KYB 3438002 Suspension Shock Absorber - Rear

KYB Excel-G Rear Shock for Fiesta

The KYB Excel-G 3438002 is a rear suspension shock absorber for 2014-2019 Ford Fiesta models. It is built to restore original ride control, stability, braking response, and lane-change handling without changing the vehicle’s designed suspension behavior.

As part of the KYB Excel-G line, this shock is calibrated on KYB OE assembly lines using OE-quality components. For Ford Fiesta rear suspension service, 3438002 is a direct-fit replacement focused on factory-style damping and consistent control.

Key Features

• KYB recommended OEM replacement shock for rear suspension service
• Restores designed control and handling on the Ford Fiesta
• Nitrogen gas-charged, twin-tube construction
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Electronic safety systems depend on suspension, brakes, and tires operating as engineered; this shock supports that factory balance

Product Details

KYB Excel-G shocks and struts are designed to restore original suspension performance rather than alter it. The 3438002 rear shock uses OE-style engineering and damping calibration to help the Ford Fiesta maintain predictable ride quality, braking stability, and road control. This part number is also referenced as Ford D2BZ18125A and D2BZ18125B for the same application.

Fits 2014-2019 Ford Fiesta, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. For related service, KYB recommends new strut mounts SM5802 and a KYB strut boot SB125 to help reduce noise, vibration, and contamination.

What It Helps Address

• Excessive bouncing or poor rebound control
• Loose rear-end feel during braking or cornering
• Reduced tire contact over uneven pavement
• Clunking, vibration, or harsh ride from worn rear shock components
• Loss of factory-style handling response in a Ford Fiesta rear suspension

Installation Notes

Install on the rear position only for 2014-2019 Ford Fiesta applications. Follow manufacturer procedures when replacing the suspension strut and coil spring assembly. Inspect mounts, boots, and surrounding suspension components during service to help ensure proper operation and reduce repeat noise or wear.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is produced on the same KYB OE assembly lines using OE-quality components. The 3438002 is built to restore original designed performance for Ford Fiesta rear suspension service.
