How much sag to expect from Leer topper?

I'm in the process of ordering a Leer 100XR topper and lifting my Taco, and want to know roughly how much rear sag I should try to compensate for when I pick my lift setup.
I want to end up with a very slight rake and am planning on going with 5100's all around, Eibach coils up front (Bil's at 0.85) and either a 1.5 or 2" AAL, depending on how much sag I get from the new topper.
Anybody have any experience with this? My truck is a brand new 2014 TRD Sport DCLB.
Thanks

 

Anyone?

 

1) Find out how much the topper weighs.
2) Measure the between the ground and the frame.
3) Add the same amount of weight as the topper into the bed of your truck.
4) Go for a drive
5) Park in the same spot
6) Measure again.
7) The difference will be the amount of sag you can expect.

I've never had one of those toppers, and every truck's different, so that's the best way of guessing I can suggest.
Of course, your lift will stiffen your suspension, so...

 

I had a 2007 DCSB 4x4, 5100's up front with Eibach coils (Billies at 0) and I installed the Icon 3-leaf progressive AAL in the rear with a TSB leaf pack and I kept the overload leaf in place. It's a 1.5" AAL but is intended to be run without the overload leaf. Since I kept the overload, I ended up at 2" of lift for the rear and that gave me quite a bit of rake. If I had kicked the billies up to .85, I would have ended up with a very slight rake.

Here's a good side shot of the setup. Keep in mind, I have an extra 200 lbs in the bed also aside from the shell weight.

 

No noticeable sag on mine....all stock shocks, but I did have the rear Leaf spring TSB done.

 

How long ago did you have your shell put on? My TSB leafs lasted a year with the shell before they were flat and being completely supported by the overload leaf.

 

Edited dates....getting old!

I bought my truck new in May of 2011 and had the cap installed 3 weeks later. I had the TSB done in December of that year because suspension was bottoming out on the slightest of dips in the road with a light load. I've had it freighted numerous times since and don't even really notice much sag. I think the new leaf springs are holding up nicely as my rear is still sitting higher than the front.

Here's a more recent picture too.

 

That's awesome! Mine was an older model so maybe Toyota is finally getting better with springs. My back end was always higher than my front end, but I started noticing it was riding like crap. On a big bump, the back would buck hard. I came to find out it was because the leafs were flat and my suspension was basically the overload leaf. It wasn't bottoming out, just riding on that thick bottom leaf all the time.

 

My 2009 Factory 4 leaf " TSB " pack was flat after 4 months of carrying a 300lb toolbox

 

My 2012 DCLB Sport dropped between 3/4" to 1" with A.R.E Z-series installed at 2500 miles. Stock suspension, no mods. Factory 3+1 leaf pack.

 

If you weigh close to 200 lbs just get in the back of the truck and see how much it drops. If your stock the guy above is going to be identical it sounds like if your not stock test it out with the approximate weight of the topper back there. I hope it does not drop it an inch like the above man that seems like alot. The amount of gas in your tank will change the rear end height as well. I have a 3" lift with rear 1.5 AAL and its sits higher in the rear when low on petro.

 

Buy some hellwig helper springs to help eliminate or prevent sag. I put the ez550's on my dcsb and it didn't sag one bit after the topper install. They work with any leaf pack.

 

Ok thanks for the input guys. Do the new Tacoma's still suffer from taco lean? Should I throw a 1/4" spacer on the driver side when I do the install?

 

This is about identical to my stock 2013. Dakars coming soon...
