3rd Gen Saggy Leafs?

I dont think its the shocks, they are pretty new and many people run them without problems, all i hear is $$$ ahaha

 

wheelers said that the rear shock is good for a 2.5" lift

 

i c. im gonna try and go with a single Deaver AAL for now. im just running a camper for now hopefully it will hold up for the time being. i have some stage 3 deaver leafs on order and gonna wait till i add more weight in the bed before i put the stage 3.

 

kinda says it, but plays it safe with wording. haha. im messaging with eibach right now to make sure a 2 inch leaf would be "safe" im sure it is, but better safe than sorry.

 

I’m guessing your truck is just fine and you don’t need to replace anything unless you just want to.

Rather than posting a picture (which looks normal), I suggest measuring the distance from the center of your hub to the edge of your fender flare and reporting back.

We also need to know the height of your spacers.

I suggest also inspecting your shocks for leaks. Shocks also have an effect on bottoming out.

Here is some food for thought about spring rates.

all leaf springs sag over time. just a characteristic of steel.

 

What does that even mean?

 

Are you sure about that? I believe ferrous metals are known for their resistance to fatigue failure due to repeated strain below a particular limit.

It means that if you look at the leaf springs on just about any Toyota they look basically flat instead of concave.

 

Why do you call that “saggy” and think it’s a problem to solve? Is it the aesthetics?

 

just going by what i've seen. i'm not an engineer.

 

this thing looks awesome. has anyone ever installed these on a taco? looks like they'd eat up speed bumps like it was nothing

 

I think you might have some misconceptions about how suspensions work. Assuming you are not hitting the bump stops while driving over a speed bump (the likely case), you will not improve your ride quality by stiffening your springs (increasing the spring rate). You will just make it worse. The proper thing to do is to decrease the spring rate (and possibly add some more damping). CAVEAT: you will potentially decrease your payload capacity as a trade off.

Springs settle.

My combo: Deaver single AAL plus 500# Sumo Springs. Gives 1,5” lift, keeps the factory pack stock, including overload, and offers protection from excessive load through the bump stop. After one year and 27,000 miles, including frequent moderate off-road, hauling around the house, and pulling a 2,500 pound trailer, the rear has settled 1/4”.

Good shocks help, too. ADS here.

 

How would a block cause a leaf spring to sag?

 

I took out the blocks and put in icon aal , quite happy with it!

 

A flat spring can move up and down in equal amounts. This is the way Tacoma springs come from the factory, with only a slight arch. My springs were pretty much dead flat brand new.

When we lift our trucks we can either put in a more arched spring, or a block and keep the flat springs, depending on what weight we plan to carry. People get obsessed with thinking the springs should be arched, but that’s not always the case.

 

don't know. leverage i guess.

 

Urban myth.

 

The only way a block affects a leaf spring is by increasing axle twist forces causing spring wrap. With a small block this is unnoticeable... using a 6 inch block would be quite noticeable. Blocks are absolutely fine to be used in a moderate lift and will not affect ride quality or spring life in anyway.

I prefer a block for small lifts and a full leaf pack for larger lifts. I have seen too many trucks sagging in the back because the AAL isn't strong enough to resist the 5 other leafs that are trying to return to thier original shape.
