Tundra Rear lift issue

ill try and make a long story short.....I drive a 2018 crewmax platinum with 12k miles

I first installed the Toytec shackle @ the 1” hole and I felt the rear then rode like s***. Also looked like my rear leafs were on the flat side. Hub measurement was 24.5” or 39.75” ground to fender (running 33”).....toytec couldn’t help me so I decided to try the Icon leafs.

I went with the 51200 leaf pack. Installed yesterday and I lost height...I now measure 24.25”

The leafs are supposed to add 1.5” the ride is a little better.

Am I missing something why I barely got any lift with these options?
Are my brand new leafs already flat???

Thank you for your input!

 

Did you re-use the stock overload leaf? It’s needed for 1.5” lift.

 

I have the main Toyota spring, the Icon leaf pack and ONLY the thick spring, did I need the other one attached to it as well?

 

Picture?

 

I’ll get a picture soon, do you have this setup? I’m thinking I’m short a leaf now, but pretty sure I followed icons directions

 

If you’re only looking for 1.5” I’d ditch the shackles and use a block. Wouldn’t affect ride quality.

 

No I do not have them, but installed them. Yours look correct. I’m no further help, but this is my 18 rear measurements with a 1” lift block(provided exactly 1” lift) on 33” tires. Mine is a pig, full armor, sliders, gear etc..

Driver - 40 7/8” ground to fender, 25 1/8” hub center to fender
Passenger - 41 1/8” ground to fender, 25 3/8” hub center to fender.

 

Are the shackles suppose to be angled back like that?

 

So I just took a good look at my leafs and they appear to be in a “w” shape....

How are they flat already!

 

After seeing your pics, I wonder what would happen if you removed those shackles and put the stock ones back on. It would alleviate some of that press down on your leaf pack.

 

Those are the stock shackles
