Quick facts
- Part: KYB SR4453 strut assembly
- Also called: complete strut and coil spring assembly
- Fits: 2010-2013 Toyota Highlander and other vehicles
- Position: Front left

A worn strut assembly can show up as a bouncy ride, nose dive when braking or a clunk over bumps. Before you replace it, rule out worn tires, a loose sway bar link or a tired control arm bushing, since those can give similar complaints.
Fits
Use it for strut replacement on the 2010-2013 Toyota Highlander, the 2010-2015 Lexus RX350 or the 2010-2015 Lexus RX450h; it is a direct fit for each. The front axle takes one on each side; this listing is the left, the right is a separate part, and the pair is normally replaced together.

Frequently Asked Questions
Is the KYB complete strut assembly SR4453 the right one for a 2010-2013 Toyota Highlander?
Yes. KYB SR4453 is the front left assembly for the 2010-2013 Toyota Highlander. The front right takes its own part number.
Will the KYB front strut assembly SR4453 fit a 2010-2015 Lexus RX350?
Yes. The 2010-2015 Lexus RX350 is listed for this left-side unit, and so is the 2010-2015 Lexus RX450h.
Does the KYB strut assembly come with the spring and mount?
Yes. KYB SR4453 is a complete corner unit with the strut, mount and coil spring pre-assembled. It is one front left unit, not a pair.
Are KYB complete struts like this one side-specific?
Yes. Left and right units have their own part numbers with side-specific design and components, and SR4453 is the front left.
How can I tell if the front left strut assembly is worn?
With the vehicle parked, look for oil on the strut body or a cracked mount or spring. A bouncy ride or a clunk over bumps are other signs, and a shop can inspect it.
