What vehicles does the KYB 5550010 shock absorber fit?
It's a direct-fit rear replacement for the 2015-2023 Ford Mustang. Check the "Vehicles it fits" section for engine-level applications for your specific vehicle.
Is this a front or rear shock?
This KYB Gas-a-just is a rear shock absorber and installs in the rear position on the listed applications.
What makes the Gas-a-just a monotube design?
It uses a high-pressure monotube layout that separates the gas and oil into two chambers for fade-free operation, quick response, and control.
Why does it have a triple chrome-plated piston rod?
Because fluid leaking can cause shock failure, the ultra-smooth triple chrome-plated rod is designed to reduce seal wear.
Are these shock absorbers sold in pairs?
This listing is for one shock absorber. For even, balanced handling, it's best to replace both rear shocks as a matched pair.
