Shackles not vertical after new leaf springs

Hello and thanks ahead of time for any input. I decided to tackle the 4" lift kit today and I'm at the point where the instructions call to torque down the (New) spring to shackle and spring to frame . I'm concerned because in order to make the new leafs fit I had to loosen the top set of bolts on the shackles and push the bottom half of the shackles forward (towards the rear of jeep) . Now that the U bolts and spring plates are in place and torqued down the shackles are not vertical . They are more at an angle nearly diagonal. Is this normal/something that will be corrected when I get weight on the springs or ??? .
Thanks again YJMason

did you tighten it up while it was in the air or on the ground?

what direction diagonal?
Who's springs?
What did you tighten the bolts to (should only be about 35-40 ftlbs or they wont move freely)
is the rig sitting on its own weight when you finish tightening the spring and shackle bolts?

I think mine started out "not verticle" too, but they straightened up.

The springs are from Rough country . They measured the same as stock from Bushing eye to eye . I havent torqued down the shackles (uppers or lowers) or the rear spring to frame bolts yet . Had to take a break till tomorrow . I'm not to the point yet to where I can put the wheels/tires on yet still have some other components to install before that so the axle is resting on the springs and the front end is off the ground supported by jack stands on the frame rails . I really didnt want to go to the next step which is torquing down the spring bolts until I knew what was going on with the shackles which are diagonal with the bottom of the shackle being closer to the axle than the top like this (side view from drivers side " \ ")

Maybe I'm not getting this but are you talking about the front or the rear? If its the front and you are saying that you had to angle the shacle toward the back then you are fine . The springs are in "full droop" and will compress out once the spring is under load and settle in ... If talking about the front and the shackle is angled foward with no load then its possible you have the rear/ front springs swapped ?

That's normal if the axle is not on the ground. My guess is typical RC and their instructions are wrong. I would never torque shackle bolts unless the weight of the rig is on the tires. So keep moving on your other projects then get the rig back down on all 4s before torquing the shackle bolts to 40 ftlbs regardless of what RC tells you.

Also when its all said and done you want a little shackle angle away from the jeep both front and rear it helps the spring compress and droop out a lot better then a verticle shackle angle.

thats normal but loosen those bolts or they wont swing into place when you set it down. The lift should be installed and the jeep set down before anything is torqued... should say that in the RC kit instructions. Very important!!!

and... how many bolts did you have to cut?

The RE instructions want you to torque everything down before putting the wheels on the ground, too.

Will it not settle properly?

From the RE5505 PDF on their site:

15 Torque spring eye and shackle bolts to factory specs.
16 Install front tires.
17 Lower front of vehicle.

not trying to start an argument but...

16. Do not tighten the springs at this time. The spring hardware will be tightened once the vehicle is on the ground and
the suspension has been cycled. Tightening the hardware at this time with the vehicle off the ground could
result in a stiff ride.

17. Install tires/wheels, remove jack stands and lower vehicle to floor.

18. Tighten the front spring’s shackle mount to 90-95 ft /lbs
and the frame mount to 100 ft/lbs and install the track
rod on the track rod bracket with the supplied 12mm x
50mm bolt, nut & washer on the head of the bolt against
track rod bushing. Refer back to Photo 6.

this is strait from there website http://www.roughcountry.com/install/1620N2.pdf

^ this (SteveO's) is the right way to do it. Those other instructions are out of whack... If you lock it all down and hit the road without setting it down first you will feel like your riding on a mechanical bull.

I'm with Irongrave, torque to 40 ft lbs. 90 to 100 ft. lbs. is way too tight.

Ahhh... I was quoting RE, not RC.
