Keep your rear wheels properly located with the Mevotech Supreme Trailing Arm CMS861177, a direct-fit replacement for the rear left position. It fits many vehicles, among them the 2011-2018 Toyota RAV4, 2018-2021 Lexus NX300 and 2015-2021 Lexus NX300h; see the "Vehicles it fits" section for the full list. This rear suspension link controls fore-aft wheel movement and reacts braking and acceleration loads while helping maintain proper wheel position.
- Stamped steel construction: made to meet OE specifications.
- Corrosion resistance: a protective surface treatment helps resist rust build-up.
- Rear left fitment: a direct-fit replacement for the listed Toyota and Lexus applications.
As part of the rear suspension, this arm works alongside the rest of the linkage. Clunking or knocking from the rear over bumps, rear-end looseness, or uneven rear tire wear can be signs the arm may need replacing — if a worn trailing arm is the cause, this unit replaces the original.
