ARP Ultra Torque for head bolts and other fasteners

I saw a demonstration of this stuff on Horsepower TV today and looked up the website. It looks like it is far superior to motor oil for lubricating the threads on a fastener to ensure accurate torque readings.

If you are going to have your engine apart for any reason, I would get some of this.

Are you talking about head studs or the thread lubricant?
This thread is about the lubricant.

Both it's a must I have never replaced a cylinder with out doing this procedure above this includes new bolts. Done my share of having engines built and ARP heads studs are in the rzr,raptor to the 6.0 ford. When I was building thr rzr I was amazed there was no ARP heads for the rzr. Come to find out me and another guy on this form where in contact with arp to get some sized up to fit the same week, worked out great.

If you listen to the guy talk the bolts/studs take a beaten just removing them. It's just save practice on a high hp. application
So how much do the ARP head bolts for a RZR cost? I know they run about 550 bux for my 6.0 powerstroke depending on where you buy them.
Jeff --

I recommend one not use bolts to secure the head/cylinder to the case.

Use studs instead.

As to where to source and the part number -- Read this post .. I don't know who he is -- Butt looks like he did a damn fine job ............

To answer the question at the end of the story - Yes .. One does have to machine off the Bull Nose. Chopsaw or hand grinder also works.

That doesn't cause you to need to remove the motor to pull the head and cylinder does it? Looks like it would be close to hitting the frame when removing them, maybe not I didn't measure it just ran out and took a look.
Can you double nut the studs for removal, or are they too short?
No - The head bolts can be removed with the engine in the vehicle. The studs can be installed with the engine in the vehicle.

Using studs - They are installed hand tight.

Here's a head shot of my rebuilt '902 .....

I think you have to remove the X brace in the bed to get one head bolt out.
(the top right bolt/stud in Sparky's picture)
The X-Brace does not have to be removed to remove all 6 head bolts -- Studs same story.

The ARP studs are .350" longer and work just fine in a stocker as well as a big bore.

5th paragraph from the bottom of the link I referrenced.

Maybe next time - I won't make such a long writeup post .. .. .. :rofl3:

Just a short story on the ARP studs ...........

When I blew the head bolts out of my '902 earlier this Summer - I researched and no one offered a stud kit.

I elected to drill out all 6 holes in the case - And install inserts.

In researching inserts - I evaluated many inserts as to size and length. I also measured the diameter of the hole and depth.

I could have gone with an SAE stud - Then the problem was the "Kit" to install the inserts.

Time-serts had a great kit for the origional metric bolt hole. I decided to replace with the origional thread size. In this way - IF someone had an issue with just one hole - I've provided the Time-sert kit to use and one could use the origional head bolt if so deemed. One might want to read up from the ARP site on what they have to say about studs vs. bolts. It's a no brainer.

And again - I thru Don sourced an ARP stud made for a Subaru Impreza that can be easily modified for use in the Polaris and Sportsman 800cc engine.

This really has proved the best of all worlds.
