Our take on the KYB Excel-G 339139 Suspension Strut Assembly

The KYB Excel-G 339139 is a rear-left replacement strut assembly for the 2004 Toyota Avalon. It is a twin-tube gas strut built to restore the original ride rather than stiffen it, and it comes pre-assembled with the mount and spring seat so no spring compressor is needed. It suits owners replacing a worn or leaking factory strut on a stock Avalon. Against performance struts it gives up firmness and cornering bite, but it keeps the soft, quiet ride the Avalon was built for and is a direct fit with no modification.

Pros
  • Direct fit for the 2004 Avalon rear left position

  • Quiet, low-harshness damping for a comfort sedan
  • OEM-style replacement from a major Japanese supplier

  • Ride quality depends on matching the other rear strut
  • Wear items like the mount are not serviceable separately

What reviewers say

Owners of older Avalons and similar Toyota sedans generally report that Excel-G struts bring back a settled, quiet ride close to how the car drove when new. Complaints center on the soft, comfort-oriented damping and on the need to replace both sides at once.

Questions and answers

Does it fit a 2004 Toyota Avalon?
Yes. It is listed for the rear left of the 2004 Avalon. Confirm your model year and rear side before ordering.
Is it a complete assembly or just the strut?
It is a complete assembly with the mount and spring seat, so you do not need to compress the spring.
Should I replace both rear struts at once?
Yes. Replacing one side alone leaves mismatched damping and uneven handling, so plan on the matching right-side unit.
Is this a performance upgrade?
No. It is a stock-replacement strut tuned for comfort. For firmer handling, look at KYB's sportier lines instead.
Does it need an alignment after installation?
An alignment is recommended after strut replacement to reset camber and toe on the rear.
Where is the KYB Excel-G 339139 Suspension Strut Assembly cheapest?
At VEX Motorsports, for $161.63, as of our latest check.
