Excel-G Product Line Details

KYB Excel-G is the brand’s OEA-style replacement line, focused on returning suspension performance to factory-designed behavior rather than changing ride characteristics. For Audi A4 rear suspension service, part number 349133 is calibrated to match original control characteristics and support the operation of electronic safety systems that rely on proper suspension, brake, and tire performance.

Detailed Description

Compatible with 2009-2012 Audi A4, rear, and 2009-2012 Audi A4 Quattro, rear, KYB 349133 is built for drivers replacing worn rear shocks on vehicles with standard suspension. The compressed length is 16.33 inches, extended length is 26.18 inches, and stroke length is 9.85 inches. Mounting configuration includes lower mount type E2(14X37) and upper mount type S1.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during braking and lane changes
