        Easy install , no problems

        Twisted the stock studs at Sonoma. Ordered a set of these to replace. Tap your old ones out with a hammer. Pull new ones through with a lug but you don’t mine destroying and some kinda thick washer.

        Perfect fitment

        Fit perfect unlike the .614 moroso studs. No reaming needed. Twice the money but at least it fits.

        Great for drag racing

        I bought these after I snapped 2 studs on both sides one night racing, I've always ran ARP wheel studs on all my mustangs. They are a great product and would suggest that everyone one run them If you make any kind of power.

        Extended studs are a must!!!

        High quality extended studs! They are a perfect fit replacement/upgrade. No need to drill to make them fit like other studs. They are perfect if your running spacers and neet more threads to bolt up to. They peek thru open end lugs and give it a more distinctive look than regular studs. @chukiesthemustangguy

      If I use a 1/2 inch wheel spacer, can i still use my spline lug nuts

      • These studs will require open ended lug nuts which will work with a spacer as well.
