Can you reuse ARP 2000 rod bolts?
Yes. As long as the fasteners have been installed and torqued correctly, and show no visible signs of damage, they can be re-used. If they show any signs of thread galling or corrosion, they should be replaced. In the case of rod bolts, if any of them have taken a permanent set and have stretched by .
What’s the difference between Arp 625 and 2000?
The difference between ARP2000 and Custom Aged 625+ starts at the base material. The Custom Aged base material costs more because it is a premium material. The manufacturing process is slightly different, but the main difference is the material itself.
What size are ARP rod bolts?

| Material | 8740 |
|---|---|
| 4) Grip Length | 0.750˝ |
| 5) Head Height | 0.388˝ |

Do you have to resize rods with ARP bolts?
The idea is that if you take a stock rod bolt out, and replace it with one that can clamp down “tighter”, it will distort the rod slightly and then lead to bearing failure. In order to avoid this, resizing of the rod after the ARP bolt install is a good idea.
Are ARP bolts torque to yield?
No, ARP bolts are not torque to yield (TTY). TTY fasteners, when being torqued, actually stretch because of the elastic properties of the material. This gives them the needed clamping force, but the downside it that they aren’t reusable (well, at least they shouldn’t be reused).
Should you use threadlocker on head bolts?
Should I use threadlocker on head studs and bolts? NO. Ok, maybe that was a bit harsh, but you should never use thread locker on head bolts.
What is the tensile strength of ARP 2000?
between 200,000 and 220,000 psi
ARP2000 is tempered above that temperature range and has a strength between 200,000 and 220,000 psi.
How many times can ARP studs be reused?
These studs can be reused after thousands of miles. Unless they yield to wear, you can keep on reusing your studs. Some people have successfully reused ARP head studs more than five times.
What is L19 Steel?
L19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi.
What are the torque specs for ARP head studs?

Are ARP bolts stronger than Grade 8?
ARP’s “Custom 450” alloy has the same tensile strength as the 300 but a higher yield strength. To put all of this into context, your typical grade 5 bolt has a tensile strength of around 120,000 psi, and a grade 8 is in the 150,000 psi range. Both of these yield strengths are far below any ARP fastener.
What is so special about ARP bolts?
ARP’s fasteners are built to withstand serious racing and have higher tensile strengths and can survive higher stresses than most aircraft fasteners will ever see.
What happens if you dont torque head bolts?
Another consequence of failing to torque the head bolts properly can be head warpage. Uneven loading created by unevenly tightened head bolts can distort the head. Over a period of time, this may cause the head to take a permanent set.
What kind of sealant do you use on head bolts?
Loctite Headbolt & Water Jacket Sealant is a single-component anaerobic hybrid that lubricates fasteners during assembly, as well as seals the gaps between the threads. It eliminates corrosion, which can cause difficulties if future disassembly is required.
Do you torque ARP head studs?
NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED. THE FASTENERS, HOWEVER, MUST BE TORQUED PRIOR TO THE LOCTITE SETTING UP. ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil.

Automotive Racing Products
Automotive Racing Products (ARP) started making bolts, nuts, and other fasteners in Southern California 50 years ago. Its start-to-finish handling of every step of manufacturing, from material selection to packaging, has given the company a reputation for quality fasteners that hold up to serious abuse.
