They should not be making that much noise. When you preload them, just make them as tight as you can with your hand.
I’ll be installing my stifflers longbars soon. Are yours still noisy? Is there anything I should know before I install them? Other than weld the u bolts. I plan on using a 4 post drive on lift.Yeah I gotcha guys. I just installed them and they're great! I have them just barely snug on there, I guess I should adjust the preload more tight, cause I can hear them clunk/squeak when I'm coming to a stop or driving up a driveway. I've re-torqued them 2 times already. They're bolted on right.
Other than the noise, man they're great! I can totally feel the difference.
I don't think you will find much noise. The adjustable rod ends have seen improvements in the last couple of years. As far as preload, I would get the bars adjusted where you can slide the bolt through the bracket and rod end, tighten the bolt, and then tighten (add) about one twist of the bar. That should be good. There should not be a need to weld the bracket to the axle tube. If you have a higher hp truck, it tells you in the instructions to weld a stop to the axle to eliminate rotation of the bracket on the axle.I’ll be installing my stifflers longbars soon.

If it were me, I'd go ahead and weld a stop on there. If you don't still have your instructions, you can download or view them at Stifflers (buystifflers.com) website. Feel free to reach out to me at any time for assistance or questions. :rockon_fordThanks,
What HP range would it be appropriate to weld the U bolts to the axle? I should be at 600hp on pump gas but I’m setup for e85 so will be making more power later on. :smt023
Now that’s customer service at its finest right there!If it were me, I'd go ahead and weld a stop on there.

I appreciate your input on this :bigtuThere is a little bit of misconception here that the adjustment that is available on Stifflers bars is to "dial-in" your suspension to see quicker 60' times. The MAIN reason you see the adjustable rod ends is because it was felt that having a rod end that was solid vs a rod end with poly bushings was a better design. Could have just welded the rod ends on there instead of having a threaded end, but was felt the threaded end could be beneficial in bar fitment. An individual could play around with the preload on the bars and see how there truck would benefit, but it was determined that just adding one twist of the bar after install to preload them was sufficient. I hope this is of some benefit to the discussion.
From your personal experience of dialing in a truck with stifflers long bars, did making changes to the preload alter how it launched and how well it hooked or didnt hook?An individual could play around with the preload on the bars and see how there truck would benefit, but it was determined that just adding one twist of the bar after install to preload them was sufficient.
