Keep road grit off your strut shaft with the KYB Suspension Strut Bellows SB181, a rear strut boot kit that installs as a direct-fit replacement for the 2014-2020 Acura MDX. The durable plastic bellows covers the entire strut shaft, blocking the dirt, dust, sand, salt and road debris that cause abrasive wear to the polished shaft, upper seal and bushing — helping extend the life of the strut.

This kit pairs the boot with a poly foam jounce bumper, so you replace both wear items at once when servicing the rear struts.

  • Durable plastic bellows: wraps the entire strut shaft to keep contaminants out.
  • Poly foam travel-limiting bumper: designed to keep the strut from bottoming out and to protect other components from extreme-movement damage.
  • Seal protection: helps shield the upper seal and bushing from leak-causing dirt and debris.
  • Application-engineered: designed and built specifically for Acura, to a design and quality that matches or exceeds OE.

Fits the rear position on the 2014-2020 Acura MDX; see the Buyer's Guide tab to confirm your vehicle.
