KYB 3440018 Shock Absorber - Rear

KYB Excel-G Rear Shock for Ram 2500

The KYB Excel-G 3440018 is a rear suspension shock absorber built to restore original ride control on Ram 2500 trucks. It is an OE-style replacement for 2014-2025 Ram 2500 rear applications without rear air spring and without heavy duty shocks.

Key Features

• KYB recommended OEM replacement shock for rear suspension service
• Restores designed control, handling, lane-change response, and body motion on Ram 2500
• Nitrogen gas-charged twin-tube design for consistent damping performance
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact and steering response
• Strong strut and shock body construction helps minimize flex and maintain alignment
• Dust cover included

Product Details

KYB Excel-G is KYB’s OEA line, built on the same OE assembly lines and with OE-quality components used in original equipment production. Part number 3440018 is calibrated to restore factory-designed suspension behavior rather than change it, making it a practical choice for Ram 2500 rear shock replacement when the goal is to return the truck to its original ride and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 911336) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during braking and lane changes
• Loose or inconsistent rear-end handling
• Uneven tire contact caused by worn damping
• Suspension fluid or gas leakage from an aging shock

Installation Notes

• Fits 2020-2025 Ram 2500, rear, without rear air spring and without heavy duty shocks
• Fits 2014-2019 Ram 2500, rear, recommended OEM replacement; without rear air spring and without heavy duty shocks
• Verify mount type and suspension configuration before installation
• Inspect related suspension components, bushings, and fasteners during replacement
• Confirm the rear shock length and mounting points match the vehicle application before final assembly

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and Excel-G is produced to OE-quality standards on KYB’s OEM assembly lines. The 3440018 is engineered to restore original suspension performance on Ram 2500 rear applications while maintaining the control characteristics expected from factory-style replacement parts.
