What is included in the KYB suspension strut mount kit SM5642?
It supplies the front strut mount along with a boot and bumper, plus matched-grade studs and nuts.
What vehicles does the SM5642 fit?
It's a direct-fit front replacement for the 2008-2014 Lexus IS F, 2006-2013 Lexus IS250 and 2006-2013 Lexus IS350. See the Buyer's Guide tab for engine-level detail.
Which position on the vehicle is this strut mount for?
It fits the front. The front bearing plates serve as the steering pivots and support vehicle weight, so they're critical to steering and wheel alignment.
What are signs my strut mounts may need replacing?
Increased noise, vibration and harshness over bumps, or steering that feels rough, can be signs that old, hardened mounts may need replacing. Diagnose the cause before replacing.
Should I replace both front strut mounts at the same time?
Replacing both front mounts together is recommended so steering feel and ride quality stay balanced and even from side to side.
