KYB Suspension Strut Bellows P/N:SB172
Fight off leak-causing grit with the KYB strut bellows SB151, a front strut boot kit that shields the polished shaft, upper seal and bushing from the dirt, dust, sand, salt and road debris that cause abrasive wear. It's a direct-fit boot kit for the front struts of the 2016-2022 Lexus RX350, 2016-2022 Lexus RX450H and 2017-2019 Toyota Highlander — see the Buyer's Guide tab to confirm your vehicle.
If a torn or missing boot has left your original strut shaft exposed, this kit restores that protective barrier during a strut service.
What does the KYB strut bellows SB151 do?
It covers the entire front strut shaft with a durable plastic bellows, keeping dirt, dust, sand, salt and road debris off the polished shaft, upper seal and bushing.
Does the SB151 fit my vehicle?
It's a front application for the 2016-2022 Lexus RX350, 2016-2022 Lexus RX450H and 2017-2019 Toyota Highlander. Check the Buyer's Guide tab to confirm your exact vehicle.
Does this kit include a bumper?
Yes. It includes a poly foam travel-limiting bumper (jounce bumper) designed to keep the strut from bottoming out and to limit extreme-movement damage to other components.
Why should I replace a torn strut boot?
A torn or missing boot exposes the shaft, letting abrasive contaminants reach the shaft, upper seal and bushing, which can lead to leaks and shorten strut life.
Is this a front or rear part?
The SB151 is a front strut boot kit for the listed Lexus and Toyota applications.
