What can I use instead of ARP Lube?

Can I use Loctite or any thread locker instead of ARP Ultra-Torque assembly lube? Yes, you can. Some engine builders use blue Loctite on the stud end that goes into the block. Do NOT use Loctite on the nuts for the head studs or main studs.

How many times can you torque ARP head studs?

Generally bolts/studs that have a specific torque value to tighten to are reuseable, but bolts that you torque then turn an extra 1/4 turn or a number of degrees are torque to yield bolts and shouldn’t be reused more than once.

Do you lube head bolts?

Motor oil will be fine. It’s cheap, plentiful and what Honda recommends using. Head bolts are usually torque to yield and usually require replacement after use.

Why are ARP bolts so expensive?

ARP stuff is typically more expensive than other brands, but again, that’s because they use more expensive materials, and the manufacturing process, from heat treating to machining, is more involved.

Can you reuse ARP head studs Cummins?

Yes, you can reuse them. No need to send them in.

Can you reuse Arp 425 head studs?

Are ARP bolts stronger than Grade 8?

ARP “Stainless 300” is specially alloyed for durability, and the tensile strength is typically rated at 170,000 to 190,000 psi. 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.

Can Arp 425 be reused?

What is the ARP Ultra-Torque Lube?

With the extremely precise testing equipment, they set out to develop a lubricant to help reach preload easier and more consistently than not using anything or using other lubricants that are currently on the market. ARP tested their ARP Ultra-Torque, Oil, Moly and EPL (extreme pressure lube).

What is the best Lube for diesel engines?

Now, just try to tell us that wouldn’t be a major contributing factor to a failure. With diesel torque ratings being as high as they are; ARP, also, tested the most common lubes used in diesel shops. Those were oil, Moly, Detroit Diesel #2 (Peanut Butter) and ARP Ultra-Torque. The first round of testing was done at 210 ft-lbs.

Does the Assembly lubricant affect the reliability of your engine?

The moral of the story is that the assembly lubricant that you opt for can make a substantial impact in the reliability of your engine. Engine manufacturers specify a specific torque rating on bolts because they anticipate a certain preload on those bolts.
