KYB 3440181 Suspension Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G rear shock absorber is built to restore original ride control, stability, stopping response, lane-change handling, and overall suspension performance. This KYB Excel-G, part number 3440181, is a nitrogen gas-charged twin-tube shock made on KYB OE assembly lines with OE-quality components.

For drivers servicing a Toyota Camry, Toyota RAV4, Toyota RAV4 Prime, Toyota Venza, or Lexus ES250, this Excel-G rear shock is an OE-style replacement calibrated to return the vehicle to its designed damping characteristics rather than alter them.

Detailed Description

KYB Excel-G 3440181 is engineered for direct replacement use on rear suspension applications where restoring factory ride behavior matters. It is manufactured on the same KYB OE production lines used for original equipment supply and uses OE-quality components to match the vehicle’s original damping profile. This makes it a practical choice for maintaining predictable control on a Toyota Camry rear shock replacement, as well as rear applications on the Toyota RAV4, Toyota RAV4 Prime, Toyota Venza, and Lexus ES250.

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

What It Helps Address

• Excessive bouncing after bumps
• Reduced rear-end stability during braking
• Loose or unsettled handling in lane changes
• Uneven ride control from worn rear shocks
• Loss of factory-like damping response
