KYB Suspension Strut and Coil Spring Assembly P/N:SR4725
Settle the ride and help restore controlled handling on your 2004-2009 Toyota Prius with the KYB Strut-Plus — a rear left Suspension Strut and Coil Spring Assembly (MPN SR4514). This complete corner unit combines the strut, mount and spring in one pre-assembled package, so it drops in without a spring compressor. As an original equipment supplier, KYB engineers the Strut-Plus to help bring the vehicle's handling and control back toward factory feel.
Winner of the 2018 Best Overall Import Aftermarket Product and the #1 recommended OE replacement choice for Asian vehicles. This is a side-specific rear left unit — KYB uses separate left and right part numbers with side-specific design and components; sold individually.

What vehicle does the KYB SR4514 fit?
It's a direct-fit replacement for the 2004-2009 Toyota Prius in the rear left position. Check the Buyer's Guide tab to confirm your exact trim and engine.
Is this a complete strut and coil spring assembly?
Yes. It ships as a complete corner unit with the strut, mount and spring pre-assembled, so no spring compressor is needed for installation.
What is included in the KYB Strut-Plus?
It includes a KYB Excel-G strut with a stronger steel outer shell, application-specific damping valves, a high-carbon steel coil spring and the mount.
Does this one part fit both the left and right sides?
No. This is a side-specific rear left unit. KYB uses separate left and right part numbers with side-specific design and components, as the vehicle manufacturer intended.
Should I replace both rear struts at the same time?
Replacing struts as a matched pair is recommended for balanced handling and even ride height, though this listing is for one assembly and is sold individually.
