Spring plate torque specifications

I ran across some information stating that the factory torque spec of 90 ft lbs for the u-bolts to spring plates will actually bend the the factory plates.

I'm trying to determine if this was a one-off or I should be torquing significantly less for the u-bolts.

So then I gather most people are not torquing to specifications or the lift kits that are all so common purchases with these Jeeps have alternate specifications for torque.

Anyway I guess I will err on the side of caution and torque to 70-80 ft lbs.

Same as above. Anything with a gasket or RTV, anything on something precise, and anything that needs to be even. Keep in mind that OEM u bolt nuts appear to be regular nuts, and some replacements use nylon locknuts. This changes the torque value. What's important is that the tightness is even. I also use the redneck torque settings on my impact.

Either that or the u bolts were cranked down one at a time to full torque.

My lift kit came with new plates [ much thicker ] and larger U-bolts and said to TQ. to 90Lbs.
