Are these original GT350 lug nuts - or something else?

[Gary_H]

I recently purchased a 2019 GT350 and trying to figure out if this is an OEM lug nut or do I have replacements?

This is one of the lug nuts:

It is tapered, so a 13/16 does not fully seat:

A 21mm fully seats. This is what I used to remove and re-install it with:

If the 13/16” doesn’t fully seat, someone has already used a 21mm on them, and likely with an impact gun (i.e. they are on their way out, and you should consider swapping them now, before they become a problem).

Those are the standard Ford two piece nuts, at least for a GT (I’m assuming the 350 used the same type)

This might help :



I made that short video following someone on here telling me that couldn’t hold a spanner (or some similar wording), and that 21mm was correct …

Love the video.

I bought a 6 owner 350 with 32k on it. Had to use 3 different socket heads to remove the stock lugs off the car. They are garbage. Replaced them with Optimum Performance lugs.

Thank you for the video link.

Some years ago I had a GLK350 with 2 piece lug bolts. The head looked like a flower, but a metric socket worked on it. The head piece came off one of them revealing a torx head underneath. Fortunately I have a kit with larger size metric E-torx sockets so it was not a big issue.

Buy some sweet Gorilla nuts and call it a day. I love my Gorilla nuts; so hefty.

That is a good plan

Parts for the tone ring TSB are coming in tomorrow and I just removed the decklid panel today to put the Shelby logo back on. Carfax says last oil change was August 2025, so that's coming up on the to-do list.

So for right now, I think the lug nuts are going on the back burner until tire replacement. My plan is to remove the wheels myself and take them to the tire store for mounting. I can then manage not cross threading nor under torquing myself.

What's funny is I sold my '65 convertible (see avitar) in hopes I could cruise this new one a month or two without working on it

Edit: I don't see any concern about driving without a backup camera attached?

Those lug nuts are definitely not one of Fords better ideas. Dump them and get a set of Gorilla nuts. Had my neighbor yesterday that had 2 of them that got stuck in a socket.

I got the Gorilla nuts from CJ Pony, but the seating face looks questionable.

I am hesitant to put 150 fl-lbs of torque on these until I feel confident they will not damage my rims.

Why do you think they would damage your rims ?

I visually noted the Gorilla contact seat is smaller than the OEM. I did not measure the OEM, but this thread indicates it is 30mm. The Gorilla nut is 27mm. I have also contacted CJ Pony, but no response yet.

Are you using the right size lug nuts?? Make sure the outside diameter is right!! | 2015+ S550 Mustang Forum (GT, EcoBoost, GT350, GT500, Bullitt, Mach 1) - Mustang6G.com

Based on my standard Ford nuts and a PP1 wheel :

The standard ford nut measures :

Max OD (over stainless cap) : 30.75mm
Max OD (of the ford taper) : 27.10mm
Max OD (that actually contacts the taper in the wheel) : 25.00mm

I found the last measurement using dry wipe marker on a standard nut and torquing it up.

I can't thank you enough for that feedback/information

I will feel much more comfortable using these!

FWIW I’ve run Gorilla nuts on both S550’s that I’ve owned over the last 6 years. I’ve never had an issue. Each one was/is a daily driver too. You should be good to go

I run these, CJ Pony’s in house brand, same exact design as OEM, just 1 piece so they don’t have the fatal flaw of OEM 2 piece Ford lugs.
