KYB 3358030 Suspension Strut - Front Left

Overview

KYB Excel-G suspension strut 3358030 is built to restore original ride control, stability, and handling response. It is a fitment-based replacement for select BMW X3 and BMW X4 applications, with OE-style calibration that keeps the vehicle’s factory driving character intact.

Key Features

• Nitrogen gas-charged, twin-tube suspension strut design.
• Calibrated to restore original performance rather than alter ride feel.
• Built on KYB OE assembly lines with OE-quality components.
• Internal rebound spring for controlled suspension movement.
• Upper mount type: 12x1.50.

Detailed Description

The KYB Excel-G line is engineered for drivers who want to return suspension performance to factory levels. Part number 3358030 uses the same manufacturing approach and quality component standards found in KYB original equipment production, making it a practical choice for BMW X3 and BMW X4 owners seeking consistent ride control, lane-change response, and handling balance. This part cross-references BMW OE numbers 31316796315 and 31316796409 for the same application.

Fits 2011-2017 BMW X3, front left. Fits 2015-2018 BMW X4, front left. The compressed length is 16.22, extended length is 21.5, and stroke length is 5.28, which are important reference points when matching the correct suspension strut for the vehicle.

Common Repair Uses

• Restoring worn ride control and damping response.
• Addressing excess body movement during braking and cornering.
• Improving stability after suspension wear or fluid loss.
• Correcting reduced steering response and lane-change control.
• Replacing a strut that no longer matches factory ride characteristics.

Installation Notes

Verify fitment by year, make, model, and position before installation. Confirm the upper mount thread specification and overall length measurements against the original part. Professional installation and a post-repair alignment are recommended after strut replacement on BMW X3 and BMW X4 applications.
