KYB Suspension Strut and Coil Spring Assembly P/N:SR4027
KYB SR4643 front left strut assembly for the 2007-2009 Lexus ES350 handles vehicle weight and sets ride height at that wheel. This KYB strut assembly, also called a complete strut and coil spring assembly, also acts as the steering pivot and helps control vehicle stability.
A knock over bumps, oily residue on the strut body or a leaning front end can mean a worn strut. A worn top mount can look similar, so look over the strut, spring and mount with the engine off before replacing anything. This listing is one assembly for the front left; the right is a separate part, and both sides are normally replaced together.
This KYB front strut assembly fits the 2007-2009 Lexus ES350, which takes one on the front left.
Fit and size
Build and materials
One front left strut assembly with its coil spring.
Does the KYB SR4643 fit the left side of a 2007-2009 Lexus ES350?
Yes. KYB SR4643 is the front left strut assembly for the 2007-2009 Lexus ES350. The front right side uses its own part number.
Do KYB complete struts like the SR4643 come with the coil spring?
Yes. KYB SR4643 comes pre-assembled with the KYB Excel-G strut and an application-engineered KYB coil spring, so the spring is not a separate order.
What is the spring made of on this KYB complete strut assembly?
The coil spring is high carbon steel. It is developed from vehicle attributes and corner weights to help restore ride height within OE specifications.
How can I tell if my front left strut is worn?
Oily residue on the strut body, a knock over bumps or a front end that leans can be signs of wear. A shop can also test the strut for you.
Are KYB loaded struts side-specific?
Yes. Left and right have their own part numbers with side-specific components. KYB SR4643 is the front left.
