KYB Suspension Strut and Coil Spring Assembly P/N:SR4642
KYB Suspension Strut and Coil Spring Assembly P/N:SR4642
$263.99

Smooth out a worn front corner and restore factory ride height with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly (MPN SR4642), a complete strut and coil spring assembly that drops in as a direct-fit replacement for the 2007-2009 Lexus ES350 in the front right position. A strut assembly handles vehicle weight, sets ride height, acts as the steering pivot, and helps control vehicle stability. As an original equipment supplier, KYB engineers this pre-assembled corner unit to help bring back your vehicle's original handling and control.

  • OE-restoring design: built on a KYB Excel-G strut with a stronger steel outer shell and application-specific precision-designed damping valves.
  • High-carbon steel coil spring: developed around vehicle attributes and corner weights to help keep ride height within OE specifications.
  • Side-specific build: left and right part numbers carry side-specific design and components, as the vehicle manufacturer intended.
  • Safety-system aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.

Strut, mount, and spring arrive pre-assembled for a professional-grade installation. Worn struts often show up as excessive bounce, nose dive under braking, uneven tire wear, or sagging ride height — if the original strut is the cause, this unit replaces it.
