        What lugnut would I use 1/2 by 20mm??

        • The ARP Rear Wheel Stud - 0.625 in. Knurl retain the use of the stock thread pitch 1/2in x 20.

        Helpful (1)

        are the back side of these where it presses against the backing plate, cut off to allow it to fit past the exciter ring or are they completely round in the back. thank you.

        • The ARP Rear Wheel Stud will require you to press the the ABS Exciter ring off the axle, install the studs, and then press the ring back on, as the studs are completely round on the back.

        Could I put a 2in spacer on these studs

        • You will be able to put spacers on these studs however if your car is track driven, some tracks have a policy against running wheel spacers. Please be advised and contact your local track to see if they will accept spacers with studs like these.

        Would I be able to run a 1" spacer with these an just pull the studs from the spacers ? Would they be long enough?

        • most one inch spacers come with an offset that makes the studs long enough and fit so yes you may.

        What is the spline count on theses studs? Mine is not a Mustang application but a 1984 Toyota 4WD and I'm looking for longer studs for the front as I have switched from steel wheels to aluminum. The truck had wheel spacers on it when I got it and they are of unknown brand/origin. The studs in the spacers have a .62 knurl with 35 splines or "valleys". The strange part is the rear studs are already long enough, only the fronts are too short. I have searched high and low for longer studs to no avail. Thanks

        • Unfortunately for the ARP Rear Wheel Stud - 0.625 in. Knurl I do not have the spline count. It does not appear on the manufacturers website either. I would recommend contacting ARP directly for the spline count.

            I got just what I wanted because of 1/4" spacers. Never will I have to worry about them braking off.

            ARP wheel studs

            ARP is a brand I trust and American muscle had the price I was willing to pay. AM came through again for me with quick shipping and the studs were exactly what I needed to mount my welds. Note to use the studs on the front hubs in 94-98 they will need to be drilled out with a 39/64 drill bit. Perhaps AM could start selling them also. Thanks again guys and gals of American Muscle!!!!

            Brutal

            Great experience with AM. I had sheared the stock driver side lug and bought these to replace all rear studs. About an 1 hour and a half on the install. If you are running stock wheels, you will need open lug nuts. I have a lot more confidence when launching the car now.

            I solid axle swapped my 03 cobra. Needed some longer wheel studs. these pressed into a 98 cobra solid axle no problem. Only pain was getting them passed the tone ring on the axle. I highly recommend these if your looking to upgrade wheels studs.

            wheel studs

            I have used these studs on several AC Cobra replica's due to clearance issues on brakes and wheels. I have had to use some spacers to get the wheel where it needs to be and it is always nice to have some extra treads on your studs to make sure your wheels stay attached during hard driving and racing events.

            Great Product

            Installed these on my 03 Cobra with SRA. Worked out well with my 31 spline axles. They are abit long and some may have to pull the axles to install these. I was able to grind down a small area and work it in. I would recommend going very slow to work these in and be careful with impact gun!
