What is the KYB gas shock absorber Gas-a-just design?

Does this KYB Gas-a-just shock absorber fit the 2003-2025 Chevrolet Express 2500, 2003-2025 Chevrolet Express 3500 or 2003-2025 GMC Savana 2500?

Is it a front or rear shock?
This is a front position shock absorber for the listed applications.
Do I need to replace both shocks at once?
It is sold individually. Replacing the shocks on the same axle as a pair is recommended for even, balanced ride and handling.

Fluid leaking can be a cause of shock failure. The Gas-a-just uses an ultra-smooth triple chrome-plated piston rod designed to reduce seal wear.
