Restore the rear-left corner of your Scion tC with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4583, a complete corner unit that arrives pre-assembled with the strut, mount, and spring. It drops in as a direct-fit replacement for the 2005-2010 Scion tC and is engineered specifically for the rear-left position, with side-specific design and components as the vehicle manufacturer intended.
A strut assembly handles vehicle weight, sets ride height, serves as a steering pivot, and helps control stability. KYB starts with an Original Equipment (OE) Restoring strut, then matches it to an application-engineered spring so the assembly is tuned to how the vehicle should ride and handle.
