These new "Stiletto" Spikes are 4 1/2" long and have a 1/2" neck. The normal style spike is 4" long with an 1 1/2" of neck. Therefore with these you actually get more spike and less cylinder.
the whole reason i wanted a dually to start with was so that i could run spike lug covers...now i cant cause my truck tucks half the wheel and there to long
