Beck/Arnley Suspension Stabilizer Bar Link P/N:101-7943
Reconnect the rear stabilizer bar to the suspension with the Beck/Arnley sway bar link (P/N 101-8838, also written 1018838), a direct replacement built for the 2020-2024 Subaru Legacy. This rear link ties the stabilizer bar to the suspension so the bar can resist body roll as the vehicle corners; when the link's joints wear, you may hear clunking or rattling over bumps or feel looser handling — signs this part may need replacing. Because it's application specific for this vehicle, it drops in like the original.
Stabilizer bar links wear on both sides at similar rates, so inspect the opposite-side link and consider replacing them together for balanced rear handling. See the Buyer's Guide tab for engine-level fitment details for your Legacy.

What is a stabilizer bar link?
Also called a sway bar link, it connects the rear stabilizer bar to the suspension so the bar can resist body roll while cornering. Worn links can rattle, clunk, or reduce handling response.
Does the Beck/Arnley 101-8838 fit my vehicle?
It is an application-specific replacement for the 2020-2024 Subaru Legacy. Check the Buyer's Guide tab to confirm the exact fit for your vehicle and engine.
Is this a front or rear link?
This is the rear stabilizer bar link. It mounts at the rear of the vehicle, connecting the rear stabilizer bar to the suspension.
Does it come with mounting hardware?
Yes. Per the manufacturer, it comes with the necessary components and hardware for a complete installation, and the hardware functionality matches the original design requirements.
Should I replace both links at once?
It's a good practice. Links on the same axle wear at similar rates, so inspecting and replacing the opposite-side link at the same time helps keep rear handling balanced.
