KYB 5550006 rear shock absorber for the 2014-2026 Ram 3500 damps rear suspension movement with a high-pressure nitrogen gas chamber. This KYB shock absorber is a Gas-a-Just monotube that adjusts automatically to your performance needs.
- KYB Gas-a-Just monotube design with a floating piston that separates the gas and oil for fade-free operation
- Air-free hydraulic piston and valve area for responsiveness and control
- Triple chrome plated piston rod to reduce seal wear
- Higher gas pressure for quick response and improved steering response
- Additional damping for vehicles that work, tow and run larger, heavier tires and wheels
Quick facts
- Part: KYB 5550006 shock absorber
- Also called: suspension shock absorber
- Fits: 2014-2026 Ram 3500
- Position: Rear
- Condition: New
Fluid leaking from the body, a bouncy ride or a clunk over bumps can mean a shock is worn. Before you replace one, rule out the tires, worn bushings or mounts and other suspension parts that can cause a similar ride complaint.
Fits
This shock absorber fits the 2014-2026 Ram 3500. Its components and valving are designed specifically for Ram 3500s, and the damping adds up to 25% more damping performance than original equipment shocks. The other side of the rear axle is normally replaced at the same time.

Frequently Asked Questions
Is this KYB rear shock absorber right for the 2014-2026 Ram 3500?
Yes. KYB 5550006 is a rear shock absorber for the 2014-2026 Ram 3500, and the truck takes two on the rear axle.
How does the KYB Gas-a-Just shock absorber differ from a twin-tube design?
It has two separate working chambers: an air-free hydraulic piston and valve area, and a high-pressure nitrogen gas area with a floating piston. It never experiences fade due to aeration.
Is this KYB gas shock absorber filled with oil or gas?
Both. The high-pressure monotube design keeps the oil and the nitrogen gas apart, which gives fade-free operation and instant response.
Does fluid on a suspension shock absorber mean it has failed?
Fluid leaking can be a cause of shock failure. The triple chrome plated piston rod on KYB 5550006 is made to reduce seal wear.
Does this shock absorber add damping for towing and heavier tires?
Yes. The Gas-a-Just monotube adds damping over OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
