Trade a warped, bulging or hard-to-remove factory lug nut for the Dorman wheel lug nut 611-145, a one-piece carbon steel OE FIX replacement. It fits many vehicles, among them the 1974-1983 Jeep Cherokee, 1987-1991 Chevrolet Blazer and 1975-1991 GMC Jimmy, and serves as a direct-fit replacement for the listed applications. 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 veneer covers the nut and can be damaged with repeated use. If moisture gets underneath it, the cover can bulge, which can make the nut difficult or impossible to remove. A stuck nut often means damaging the wheel to get it off. These Dorman lug nuts are designed to match the original's fit and function while replacing the two-piece construction with a single piece.
- Improved design: A one-piece lug nut replaces the two-piece factory style, which often leads to early wheel nut failure.
- Corrosion resistant: With no veneer layer, there is nothing for moisture and rust to get under and cause bulging or deforming.
- Thoroughly tested: Proof load, salt spray, hardness and thread check testing to meet strict standards.
- Quality engineering: Designed in the United States and backed by decades of automotive aftermarket experience.
Specifications: The Dorman Autograde wheel lug nut has a 7/16-20 thread, a dome top, a 3/4 in. hex and an overall length of 1-19/32 in.
