Product Details

KYB Excel-G is the brand’s OE-style product line focused on restoring factory ride performance rather than changing it. This suspension strut is calibrated for the original design intent of the vehicle and uses the same type of quality components found in KYB OEM production. For drivers searching for a Lexus RX350 front left strut, Lexus RX350h front left suspension strut, or Lexus RX450h+ front left OEM replacement, KYB 3350077 provides a direct-fit service part for the listed applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive body movement over bumps and uneven pavement
• Reduced steering response during lane changes
• Front-end instability under braking
• Uneven ride quality from a worn strut assembly
• Loss of factory-like handling feel on the front left corner

Installation Notes

Install on the front left position only for the listed Lexus RX fitments. Verify compressed length, extended length, stroke length, and upper mount thread specification before installation. Inspect related suspension components such as mounts, springs, and bushings during replacement to confirm the repair addresses the full wear condition.

Quality Assurance

KYB is a major OE supplier, and Excel-G is produced on the same KYB assembly lines used for original equipment manufacturing. The OEA classification reflects its OE-style replacement focus for restoring designed performance on compatible Lexus RX applications.
