KYB 3440020 Shock Absorber - Rear

KYB Excel-G Rear Shock for Ram 2500

The KYB Excel-G 3440020 is a rear suspension shock absorber for Ram 2500 trucks that need restored ride control, stability, and handling. Built on KYB’s OE-focused Excel-G line, it uses vehicle-specific damping to return the suspension to original designed performance.

Key Features

• KYB recommended OEM replacement shock for rear suspension service
• Fits 2020-2025 Ram 2500, rear, w/o rear air springs
• Fits 2014-2019 Ram 2500, rear, w/o rear air spring, w/ heavy duty shocks
• Nitrogen gas-charged twin-tube design for consistent damping response
• 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 strut body and bracket construction helps maintain alignment under load
• Dust cover included; B-stop and R-stop included

Product Details

KYB Excel-G is built on the same OE assembly lines used for original equipment supply and is classified as an Original Equipment for the Aftermarket solution. The 3440020 rear shock is calibrated to restore the Ram 2500’s designed ride control rather than alter it, making it a practical choice for drivers addressing worn suspension performance. This part cross-references Monroe Shocks & Struts (e.g., 68233909AB) for the same application.

Common Issues This Shock Can Address

• Excessive rear bounce after bumps or dips
• Reduced stability during braking, lane changes, or towing
• Loose or unsettled rear-end handling on rough roads
• Uneven tire contact caused by worn damping control
• Suspension noise or fluid leakage from a worn shock absorber

Installation Notes and Tips

Verify rear suspension configuration before installation. This KYB 3440020 is listed for Ram 2500 models without rear air springs, and the 2014-2019 application also requires heavy duty shocks. Inspect mounts, bushings, and surrounding suspension components for wear before replacing the shock absorber. After installation, confirm ride height, fastener torque, and road test the vehicle to verify proper damping response.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is engineered to match original equipment performance targets using OE-quality components. The KYB 3440020 is built for consistent rear suspension control on Ram 2500 applications and is backed by KYB’s OE-focused manufacturing standards.
