So i put on my lift last week and as I was tightening the ubolts a nut just stripped right out and twore all the threads up and shot up....

I put on another set and torqued them to 55-65 ftlbs somewhere in there and after 50 miles i went to retorque them and one of the bolts is stripped again! I ****ing hate these things, they are meant to hold your axle to your vehicle and they cant even handle 65 ftlbs?

 

did you replace just the nut or the nut AND U bolt after the first stripped?

 

get real grade 8 u bolts....

 

Forget U-bolts period. Check out T&T Customs U-Bolt Eliminators.

 

Theyre expensive lol, i mean ubolta are too but i only need 1 new ubolt

 

$6.99 for grade 8's at most auto part stores.... and you get 2....

 

go to a spring shop and get a set bent up for you. they are fine thread made from black tool steel. so i think they are actually grade 12 steel with 1/2 inch thread.

 

So did you replace both or just the nut?

 

The nut shot up the u-bolt stripping every thread in its path of fury

It's happened on 2 u bolts so far, even the legit $15 a piece napa u-bolts

 

sounds like you have a bigger issue.

have you checked that everything is sitting correctly and your mounts on the axle are fine? lift blocks?

 

I have never had an issue with my $6.99 ones and I have 100 ft.lb. on them... (well did it looks as tho they need to be re torqued)

 

These are Grade 8 bolts from a machine shop.
I'm running more leafs then most people lol Even with 9 leafs and flexing completely these are great u-bolts not a single prob.

 

How are you two even torqueing those u-bolts without cutting them? Could that be my problem? I cut them and then torque them down.

 

I just replaced my bottom 2 leaves with s10 main and second leaves as a bastard pack, 4 leaves total and now that i think of it, the nut/bolt that strips is the passenger side, say you are looking at the wheel well, these are the nuts : . Its where the missing dot is. That always strips dunno why!

 

I own these :



I typically cut them at some point tho
