Installing shocks

Ok, i have received the new Koni FSD's for front.

Yesterday i did a test to see if i had the equipment
to take out the old hard riding bilstein's and glad to
say the bolts came out nice n'easy.

I used a 1/2" air impact wrench (350 ft-lb) +
1/2" drive impact extension (12" long) +
1/2" universal joint impact + 7/8" socket

I did soak the bolts overnight with PB Blaster, i am
sure that helped.

I am planning on putting the new shock in.

Question> Do i need to use loctite on the threads?
Question> How do i control the torque during install?
My air impact wrench has three forward speeds but doesn't
say what torque rating these speeds have.

thanks
jim

The manual option is always there but very difficult access

I used Loctitie and a torque wrench. I don't trust air tools for torque.

the nuts on my shock bolts are self locking, no need for loctite or monster torquing. if memory serves, i torqued mine to about 80 ft lbs with a torque wrench. the self locking nuts are not going to back off.
i greased the shock bolts before installing them.
my koni's are much better riding than the original monroes with 8k miles on them. they handle better too.

What are the torque specification for the upper and lower bolts?
Is this something KONI should tell me or should i ask Monaco?
The shocks came with no paper instructions.

Also, should there be boots for these shocks?
I don't see any. Have you folks seen boots for KONI FSD?

I put the Koni's on last year in the driveway, you got lucky getting the bolts out my drivers side was a bear, the other side came right out, the backs were easy off and on. Used the all my might wrench to tighten the bolts, they were self locking also. One of the best upgrades to the rig, the 3005 dish is a close second, the new floors are right up there too, the 3 HD TV's aren't bad either, can't forget the Ultra Power, does it ever end, it's worse than the Harley when it comes to mods. Gotta love it. This year I've got a couple of window seals gone so we'll be fixing some glass. But we use it year round, it's a snowmobile camp in the winter months, I'm in it every weekend thur the winter. Want to get one more year out of the rubber.

Torque is a function of the actual bolt size and type. Here is a chart you can use.

These torque specs are for maximum torque for the bolt size and grade. I don't know what the spec. is for the shocks but if you get them too tight you can crush the inner sleeve in the shock. The 80# mentioned earlier sound about right.

I torqued until my face was red
Have taken several trips since and checked the bolts
They all seem tight. I guess "red face tight" works.

If you have eyelets top and bottom the nut is a 28 mm and the torque is 80 ft pounds.
If you have a pin (stud) on the bottom that nut is a 24 mm and the torque is 74 foot pounds.

That came from a slip of paper in the box each Koni shock came in.

So Caymann, how do your new Koni shocks compare to the old Bilsteins?
