Outback owners, we hear you, the stock 16-18mm rear sway bar is just not enough. Upgrade to the 2015-2021 STI 20mm bar for a massive increase in rear roll stiffness, or a slightly milder 19mm bar if you want a little more rear suspension articulation.
(Why does the thinner bar cost more than the thicker one? It is another Subaru parts pricing mystery.)
Kit includes an OEM Subaru rear sway bar plus a pair of the appropriate-sized sway bar bushings.
Fits all 2015-2018 Subaru Legacy and Outback.
