Product Details

KYB Excel-G is KYB’s OE replacement line for drivers who need a suspension strut cartridge that matches original equipment performance targets. Built on KYB OE assembly lines with OE-quality components, part number 366006 is calibrated to restore the vehicle’s designed control and handling on the rear suspension. It is a direct-fit solution for 1991 Audi 80 Quattro, 1988-1990 Audi 80 Quattro, 1988-1989 Audi 90 Quattro, and 1984-1987 Audi 4000 Quattro rear applications. This part cross-references Monroe Shocks & Struts 73314 for the same application.

What It Helps Address

  • Excessive rear-end bounce or oscillation
  • Reduced stability during lane changes and cornering
  • Soft or inconsistent damping response
  • Uneven tire contact caused by worn suspension control
  • Noise or leakage associated with aging strut cartridges

Installation Notes and Tips

Fits 1991 Audi 80 Quattro, rear. Fits 1988-1990 Audi 80 Quattro, rear. Fits 1988-1989 Audi 90 Quattro, rear. Fits 1984-1987 Audi 4000 Quattro, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify the upper mount thread specification and confirm all dimensions before installation. For added protection, KYB recommends a strut boot, part number SB105, to help keep dirt, debris, and salt away from the cartridge.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is produced using the same OE assembly processes and quality components used for original equipment applications. The design focus is restoring factory-correct ride control and handling for Audi Quattro rear suspension service.
