KYB 3450015 Shock Absorber - Rear

KYB Excel-G Rear Shock for Ram 3500

The KYB Excel-G 3450015 is a rear suspension shock absorber for 2011-2019 Ram 3500 models with dual rear wheels. Built on KYB OE assembly lines and calibrated to restore original ride control, it supports stable braking, lane-change response, and predictable handling on heavy-duty trucks.

Key Features

• KYB recommended OEM replacement shock for the rear suspension
• Restores designed control and handling on Ram 3500 applications
• Nitrogen gas-charged, twin-tube construction
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Strong body and bracket design helps minimize flex and maintain alignment
• Dust cover included

Product Details

Excel-G is KYB’s OEA-style product line for drivers who want original equipment performance characteristics rather than a changed ride feel. Part number 3450015 uses OE-quality components and is built to restore the truck’s original suspension behavior, which is important for electronic safety systems that rely on suspension, brakes, and tires working as engineered. This part cross-references Monroe Shocks & Struts (e.g., 34816) for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced stability during braking or lane changes
• Loose or unsettled handling from worn rear shocks
• Uneven tire contact caused by weak damping control
• Suspension movement that no longer matches factory response
