KYB Suspension Strut Bellows P/N:SB146
Shield your front struts from the grit that wears them out with the KYB Suspension Strut Bellows (Strut Boot Kit) SB174. It installs as a direct-fit replacement for the front position on the 2011-2024 Dodge Durango and 2011-2021 Jeep Grand Cherokee — see the Buyer's Guide tab for engine-level details. By wrapping the polished strut shaft, this kit keeps dirt, dust, sand, salt and road debris from reaching the seal and bushing, the abrasive contaminants that cause premature strut wear.
If a cracked, torn or missing boot has left your strut shaft exposed, this kit restores that protection during your next strut service.
What is included in this KYB SB174 kit?
It includes a durable plastic strut bellows (boot) that covers the shaft plus a poly foam travel-limiting jounce bumper to help protect the strut from bottoming out.
Which vehicles does this fit?
It is a front-position fit for the 2011-2024 Dodge Durango and 2011-2021 Jeep Grand Cherokee. Check the Buyer's Guide tab to confirm your specific vehicle and engine.
What does the strut bellows do?
It wraps the polished strut shaft to keep out dirt, dust, sand, salt and road debris, helping protect the upper seal and bushing from abrasive wear.
What does the poly foam bumper do?
It acts as a travel-limiting bumper designed to help keep the strut from bottoming out and to shield other components from extreme-movement damage.
When should I replace the strut boot?
Signs it may need replacing include a cracked, torn or missing bellows that leaves the shaft exposed. It is a good idea to install a new kit whenever you service the strut.
