  • Features:
    • Improved design - direct replacement, one-piece lug nut design, vs. two-piece factory design that often leads to premature failure of the wheel nut
    • Corrosion resistant - by removing the veneer of the OEM lug nut design there's no chance of moisture and rust causing it to bulge and deform
    • Thoroughly tested - part has undergone 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
  • The original lug nuts on certain vehicles have a failure-prone two-piece design that makes warping common and removal difficult. There's often a thin veneer that gets damaged with repeated use, and if moisture gets underneath it can cause the cover to bulge. Those failures can make the nuts difficult or impossible to remove, and if they get stuck, removing them usually requires damaging the wheel itself. This Dorman OE FIX replacement matches the OE fit and function but has a one-piece, carbon steel design to prevent similar issues from happening in the future.
