        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.

            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

            nhra legal studs

            Pretty easy job. Takes a while and lots a muscle tho lol. If you drag race you NEED these. With slicks stock rear studs are NOT nhra legal with open end lugs( I have 15x10 weld rt-s with ET streets rear) they protrude from the open end lugs nicely,and I see them tearing up lugs before their threads, VERY STRONG. One note: don't use air tools! Use a ratchet a lug you can keep reusing(yes its gonna get messed up) and I used 4 1/2" washers on each stud.just keep tightening till they fit flush.well worth the job ;)

            Easy install

            Had them in in minutes. only problem is that these aren't stock length, but to people like me that's not a problem- that's an upgrade.
