KYB 349024 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

KYB Excel-G part number 349024 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for Toyota and Lexus SUV and crossover applications.

The Excel-G line is KYB’s Original Equipment for the Aftermarket offering, focused on returning the vehicle to its designed damping characteristics rather than changing the ride feel. This makes 349024 a practical choice for drivers looking to bring back predictable braking response, lane-change control, and body motion management on the rear suspension.

Key Features

• OE-style replacement shock absorber for Toyota and Lexus SUVs and crossovers
• Nitrogen gas-charged, twin-tube construction
• Vehicle-specific damping calibration to restore original handling balance
• Triple-lip fluid seal helps reduce oil and gas leakage
• Hand-assembled, in-house damping valves manage tire contact, steering response, and body movement
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Dust cover included
• R-stop design included

Detailed Description

KYB 349024 is engineered for rear suspension service on applications such as the 2006-2018 Toyota RAV4, 2015-2020 Lexus NX300h, 2015-2017 Lexus NX200t, 2018-2021 Lexus NX300, and 2021 Lexus NX300h. It is a direct-fit rear shock absorber for vehicles equipped without electronic suspension or electronic adjustable suspension, depending on the application notes. This part cross-references Monroe Shocks & Struts 37289 for the same application.

With a compressed length of 10.78 inches, extended length of 16.33 inches, and stroke length of 5.55 inches, this shock is built to match the suspension travel requirements of the listed vehicles. Upper and lower mount type E2(12.2X45) dimensions support proper fitment when replacing the original rear shock absorber.

What It Helps Address

• Excessive rear-end bounce after bumps
• Reduced stability during braking and lane changes
• Loose or unsettled rear suspension feel
• Uneven tire contact caused by worn damping
• Loss of original ride control on Toyota RAV4 and Lexus NX models
