Strutmasters EZ Strut Toyota Avalon Left Rear vs KYB Excel-G 339138 Strut Assembly

Buy the Strutmasters EZ Strut for a 1997-2003 Avalon left rear if you want a bolt-in unit that restores stock ride height with no spring compressor. Buy the KYB Excel-G 339138 only if your car is a 2004 Avalon rear right, since that is the fitment it is built for. The Strutmasters is a complete assembly with spring and mount; the KYB is a bare strut that reuses your existing spring and mount. Owners of the EZ Strut report fast, trouble-free installs, while KYB's Excel-G line is known as a solid OE-replacement damper.

  • Choose the Strutmasters EZ Strut if you drive a 1997-2003 Avalon and want a complete left rear assembly that installs in about an hour without special tools.
  • Choose the KYB Excel-G 339138 if you have a 2004 Avalon and need a rear right strut that reuses your factory spring and mount.

Questions and answers

Which fits my car, the Strutmasters or the KYB?
They fit different cars. The Strutmasters EZ Strut is for the left rear of a 1997-2003 Avalon. The KYB Excel-G 339138 is for the rear right of a 2004 Avalon. Check your model year and corner before ordering.
Is the Strutmasters worth stepping up to over a bare strut?
If you want a fast install and new spring and mount, yes. It replaces the whole corner in about an hour with no spring compressor. A bare strut costs less in parts but takes more labor.
Which lasts longer?
Both are OE-style replacements with similar service life. The Strutmasters also gives you a fresh spring and mount, which removes two other wear items. KYB's damper quality is well proven.
Do I need to replace both sides at once?
Yes, replace struts in pairs on the same axle. A new unit on one side and a worn one on the other can cause uneven handling and tire wear.
Can I install the Strutmasters myself?
Many owners do. It is a direct bolt-in with no modification or special tools, and instructions and videos are included. A basic socket set and jack stands are enough.
