Toyota Avalon Rear Strut & Sway Bar Kit vs KYB SR4035 Strut-Plus Assembly

For a 1997-2003 Avalon rear refresh, the four-piece kit is the practical buy: it covers both rear corners and the sway bar end links in one order, and the lifetime warranty backs it. The KYB SR4035 is the better-engineered single corner, with an Excel-G twin-tube strut, a matched high-carbon spring and side-specific valving, but it is one assembly, so a full rear job needs a second part number. Owners and reviewers rate KYB's damping and fit highly; the kit wins on completeness, KYB on refinement and brand track record.

• Choose the four-piece kit if you want both rear corners plus new sway bar end links in one box, with a lifetime warranty and no spring compressor needed.
• Choose the KYB SR4035 if you are replacing one rear corner and want OE-style damping, a matched spring and side-specific construction from a known suspension brand.
