Do I need to replace struts in pairs?

Yes, struts should always be replaced in pairs (both front or both rear) to maintain balanced handling and ride quality. Compatible vehicles include 1993-2008 Lexus SC430, GS300, GS430 and more. Uneven strut wear causes pulling, uneven tire wear, and compromised safety.

Is wheel alignment required after strut replacement?

What does a strut mount do?

It connects the strut assembly to the vehicle body, allows the strut to pivot during steering, and isolates road vibration from the cabin using a rubber bushing and bearing plate.
