KYB 344459 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G 344459 is a rear suspension shock absorber engineered to restore original ride control, stability, and handling. Built for Volkswagen and Audi applications, it is a direct OE-style replacement for drivers who want factory-correct damping response without changing the vehicle’s intended behavior.

KYB’s Excel-G line is calibrated to return the suspension to its designed performance. This rear shock absorber uses OE-quality components and a nitrogen gas-charged, twin-tube design to support consistent control on daily-driven vehicles such as the Volkswagen Passat, Jetta, Golf, GTI, CC, e-Golf, Golf R, R32, and Audi A3.

Key Features

• KYB recommended OEM replacement strut/shock for rear suspension service
• Restores designed control and handling for Volkswagen and Audi rear applications
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Supports proper operation of electronic safety systems by maintaining suspension behavior as engineered
• Heavy-duty strut body and bracket design helps minimize flex and maintain alignment
• Part number 344459 is built as an OE-style replacement in the KYB Excel-G line

Product Line Details

Excel-G is KYB’s original-equipment-for-the-aftermarket line, made on the same assembly lines used for OE supply. The goal is to restore factory ride characteristics rather than alter them, making KYB 344459 a practical choice when rear damping performance has declined on a Volkswagen Passat, Jetta, or Audi A3.

Detailed Description

KYB 344459 is a nitrogen gas-charged, twin-tube rear shock absorber with a compressed length of 14.61 inches, extended length of 23.23 inches, and stroke length of 8.62 inches. It uses an E2(14X37) lower mount and S1 upper mount, with R-stop included and no dust cover, internal rebound spring, or B-stop. This part cross-references Monroe Shocks & Struts (e.g., 5611) for the same application. For fitment-sensitive repairs, verify the rear suspension configuration before installation, especially on Volkswagen models that require replacement of the suspension strut and coil spring assembly according to manufacturer instructions.

What It Helps Address

• Excessive rear bounce or oscillation after bumps
• Reduced stability during lane changes and braking
• Loose or inconsistent rear-end handling
• Uneven tire contact caused by worn damping control
• Noisy or imprecise ride behavior from aging rear suspension components

Installation Notes and Tips

Compatible with rear applications on 2005-2018 Volkswagen Jetta, 2006-2014 Volkswagen GTI, 2006-2010 Volkswagen Passat, 2009-2017 Volkswagen CC, 2010-2014 Volkswagen Golf, 2012-2013 Volkswagen Golf R, 2015 Volkswagen e-Golf, 2008 Volkswagen R32, 2006-2013 Audi A3 without Magnetic Ride Control, and 2022 Volkswagen Passat rear. On many Volkswagen applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5379, to reduce noise and vibration.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced on the same KYB OE assembly lines using OE-quality components. The 344459 is calibrated to restore original suspension performance for rear fitments across Volkswagen and Audi applications.
