KYB 3340199 Suspension Strut - Front Left

KYB Excel-G Front Left Strut for Hyundai and Kia

The KYB Excel-G suspension strut, part number 3340199, is built to restore original ride control, stability, and steering response. It is a direct-fit OE-style replacement for select Hyundai and Kia models, including front left applications on the Azera, Cadenza, Optima, and Sonata.

KYB Excel-G is part of the Excel-G line, a nitrogen gas-charged twin-tube strut series assembled on KYB OE production lines with OE-quality components. For drivers replacing a worn front left strut on a Hyundai Sonata or Kia Optima, 3340199 is calibrated to return the vehicle to its designed damping characteristics rather than alter them.

Key Features

• OE-style replacement strut for Asian vehicles
• Nitrogen gas-charged, twin-tube design
• Vehicle-specific damping valves for controlled tire contact and steering response
• Triple-lip fluid seal helps reduce oil and gas leakage
• Strong strut body and bracket construction to help limit flex and maintain alignment
• Front left application for select Hyundai and Kia models
• Part number 3340199 for easy identification

Detailed Product Overview

KYB Excel-G part number 3340199 is engineered for drivers who want to restore factory ride behavior after strut wear, noise, or handling changes. With a compressed length of 13.66 inches, extended length of 20.63 inches, and stroke length of 6.97 inches, this suspension strut is built around the dimensions needed for the listed front left applications. The 12x1.25 upper mount type and R-stop design are part of the OE-style configuration used to maintain proper suspension operation.

This strut is a strong match for Hyundai Azera, Hyundai Sonata, Kia Cadenza, Kia Optima, and related fitments where original control, braking stability, and lane-change response matter. If you are replacing a worn front left strut on a 2014-2015 Hyundai Sonata or a 2012-2015 Kia Optima, KYB Excel-G 3340199 is designed to restore the vehicle’s original damping feel.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive bouncing after bumps
