4.0 Good lug nut adapter for fair price

Today I used it for first time and it did what it was supposed to do. Although, sometimes it still scratches paint from my rims. But it's definitely better than the old lug nut adapter that got bent.

Question & Answers

6 Answered questions

Q: Is this a 6 spline? My lugs say Gorilla M14x1.5 HT1 on the bottom. Will this key fit? Answer this question

A: The Small Diameter Spline lug nuts are all a 6 spline pattern. If you have a 14mm x 1.50 thread lug nut, that would be a Duplex lug that uses socket part number 1378SD-KEY.

Q: will this fit my 2007 gmc sierra lug nuts? i think they are 13/16. the aftermarket wheels require a thin walled socket. Answer this question

A: Hello Cody and thank you for your question. Gorilla Automotive Lug Nut Adapter Key works with 1/2" lug nuts. your 2007 GMC Sierra would take 14x1.5 sized lug nuts if it's 1500.
