KYB Suspension Strut P/N:341311
KYB 5510022 front left suspension strut for the 2015-2017 Subaru WRX STI controls wheel and spring motion as one of the KYB struts with a monotube gas design. It is an OE monotube replacement meant to restore original capabilities.
Fluid on the strut body, a bouncy ride or a knock over bumps can mean this strut is worn, though a tired strut mount or a worn tire can be behind the same signs, so find the cause before you replace anything.
This front left unit, one of the KYB front struts, is a direct-fit replacement for the 2015-2017 Subaru WRX STI. The listing is one side of the front axle, and the other side is normally done at the same time.

Does the KYB 5510022 strut fit the front left of a 2015-2017 Subaru WRX STI?
Yes. KYB 5510022 is the front left suspension strut for the 2015-2017 Subaru WRX STI; the front right side is a separate part.
Is this one of the KYB shocks and struts with a monotube design?
Yes. This strut is a high-pressure monotube design that separates the gas and oil for fade-free operation and instant response.
Are these KYB gas struts charged with nitrogen?
Yes. The strut has a high-pressure nitrogen gas area with a floating piston, kept apart from its air-free hydraulic piston and valve area.
How can I tell if a front strut is leaking?
Fluid leaking can be a cause of shock failure, so look for an oily film on the strut body with the car parked. This strut's triple chrome plated piston rod is made to reduce seal wear.
Does KYB recommend new strut mounts with the 5510022?
Yes. New strut mounts, part number SM5664, are recommended with KYB 5510022 to reduce the chance of noise and vibration.
