Detailed Description

KYB Excel-G shocks are engineered to restore the suspension behavior the vehicle was designed to have, rather than change it. This rear shock absorber uses KYB’s OE-focused Excel-G tuning to support controlled ride quality, stable lane changes, and consistent handling on BMW 530xi Wagon, 535xi, and 535i xDrive models. The compressed length is 12.4 inches, extended length is 16.81 inches, and stroke length is 4.41 inches. Mounting details include lower mount type E2 (15.4 x 66) and upper mount type S1 (12 mm). The 344702 is a direct-fit suspension shock absorber for the rear of these BMW applications.

This part cross-references BMW 33526766585 for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Loose or unstable handling during lane changes
• Reduced tire contact over uneven pavement
• Delayed steering response tied to worn rear damping
• Noise and vibration associated with worn suspension control components

Installation Notes

Compatible with 2006-2007 BMW 530xi, rear; 2008 BMW 535xi, rear; and 2009-2010 BMW 535i xDrive, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5835, to reduce the chance of noise and vibration. Verify mount style and suspension condition before installation.

Quality Assurance

KYB is a major OE shock and strut supplier, and the Excel-G line is built on the same assembly lines used for OE production with OE-quality components. The design includes a triple-lip fluid seal, vehicle-specific damping valves, and a twin-tube gas-charged construction to support consistent suspension performance.
