KYB Suspension Strut and Coil Spring Assembly P/N:SR4018
KYB SR4521 front left strut assembly for the 2012-2017 Toyota Prius v and other vehicles joins strut, mount and spring in one unit. This complete strut and coil spring assembly handles vehicle weight, sets ride height and acts as the steering pivot.
A worn strut can show up as a bouncy ride, fluid on the strut body or a clunk over bumps. Those signs alone do not prove the strut is the problem, since worn tires can cause an uneven ride too. The front pair is normally replaced together, and this listing is one assembly.
This KYB front strut assembly fits the 2012-2017 Toyota Prius v and the 2011-2016 Scion tC. It is designed for proper ride height and original handling on both.

Is this KYB strut assembly the right one for the 2012-2017 Toyota Prius v?
Yes. KYB SR4521 fits the 2012-2017 Toyota Prius v and the 2011-2016 Scion tC as the front left assembly.
Do KYB complete struts like this one come pre-assembled?
Yes. This front left unit combines the strut, mount and coil spring in one pre-assembled corner assembly.
What spring does the KYB complete strut assembly use?
KYB SR4521 uses a high carbon steel coil spring, application engineered to match the strut and developed from vehicle attributes and corner weights to help restore ride height.
What strut is inside these KYB loaded struts?
This KYB SR4521 unit includes a KYB Excel-G strut with a stronger steel outer shell and application-specific precision designed damping valves.
Can I use this front left strut on the right side?
No. The design and components are side-specific, with separate left and right part numbers, so the front right needs its own assembly.
