KYB 341704 Suspension Strut - Rear

KYB Excel-G Rear Strut for BMW 5 Series

The KYB Excel-G 341704 is a rear suspension strut built to restore original ride control, stability, and steering response on select BMW 5 Series models. It is an OE-style replacement for drivers who want factory-correct damping behavior without changing the vehicle’s intended handling balance.

KYB’s Excel-G line is calibrated to return the suspension to designed performance. This rear strut for BMW 528i, 535i, 550i, 525i, 530i, and 545i applications uses a nitrogen gas-charged twin-tube design and OE-quality components assembled on KYB production lines.

Product Details

The KYB Excel-G brand line is focused on restoring original ride characteristics rather than altering them. For BMW 5 Series rear suspension service, part number 341704 is engineered as an OE replacement strut with the dimensions and mounting points needed for the listed applications. It cross-references Monroe Shocks & Struts 72746 for the same application. KYB 341704 is a practical choice when the goal is to return the vehicle to predictable braking stability, lane-change response, and body control.

What This Strut Helps Address

• Excessive rear-end bounce or oscillation
• Reduced stability during braking and lane changes
• Loose or inconsistent rear suspension control
• Uneven tire contact caused by worn damping
• Noise or vibration related to aging strut performance
