KYB Strut Boot SB157 for Front Suspension

KYB SB157 strut boot kits protect the exposed strut shaft and seal area from road grit, salt, sand, and dust. For front suspension service on select Toyota Prius and Toyota Prius Prime models, this boot helps keep abrasive debris away from critical strut components.

Key Features

  • Protects the strut shaft, upper seal, and bushing from contamination
  • Durable plastic bellows covers the full exposed shaft area
  • Includes a poly foam travel-limiting bumper
  • Helps reduce damage from bottoming out and extreme suspension movement
  • Fits front suspension applications on select Toyota Prius and Prius Prime vehicles

Product Details

The KYB Strut Boots line is built to shield suspension struts from the debris that accelerates wear over time. On front strut applications, the SB157 forms a protective barrier over the shaft while the integrated foam bumper adds impact protection during suspension compression. This part number, SB157, is listed for 2016-2018 Toyota Prius front and 2017-2018 Toyota Prius Prime front applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Dust and dirt reaching the strut shaft
  • Salt and road debris causing abrasive wear
  • Seal and bushing damage from contamination
  • Bottoming-out impact on the strut assembly
  • Suspension wear on front Toyota Prius and Toyota Prius Prime struts

Installation Notes

Verify front suspension fitment before installation. Replace the boot when servicing the strut assembly or when the original bellows is torn, cracked, or missing. Confirm the vehicle application by year, make, model, and position: Fits 2016-2018 Toyota Prius, front; Fits 2017-2018 Toyota Prius Prime, front. Part number SB157 should be matched to the listed front applications only.

Quality Assurance

KYB supplies suspension components with OE-focused engineering and application-specific fitment. The SB157 strut boot kit is built to support front strut protection on the listed Toyota applications.
