If the factory lug nuts on your car have started to swell, bulge or seize, this Dorman wheel lug nut, part number 611-084, is a one-piece replacement with an M12-1.50 thread and a dome top, designed to avoid the problems of two-piece factory nuts. It fits many vehicles, among them the 2018-2021 Chevrolet Equinox, 2008-2013 Chevrolet Impala and 2004-2012 Chevrolet Malibu, and is cataloged for both front and rear wheel positions. See the "Vehicles it fits" section for the full list.
On certain vehicles, the original lug nuts use a two-piece design that is prone to failure. A thin outer veneer can be damaged with repeated use. If moisture gets under it, the cover can bulge, which makes the nut hard or impossible to remove, and freeing a stuck nut often damages the wheel. This Dorman OE FIX replacement is built to match the original nut's fit and function. Its one-piece carbon steel construction is designed to prevent the same failures from happening again.
- Improved design: a direct replacement with a one-piece construction, unlike the two-piece factory nut that often fails early.
- Corrosion resistant: there is no veneer, so there is no cover for moisture and rust to bulge and deform.
- Thoroughly tested: put through proof load, salt spray, hardness and thread check testing to meet strict standards.
- Quality engineering: designed in the United States and backed by Dorman's decades of automotive aftermarket experience.
Specifications: M12-1.50 thread, dome top, 19 mm hex, 36 mm length.
