KYB 3440054 Shock Absorber - Rear

Rear Shock for Durango and Grand Cherokee

KYB Excel-G part number 3440054 is a rear suspension shock absorber for select Dodge Durango and Jeep Grand Cherokee applications. It is built to restore original ride control, steering response, and body stability for drivers who want OE-style performance from a replacement shock.

Excel-G OE Replacement Design

The KYB Excel-G line is KYB’s OE replacement series, built on the same assembly lines used for original equipment production. This nitrogen gas-charged, twin-tube shock uses OE-quality components and vehicle-specific damping calibration to return the suspension to the factory-designed feel rather than changing it. Part number 3440054 is a rear shock absorber for SUVs and crossovers, including Jeep Grand Cherokee and Dodge Durango rear suspension applications.

• KYB recommended OE replacement shock for SUVs and crossovers
• Restores designed control and handling for Jeep Grand Cherokee and Dodge Durango
• 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 minimize flex and maintain alignment
• Electronic safety systems depend on suspension, brakes, and tires working as engineered; this shock helps preserve that balance
• KYB recommends new strut mounts, part number SM5684, to reduce noise and vibration

What This Shock Helps Address

• Excessive rear bounce or float over uneven pavement
• Reduced stability during lane changes and cornering
• Delayed steering response caused by worn rear damping
• Rear-end instability under braking or load transfer
• Noise, vibration, or fluid seepage from an aging shock absorber

Installation Notes and Tips

Confirm rear suspension configuration before ordering, since this shock is not for load leveling, air, electronic, or performance-specific setups listed above. Inspect the upper and lower mounting points, and replace worn mounts if noise or vibration is present. For a complete repair, verify ride height and suspension condition on both sides of the vehicle after installation.
