KYB 334394 Suspension Strut - Rear Right

KYB Excel-G Rear Right Strut

KYB Excel-G part number 334394 is a suspension strut built to restore original ride control, stability, and steering response. It is a direct OE-style replacement for select Lexus RX330, Lexus RX350, and Toyota Highlander rear right applications.

The Excel-G line is KYB’s OE replacement series, built on the same assembly lines and with OE-quality components used for original equipment supply. This nitrogen gas-charged, twin-tube design is calibrated to return factory-style damping rather than change the vehicle’s handling character.

Key Features

• OE-style replacement for Asian SUVs and crossovers
• Restores designed control, handling, and body motion management
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact and steering response
• Strong strut body and bracket construction helps minimize flex and maintain alignment
• Made in USA
• Part number 334394

Product Details

KYB Excel-G 334394 is engineered for the rear right position and measures 15.4 inches compressed length, 22.81 inches extended length, and 7.41 inches of stroke. It uses an upper mount type of 14X1.50 and includes R-stop construction. For drivers servicing a Lexus RX330, Lexus RX350, or Toyota Highlander, this strut supports factory-style ride control without altering the vehicle’s original suspension behavior. This part cross-references Monroe Shocks & Struts 72215 for the same application.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is built to OE standards on KYB production lines using OE-quality components. Electronic safety systems depend on suspension, brakes, and tires operating as the vehicle manufacturer intended, and this strut helps maintain that original setup.
