ARP Extended Wheel Studs | M12x1.5 Honda Acura

ARP Wheel Studs M12x1.5 for Honda and Acura

If you've ever snapped a stud torquing down a wheel, sheared one launching at the track, or you're adding spacers and need more thread, this is the fix. ARP wheel studs replace the soft factory studs with heat-treated 8740 chrome moly rated at 190,000 psi tensile strength, the same material ARP uses in its head studs and rod bolts. Stock Honda studs are fine for stock use, but once you're running sticky tires, slicks, wide wheels, or hammering the car at the track, the factory studs become the weak link. These don't.

They come in factory length and extended length, and the extended length is the one most people are actually after. At 2.85 inches it adds a full inch of thread over stock, which is what you want when you're running wheel spacers, thicker aftermarket wheels, or you just want more thread engagement and easier wheel changes in the pits. The factory length is a straight strength upgrade over stock with no change in dimensions, ideal if you're not running spacers and just want studs that won't let go.

Specs

Which pack do you need

Hondas use either four or five lug hubs depending on the chassis, so count your wheel studs per hub and match the pack to it. A 4-lug car needs the 4-pack per corner, a 5-lug car needs the 5-pack per corner. Most people buying for the whole car grab the quantity that covers all four corners. If you're not sure how many your chassis runs, check one hub before ordering.

Available options

Fitment

This is one of the widest-fitting parts in the catalog. The M12 x 1.5 stud fits the vast majority of Honda and Acura platforms from the 80s through today, including the Civic, CRX, Del Sol, Integra, RSX, Accord, Prelude, S2000, Fit, CR-V, Element, NSX, TSX, TL, CL, ILX, and the latest Civic Si and Integra Type S. If your Honda or Acura runs M12 x 1.5 wheel studs (almost all do), these fit. Confirm your thread pitch if you've got an unusual or heavily modified hub.

What to know before you buy

First, these are a press-in stud, not a thread-in, so installing them means pressing the old studs out and the new ones in. It's a straightforward job with a press or even the lug-nut-and-spacer method, but it's not a five-minute swap, budget time per corner. Second, lug nuts are not included, and if you're going extended length, make sure your existing lug nuts have enough thread depth to use the extra length, or grab a set of longer lugs to take advantage of it. Third, the extended length only matters if you need it. If you're not running spacers or thick wheels, the factory length gives you the same ARP strength without sticking out past your lug nuts.
