Dv8 rear lower shock skid plate- torq setting!?

[Combustion_King]

I was just reading my install instructions, it’s saysbtorque the shock bolt to 350#, Is this correct? Seems like a lot, my impact goes to 250#. Unless I blindly gun it tight?

I included the instructions-

What’s the stock setting?

Yes, it is 350lbs. A 3ft bar will handle it fine. Put your back into it.

The guy who installed mine made a comment about the amount of torque that it specified. I forget the exact number that he said but he had brought it up because it was pretty high.

I’m not worried about getting it off, just re tightening to the correct setting. Def seems high

This is why I went with the Barnes shock plate.

I thought that number was pretty high so I called Ford service at my local dealership. He said they don’t torque anything that high around the shocks. Definitely didn’t want to try it myself after I heard that. Others have installed them though, so I guess it works.

I guarantee many of us aren't putting them back on with a torque wrench. If I can take them off with a 3 ft bar, I can certainly put them back on just as tight with it. How tight? Don't know. It's enough.

true that, lol I know i can get them to at least 250, im assuming the numbers so high bc the design isnt like the bolt goes through, but rather slides between

Have no idea what the rational is for the lower shock bolt being that high, but it is. I've never seen any other coilover that high. I'm sure mine are over 300lbs. When I start bending a 3 ft bar I figure it's tight enough. They certainly aren't going anywhere.

im gonna just check the specs of my impact gun and tighten that way. pretty sure it goes 350 plus

Torque specs are getting out of control.

The pitman arm on some year Super Dutys is like 450 fuckin lbs.

I bought a cheap 600 lb-ft 3/4 drive torque wrench ahead of installing my Icon suspension.

I purchased one of these Milwaukee 1/2” impacts. Has made a world of difference working on the truck.

Broke the rear shock bolts loose by the second click on setting 3. Watched the metal deform running it back on, setting 2. Everything is pretty much instant with it.

Engi-nerd here. Technically, since it’s a torque spec, it’s 350 ft-lbs, not 350 lbs. With any torque, the longer the radius of the moment arm or lever from the pivot point, the lower the force required at the end of the radius to meet the torque spec. So use a long breaker bar to give you better leverage and lower the force required.

For example:

• With a 1 foot breaker bar, the force required at the end of the bar is 350 lbs (350 ft-lbs / 1 foot = 350 lbs).
• With a 2 foot breaker bar, the force required at the end of the bar is 175 lbs (350 ft-lbs / 2 feet = 175 lbs).
• With a 3 foot breaker bar, the force required at the end of the bar is 117 lbs (350 ft-lbs / 3 feet = 116.67 lbs).
• With a 4 foot breaker bar, the force required at the end of the bar is 88 lbs (350 ft-lbs / 4 feet = 87.5 lbs).

Personally, I think that particular torque spec was decided by a lawyer rather than an engineer. At anywhere close to that torque, that bolt and nut combo aren’t going anywhere!

I got the 18v Milwaukee impact, does like 750ft/lbs

i found a buddy at work that has a snap-on tq wrench that will do those specs, so gonna borrow it and hopefully bang these out this week.

Gütentite. Cross threaded or torqued to spec, tight is tight

That bolt definitely has an ugga-dugga spec.
