Product Details

KYB Strut-Plus SR4245 combines an OE-restoring KYB strut with a high-carbon steel coil spring selected around vehicle attributes and corner weights to help return ride height to OE specifications. As part of the KYB Strut-Plus line, this assembly is designed for drivers who want a direct replacement for the front right suspension strut and coil spring assembly on a Toyota Prius or Toyota Prius Plug-In without rebuilding the unit separately. This part cross-references Monroe Shocks & Struts (e.g., 172688, 182688) for the same application.

What It Helps Address

• Front-end sag or reduced ride height
• Loose or inconsistent steering feel
• Excessive body motion over bumps and dips
• Worn strut performance that affects handling stability
• Suspension behavior that can interfere with ESC or ABS operation
