Frequently Asked Questions
What is the KYB SM5585?
It's a KYB rear upper strut mount — a mount plate with insulator that isolates the top of the rear strut and replaces old, hardened insulators to reduce noise and vibration.

What are signs my strut mount may need replacing?
Clunking or knocking over bumps, added vibration, and noise transmitted into the cabin can indicate a hardened or deteriorated mount. Diagnose the cause before replacing, as other parts can produce similar symptoms.
Does the SM5585 include mounting hardware?
KYB lists matched-grade studs and nuts among this mount's features. Consult the vehicle service information for the correct torque and any single-use fasteners.
Should I replace both rear mounts at once?
It isn't required, but replacing the rear upper mounts on both sides together is good practice for balanced ride quality and even wear.
