KYB SB120 Suspension Strut Bellows - Front

KYB Strut Boot Kit for Audi Front Suspension

KYB SB120 is a front suspension strut bellows kit built to shield the strut shaft from road grit and moisture. It is designed for Audi 100, 100 Quattro, A6, and A6 Quattro front applications, helping preserve the polished shaft, upper seal, and bushing.

Key Features

• Superior-quality boot helps protect the strut shaft from dirt and debris that can lead to leaks
• Poly foam bumper helps prevent the strut from bottoming out
• Built to match or exceed OE design and quality
• Helps protect the upper seal and bushing from contamination
• Designed specifically for Audi front suspension applications

Product Details

The KYB Boot Kits line focuses on protecting suspension components from the conditions that shorten service life. On this KYB SB120 kit, the durable plastic bellows covers the strut shaft to block dust, sand, salt, and other road debris before they reach sensitive sealing surfaces. The included travel-limiting bumper adds impact protection during suspension compression. This part cross-references Monroe Shocks & Struts 63973 for the same application.

What It Helps Address

• Strut shaft wear caused by dirt and abrasive debris
• Seal damage that can contribute to fluid leakage
• Bushing wear from contamination exposure
• Bottoming-out impacts during suspension travel
• Damage from extreme movement in front suspension use
