KYB Coil Spring Insulator P/N:SM5468
Cushion the coil spring and hush the suspension with the KYB coil spring insulator SM5632, a direct-fit replacement for the rear lower spring seat. It fits many vehicles, among them the 2003-2017 Honda Accord, 2015-2020 Acura TLX and 2004-2014 Acura TL (see the "Vehicles it fits" section for the full list and engine-level fitment). The insulator seats between the coil spring and its mount, isolating spring movement so it doesn't transmit into the body as noise.
Over time the original insulator hardens and cracks, letting the spring chatter against its seat. This KYB replacement is designed to provide that cushioned interface again.
If a cracked or collapsed spring insulator is the source of your suspension noise, this SM5632 replaces it. Inspect both sides and replace as needed for balanced results.

What position is this insulator for?
This insulator serves the rear lower spring seat on the listed applications.
What are the signs my spring insulator needs replacing?
A hardened or cracked insulator can cause squeaks, rattles and vibration noise as the spring contacts its seat. Diagnose the cause before replacing, since noise can have other sources.
Should I replace both sides at once?
Inspect both rear insulators and replace as needed. Renewing both sides together helps keep the suspension balanced and quiet.
