Product Details

KYB Boot Kits are built to keep the exposed strut shaft covered so abrasive contaminants do not reach critical wear surfaces. On Acura MDX rear suspension applications, the bellows helps reduce exposure to harsh road conditions, while the foam bumper adds a layer of protection against bottoming out and extreme movement damage. This KYB SB181 kit is a direct-fit rear strut boot kit for the listed Acura MDX model years.

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

Common Problems Addressed

• Strut shaft wear from road debris
• Seal damage caused by dirt and salt exposure
• Bushing wear from contamination
• Impact damage from suspension bottoming out
• Noise or harshness related to worn bump protection

Installation Notes

Install on the rear strut assembly for the listed Acura MDX applications. Inspect the strut shaft, seal, and surrounding suspension components before installation, and replace worn parts as needed while the assembly is apart.

Quality Assurance

KYB is a suspension-focused brand known for OE-style replacement components. The SB181 boot kit follows that approach by combining shaft protection with a travel bumper in one rear suspension service part.
