Introducing our ARP 625+ head stud Kit, the ultimate solution for high-powered DAZA engines. Designed to exceed the limits of stock head bolts, our custom kit is engineered to withstand the rigors of high-powered engines, delivering unrivaled strength and reliability.
Key Features:
- Direct Replacement: Seamlessly replaces stock head bolts without the need for block or head modifications, ensuring hassle-free installation.
- Maximum Clamp Load: Featuring a constant diameter shank, our studs deliver maximum clamp load, offering superior stability under extreme conditions. Some other kits use a reduced diameter shank, greatly reducing the holding capability.
- Custom Bull Nose Design: Engineered with a custom bull nose, our studs fully out in the bottom out in the block, ensuring complete thread engagement for maximum clamping force.
- Exceptional Strength: Boasting an impressive tensile strength from 260,000 to 280,000 psi, our ARP 625+ material outperforms any 10mm stud available on the market.
- Tried & Tested: As a shop that builds many DAZA engines, we utilize these head studs in nearly all our full-frame turbo builds.
Crafted from genuine ARP 625+ material, our kit stands apart from generic inconel 625 alternatives, providing uncompromising quality and performance you can trust.
Whether you're running a hybrid turbo setup or a powerful 72mm full frame kit, our custom ARP 625+ head stud kit offers the peace of mind you need for high-performance applications.

Other Availability Modes
We use several availability modes to most accurately identify when products will leave their home facility:
Direct Ship This product is available and will be sourced from one of our suppliers. It may take up to three business days before it ships.

Discontinued - No longer available This product has been discontinued by the manufacturer and is no longer available.
We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
