Guys & Gals:

I have a 2008 F150 Supercrew that I have installed a 1.5" AS leveling kit on. The truck sits 1/4" higher in the rear, I want maybe 1/2" to 3/4" more lift in the rear to net me 3/4" to 1" total.

What would be better:

(1). Shackles if they make them that small.

(2). AAL

or

The option I just purchased from AS; they cut me 2 peices of leaf spring that measure 7/16" thick and 5" in length, drilled them and gave me 4 new longer center bolts. Here's some pics of what AS sold me:









I am very very scared about taking apart the rear axle from the leaf springs.

Any suggestions ?

As always, thanks!

Hey, I have actually done both the items you listed (lift shackles and the AS 1/2 spacers and longer bolts).

I did the shackles originally, and I think I got about an inch of lift, but my springs started to sag a little in the last year, so I did the 1/2 spacers and its right back where I wanted it.

You might try those spacers first, and if its not high enough for ya, you could always go with the shackles later. Good luck!

As far as taking the leafs apart, its not all that bad.. the U-Bolts come off pretty easy, the biggest pain I had was getting the stock center bolts out of the leafs.. ended up having to cut them off, as they wouldnt come un-stuck with PB and an impact wrench.

 

In terms of easy of install, the shackles are much easier and cheaper. I am a big fan. Gave 1" of lift. Suspension Max sells springtech shackles for $50 shipped

 

Ive been wondering how this works? Are they just shorter shackles?

 

Exactly. I have multiple posts about this

Well, I have just completed installing the 1/2" spacer plates and with the generosity of my work letting me borrow their garage with the lift it went extremely smooth.

I'll have to say; even though it's only 1/2" it visually makes the difference I was looking for.

I'll take some after pic's and post them shortly. I just have to finish my 2nd. NEWCASTLE in celibration, and being that I've had no breakfast I'm a little dizzy. So pardon the blurry pic's when I get back.

Sincerely,

Here are the after pic's ...

Nice job! Good to see another way to lift the rear. Did you have enough thread to reuse U bolts and how much did this mod cost?

 

Thanks, I spent $55.00 with AutoSpring. They are the same folks I purchased the leveling kit from.

There is about 1/4" of thread left on the u-bolts after installing the spacers.

I re-torqued the u-bolts to 100 ft-lb. and the centering pins to 65 ft-lb.

Thanks for the replies ...

Hey guys, I just skimmed through some posts and found that I was supposed to have used a "star" method when I retorqued the u-bolts. I kinda sort did that but did not strictly stick to it because I was more worried about having the threads even as possible.

I retorqued them to 100 ft-lb.

Should I loosen them and retorque using a strict "star" method like lug-nuts, or just re-check them after a couple hundred miles?

Thanks!

I think you should be fine, but I am always one to stick to the letter of the law. At least when it comes to my truck. My rap sheet would beg to differ.

 

Take a look at how many threads are left beyond each nut. That will give you a pretty good idea how evenly aligned/torqued the U-bolts are. From what I can see in the pictures, things look pretty even...you should be ok.
