 Hyundai Santa Fe, rear; 2013-2018 Hyundai Santa Fe Sport, rear; and 2014-2015 Kia Sorento, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style and dimensions before installation. This part cross-references Monroe Shocks & Struts (e.g., 37377) for the same application.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is built on KYB OE assembly lines using OE-quality components. The design focus is restoring factory ride control and maintaining proper suspension behavior for vehicles with electronic safety systems that depend on suspension, brakes, and tires working as engineered.
