KYB Suspension Strut Mount P/N:SM5304

$62.99

Description

Cushion harsh road impacts and help quiet the noise and vibration that old, hardened mounts transmit into the cabin with the KYB strut mount SM5304, a direct-fit replacement for the front position on the 1979-1982 Mazda 626 and 1981-1985 Mazda RX-7. KYB engineers this suspension strut mount as an OE-quality component designed for each application, replacing worn vibration insulators that pass jarring and harshness through the suspension.

Superior rubber isolator: cushions impacts from road bumps to help reduce noise, vibration and harshness that worn mounts pass into the vehicle.
Mount bearing: provides smoother steering and helps retain front-end alignment — the front bearing plate acts as the steering pivot and supports vehicle weight, making it critical to steering performance and wheel alignment.
Matched-grade studs and nuts: hardware matched for a secure, correct-fit installation.

If a failed or hardened strut mount is the cause of front-end clunks, added road noise or notchy steering return, this KYB strut mount replaces it. Because the mounts install as a left/right pair, replacing both front sides together is good practice for balanced ride and steering feel.

Frequently Asked Questions

What is the KYB strut mount SM5304?

It is a front suspension strut mount from KYB, an OE-quality replacement that cushions road impacts and, with its bearing plate, serves as the steering pivot while helping support vehicle weight.

What are signs my strut mount may need replacing?

Old, hardened mounts can transmit extra noise, vibration and harshness into the cabin, and a worn front bearing plate may cause clunks or notchy steering return. Diagnose the cause before replacing.

Does this mount help steering and alignment?

Yes. The mount bearing provides smoother steering and helps retain front-end alignment, since the front bearing plate acts as the steering pivot and supports vehicle weight.

Do I need to replace both front mounts?

The front strut mounts install as a left/right pair, so replacing both sides together is good practice for balanced ride quality and consistent steering feel.
