KYB Coil Spring Insulator P/N:SM5712

$15.99

Description

Cushion the coil spring and quiet the ride with the KYB coil spring insulator SM5712, a front lower spring seat insulator that drops in as a direct-fit replacement for the 2009-2019 Ford F-150, the 2007-2016 Ford Expedition, and the 2007-2014 Lincoln Navigator. It's listed under both names — Coil Spring Insulator / Spring Seat Insulator — so it may show up either way in the catalog. It seats between the coil spring and the suspension, dampening the metal-to-metal contact that old, hardened insulators can no longer absorb.

Restores quiet operation: designed to reduce the squeaks, rattles, and vibration noise that develop as an original insulator ages and hardens.
Application-specific: offered as an OE-quality replacement matched to each listed vehicle for correct spring seating.
KYB quality: built with design and quality that KYB states matches or exceeds Original Equipment.

If a worn or hardened front lower spring insulator is the source of your suspension noise, this replaces it. Diagnose the cause of any clunk or vibration before ordering, since those symptoms can come from other worn suspension components. See the Buyer's Guide tab for the full engine-level fitment for your vehicle.

Frequently Asked Questions

What is the KYB coil spring insulator SM5712?

Which vehicles does the SM5712 fit?

What position is this insulator for?

It is cataloged for the front lower position, seating the lower end of the front coil spring.

Why replace a coil spring insulator?

Over time the insulator hardens and can no longer absorb contact, which may lead to squeaks, rattles, and vibration noise. If a worn insulator is the cause, this replaces it.

KYB states it is built with design and quality that matches or exceeds Original Equipment, offered as an application-specific replacement for the listed vehicles.
