Product Details

KYB SB139 is a suspension strut bellows designed to cover the full strut shaft with a durable plastic boot, helping keep out dust, sand, salt, and other road debris. By reducing exposure to abrasive contaminants, this front strut boot kit supports longer strut service life and helps maintain the condition of the polished shaft, upper seal, and bushing. The KYB Boot Kits product line is focused on OE-style protection for suspension components in demanding truck and SUV use.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
