Strutmasters EZ Strut Toyota Avalon Left Rear vs KYB SR4035 Strut-Plus Assembly

Both are pre-assembled rear strut units that replace the strut, spring and mount in one job. The Strutmasters EZ Strut is the simpler pick: it is sold specifically for the left rear of the 1997-2003 Avalon, and owners report a fast, trouble-free install. The KYB SR4035 is a rear right unit built around a KYB Excel-G strut with a matched high-carbon spring, and it carries the stronger brand reputation for damping quality. Match the side to the corner you are fixing, and replace both sides at once.

• Choose the Strutmasters EZ Strut if you need a left rear unit for a 1997-2003 Avalon and want the easiest bolt-in job with clear instructions.
• Choose the KYB SR4035 if you want a right rear assembly from a major strut maker with application-specific valving and a matched spring.
