  • Nitrogen gas-charged, twin-tube construction
  • Triple-lip fluid seal helps reduce oil and gas leakage

Product Details

KYB Excel-G is part of the brand’s OE replacement line, built on the same KYB assembly lines used for original equipment production. Part number 341267 is calibrated to restore factory-designed suspension performance rather than change it, making it a practical choice for drivers who want predictable rear suspension response on Lexus GS300, Lexus GS400, and Lexus GS430 models. This part cross-references Monroe Shocks & Struts (e.g., 71134) for the same application.

Compatible With 1998-2005 Lexus GS300, rear; 1998-2000 Lexus GS400, rear; and 2001-2005 Lexus GS430, rear (except adjustable suspension).

What It Helps Address

  • Excessive rear-end bounce or oscillation
  • Loose or unsettled handling over uneven pavement
  • Reduced steering response during lane changes
  • Uneven tire contact caused by worn suspension damping
  • Suspension performance loss from leaking or fatigued struts

Installation Notes

Fits 1998-2005 Lexus GS300, rear; 1998-2000 Lexus GS400, rear; and 2001-2005 Lexus GS430, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify rear suspension configuration before ordering, especially on GS430 models with adjustable suspension. KYB also recommends a strut boot, part number SB103, to help protect the strut from dirt, debris, and salt.

Quality Assurance

KYB is a global OE supplier, and Excel-G is built as an Original Equipment for the Aftermarket replacement line using OE-quality components and factory-style calibration. Part number 341267 is engineered to restore original suspension behavior on the specified Lexus GS rear applications.
