Frequently Asked Questions
What vehicle does the SR4513 fit?

What comes in this assembly?
It's a complete corner unit — the KYB Excel-G strut, the upper mount and an application-engineered high-carbon steel coil spring, pre-assembled and ready to install.
Which position is this strut for?
This assembly is built for the rear right corner. KYB uses left and right part numbers with side-specific design and components, so order the correct side.
Do I need to replace both sides?
Replacing struts as a matched pair helps keep ride and handling balanced side to side. This listing is for one rear right assembly; order the opposite side separately if needed.
What signs suggest the strut assembly may need replacing?
Excessive bouncing, uneven ride height, nose dive when braking, or reduced stability and control can indicate worn struts. Diagnose the cause before replacing.
