What did u do to your raptor today?

Messaged deaver to see what they recommend on torque spec for the leaf spring u-bolts and got back to me asap, 120ftlbs just incase anyone was wondering. Then after yesterday and a few weekends ago going back and forth from the garage to the computer I figured why not just print off the main torque specs laminate and just leave them in the garage for a quick reference.

Interesting, the ICON RXT leafs show 145ft-lb. States to torque to 40ft-lb first then final toque when on the ground. I like actual torque values than the stock showing torque-to-yield as that is so subjective.

Yeah when we were doing them yesterday I wasn't sure because factory spec does say torque to yield. I think when you go aftermarket anything it kinda changes and should go by that manufacturer spec for the part for sure. @JanT just don't forget the retorque.

Realized same thing when i was doing mine. Laminated torque specs and keeping it in the truck, since service place don't know any of these here.
I just changed my U-bolts week ago and torqued to 110ft lb so thank you for right spec.

Here is a nicer torque spec sheet.

SUPER important to retorque with the Deavers. I checked mine weekly for about a month, and each time they took a little.....

Not subjective at all. Just involves a bit of math and the right formulas. Where the issue comes in is knowing what the material is. One you know what the material spec is, you can look up the yield strength....

But yes, I agree. They should simply provide a torque value. By stating "torque to yield" leaves the determination up to the mechanic, who without the proper inputs and knowledge won't be able to torque the U-bolt properly.
