Bring firm, fade-free damping back to the rear of your van with the KYB Gas-a-just High Pressure Monotube Gas Shock (MPN 5550013), a direct-fit rear shock absorber for the 2015-2024 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD. Offered as an OE monotube replacement, it uses two separate working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

  • High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
  • Up to 25% more damping: adds up to 25% more damping performance over original equipment shocks.
  • Triple chrome-plated piston rod: since fluid leaking can be a cause of shock failure, the ultra-smooth rod is designed to reduce seal wear.
  • Tuned for the Transit: components and valving designed specifically for the Ford Transit, with additional damping for vehicles that work, tow, and run larger, heavier tires & wheels.

The higher gas pressure responds quickly to help improve steering response, and KYB designed the Gas-a-just to help keep Electronic Safety Systems performing as intended. Sold individually — for even, balanced handling, replace both rear shocks as a matched pair.

Frequently Asked Questions

What vehicles does this shock fit?

It is a direct-fit rear shock absorber for the 2015-2024 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD. See the Buyer's Guide tab to confirm your exact configuration.

Is this a front or rear shock?

This is a rear shock absorber. It is sold individually, so order two to replace both rear positions.

How is a monotube gas shock different?

The high-pressure monotube design separates the gas and oil into distinct chambers for fade-free operation and instant response, unlike a twin-tube where they can mix during hard use.

Should I replace both rear shocks at once?

It's recommended. This shock is sold individually, but replacing both rear shocks as a matched pair helps keep damping even and balanced from side to side.

What is the triple chrome-plated piston rod for?

Fluid leaking can be a cause of shock failure. The ultra-smooth triple chrome-plated piston rod is designed to reduce seal wear where the rod passes through the seal.
