I have the chrome version ...
*Part # 61108XL
and in the 4+ years of use have not had any issues. BTW ... They're standard on all of the 2004-2008 Saleen F-150s.
Have used Gorilla lug nuts on all of the FoMoCo vehicles that I've purchased since 1999. My other ride (2003 Crown Victoria LX Sport) still has them.
