This part cross-references / interchanges with the following part numbers:
Where does this shock mount?
The KYB Gas-a-just KG5498 is a rear-position shock absorber for the listed Ford E-Series vans. Check the Buyer's Guide tab to confirm fitment for your vehicle.
What is a monotube gas shock?
It's a high-pressure design that separates the gas and oil in a single tube, using a nitrogen chamber and a floating piston for fade-free operation and instant response.
How does it compare to original-equipment shocks?
KYB states the Gas-a-just adds up to 25% more damping performance over OE shocks, with components and valving designed specifically for Ford vans.
Should I replace shocks in pairs?
This listing is for one shock. Replacing both rear shocks together is recommended so damping stays balanced side to side.
What are signs a shock may need replacing?
Excessive bouncing, bottoming out, poor control over bumps, or fluid leaking from the shock body are common signs a worn shock may need replacement.
