Head Stud Kit, For Buick '86 - '87

Part Number: 123-4003

Description:

It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there’s not a better stud setup on the market today.

For openers, ARP only uses premium grade 8740 alloy and a proprietary ARP2000® alloy that are rated far superior to “aircraft” quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 200,000 psi for the 8740 material and 220,000 psi for the ARP2000® material. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.

Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs.

ARP studs are thread rolled after heat-treat, which gives them about 2000% (that’s twenty times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.

You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!

Premium quality 8740 and ARP2000® head stud kits are available for most domestic and import applications. You won’t find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality. Clearly, they are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.

International Shipping via GSP (Global Shipping Program)

Buying an item

When shopping, you may notice that some items can be shipped internationally through the Global Shipping Program.

The Global Shipping Program makes it easier for buyers in some countries outside the US to purchase items from US sellers. The seller ships the item to a global shipping provider located in the US and the global shipping provider ships the item to you.

Using a global shipping provider enables sellers to offer international shipping at competitive rates and may allow items to ship more quickly. In addition, your purchase is eligible for coverage through eBay Buyer Protection and PayPal Buyer Protection.

When you purchase an item through the Global Shipping Program, you receive international tracking at no additional charge and pay any applicable import charges upfront. There are no additional charges at delivery. You'll see an estimate of the international shipping charges and any import charges in the item listing. The final charges appear at checkout.

Import charges include certain fees, such as export classification, importation risk premium, and variance fees, which are assessed by the global shipping provider as part of the services provided by the Global Shipping Program. These fees are in addition to the customs duties and taxes imposed by country tax and customs officials. For additional information about applicable fees, see the eBay Global Shipping Program Buyer Terms & Conditions.

Important things to keep in mind:

The charges that you are quoted in the item listing are not final until paid and may change if, for example, you change your shipping address during checkout or if the applicable import rules change before you complete your payment.
With the exception of shipments to Canada, delivery to P.O. Boxes is not supported by the Global Shipping Program. We also can't deliver to APO or FPO addresses.
Checkout

During checkout, you'll see the final charges which include the item cost, the shipping costs (both domestic and international), and any import charges. The shipping costs include any US domestic shipping fees charged by the seller, as well as program fees, international shipping charges, fuel surcharges, and processing and handling fees.

International shipping charges are calculated based on a number of factors including your delivery address, shipping weight, and package dimensions. A network of shipping carriers is used to provide fast and reliable international shipping at competitive rates.

When you pay for the item through PayPal, you are authorizing 2 payment transactions. The first payment goes to the seller and consists of the item cost and the domestic shipping costs. The second payment goes to the global shipping provider and consists of the international shipping costs and any import charges.

After you've completed checkout, you can review these charges on the Order details page. The Order details page shows the total charges and the payment amounts to the seller and global shipping provider.

Note: The Request total from the seller link is not available for Global Shipping Program purchases. You will see the total, including shipping, after you've purchased the item.

Shipping

After receiving your payment, the seller ships your item to a US shipping center. Professional custom processors at the US shipping center process the package, complete customs forms, pays applicable import charges, and ship the package to the address that you specified at the time of purchase. Items that ship through the Global Shipping Program generally arrive within one week after departing the US shipping center.

Tracking

Once the seller has shipped your item, you'll receive an email letting you know that the item has shipped. The email includes a global tracking number which enables you to track your item as it travels from the US shipping center to you. The global tracking number can also be found in My eBay and on the Order details page.
