To much in trunk.

It change the ride height. And for some reason one side of the of the truck. Toe angle is on extreme side, still within factory specs.

Plus being a Lexus service Technician I got the benefit of the Hunter Hawkeye alignment machine as my disposal.

Also why I drained and filled my WS trans fluid at 15k, 25k and 40k.
Along with the brake fluid.

The transfer case is another story. Those LF fluid is $$$$$ for 1 qt. Even with my discount.

 

Have a look at hotshot off-road… a sponsor on here. I saw them post the icon rxt pack for $630 shipped recently.

 

Do it right from the beginning. I have a light weight regular cab. I broke a single AAL with about 800 or 900 pounds of soil. Then I replaced the single AAL with a progressive 3 leaf AAL. That ended up working fine until I put the RTT on. After about 6 months of that I was constantly bouncing off the bump stops. I then sprung for a full leaf pack and haven't had a problem since. So just save your time and don't waste your money. Do it right from the beginning.

 

OME Dakar medium duties fixed my rear squat from the added weight and rides very well.
Pic cause why not…

 

I’ve had my Headstrong 3 leaf AAL on for exactly a year. With a camper shell and regularly loading the bed with an additional 300-400 lbs. of work gear several times a week, I’ve measured 1/16” of sag (measuring in the same spot in my garage) since the day I put it on - So virtually no sag after a year. If you use your truck to offroad every weekend and are always flexing out the suspension with a lot of weight over it from a shell, rack. RTT, etc… then I agree a leaf pack is the best option. However, I think these threads tend to lead people to believe a 3 leaf AAL is just going to give up and die after 6 months under normal use, and that’s misleading for the vast majority of people on here who don’t drive “apocalypse survival” tacos. I have no doubt my AAL will still be riding high for several more years, even with my topper and hauling shit all the time.

 

I agree with this. If you seldom if ever flex or really load your suspension the chance of damage/squatting your springs is minimal. I do use my vehicle off road which probably shortened the life cycle of my two AALs. So are you going to use that cab and RTT and get out there? If so I stand by a replacement leaf pack.

 

I had a 3-leaf AAL on my truck for about a year also and it was fine with the HC bumper and camper shell for a while, then I added a swingout and spare carrier and I was sagging and hitting bump stops shortly thereafter. I've got u402 stage 2 leafs now and figure they're gonna be good for the long haul.

 

I do hit rough trails and get into some sh*t. If I di go full pack do they add a lift or do I still need my 1 inch block?

 

Generally yes an aftermarket leaf pack will raise the truck. There’s no need to combine one with a cheap block.

 

Awesome, I hate the block lift.

 

I think it’s mostly the constant weight that should determine if an AAL will do the jog fine, or a full HD leaf pack is needed. My AAL handles the constant 200 lb. weight my shell with no problem (it sagged it down immediately from 1.5” to 1”of lift, but has not sagged further any significant amount. The ~40% of the time that the bed is full of a few hundred lbs. of stuff removes all rake and the truck sit level when loaded. So yes, if I had a steel bumper/tire, etc… and still loaded up the truck with the stuff I already do now, I would for sure buy full new leaf packs. But in my case, which I think is still more than most people as far as weight, my 3-leaf AAL is perfect, especially for the price. And I notice no difference in ride quality vs. stock.

 

Just stumbled in here and wanted to add my $0.02 on getting a full leaf pack. I run the Deaver U402 Expedition Stage 3, gives approximately 3 inches lift at 700-1000lbs of constant bed weight (on a 2nd gen). I believe it gives .5 or so less lift on a 3rd gen.

I ran them originally under my AT Habitat buildout with rear swingout and such. And I tow regularly. Now it's supporting my Camper, but with the ability to unload I'm often running with no weight whatsoever in the rear, and it's amazing how well it still rides. It's a bit stiff in normal driving, but just last night I decided to detour down a street we call the speed bump road, lol. Hit large speedbumps doing around 30 and I was amazed how smooth it was. As was my wife. (running Bilstein 5160s in rear, basic icon adjustables up front).

Yes, Deavers are expensive. But you would never regret them.

 

Not to be off topic but my truck came with what the previous owner said was an Icon leaf pack but he also gave me two extra leaf springs from that kit. Wondering how the kit works. The truck rides fine but better of course when I have a good 250-300 pounds in the bed…

 

Like others have said, go full leaf pack to replace the block. Your going to have some rake with more lift in the rear unloaded. I have the TRD lift and replaced the block and springs with Icon RXT on option 3, and a 3 degree shim as long as I was in there. Also did a u-bolt flip kit with Duro bumps. AND do extended rear brake lines! At full droop, the TRD shocks fully extended before the springs (probably bad) and the brake lines are starting to get tight in my opinion.

This is my pre-camping daily driver loadout with RTT, awning, rack, softopper and sliders. In the bed is a bed mat, Hy-Lift, full size traction boards. And misc stuff in the roof boxes. I estimate around 400 lbs daily. It rides very smooth and not harsh at all. When I'm loaded for camping, I can still hit the bump stops sometimes.
