Detailed Product Description

The KYB SB117 is a suspension strut bellows kit that covers the full strut shaft with a durable plastic boot to keep contaminants away from critical wear surfaces. By reducing exposure to road grit and moisture, it helps preserve the polished shaft and sealing areas that are essential to strut performance. The included foam bumper adds travel control during compression events, helping limit harsh bottoming and related suspension damage. This part cross-references Monroe Shocks & Struts 63618 for the same application.

What This Part Helps Address

• Strut shaft wear caused by dirt, dust, sand, and salt
• Seal damage that can lead to fluid leakage
• Bushing wear from abrasive road debris
• Harsh suspension contact from bottoming out
• Damage from extreme suspension movement

Fitment Notes and Installation Tips

• Fits 2004-2010 BMW X3, front; not compatible with vehicles equipped with Sport Suspension.

Verify strut position before installation and inspect the existing strut shaft, seal area, and mounting components for wear. Replace the boot when servicing the strut assembly so the new protection matches the condition of the suspension components being repaired. For BMW X3, Toyota Corolla, and Toyota Celica applications, confirm the vehicle is not equipped with excluded suspension configurations before ordering.
