On Friday I'm going to add some OEM 1 5/8" blocks in the back. I bought them from HiVoltage14.4 (awesome guy to deal with I might add) and I have the larger U-bolts that go with them.

What are the torque specs for the U-bolts? I have access to a torque wrench and just want to make sure I'm doing everything correctly. Also, I'm guessing the best way to add these is to just jack up the leaf springs on each side one at a time?

Thanks for any input.

 

Anyone?

 

I dont think there are torque specs for the U-bolts when I put my AAL in I never read or have seen anything about making sure you meet torque specs. I just turned the bolt till it wouldnt move anymore.

 

the torque spec for the u bolts is 90 ft/lbs i jsut put a 6" fabtech lift on my truck and it was 90 with the new u bolts so if put them to that and you should be good

 

Thanks for the replies. Also, to aPINCHbetter90: Did you have to re-tighten them at all? Did they loosen up at all?

 

i drove for a week and had to re tighten then cause the u bolt stretched alot and i turned each nuit like 2 times so id re check them in a week or 2

 

Cool. Thanks so much for your replies.

 

Last question..

When adding these 1 5/8" blocks in the back, do I need to re-align the vehicle and re-aim the headlights?
