1" full leaf packs?

Im wanting to do 2/1, but I dont want blocks or AAL. Would prefer to do a quality full leaf pack. However, I'd like it to be leveled. The only brand I can find that has 1" full leaf packs is Deaver. Theyre also 4x more expensive than any other typical 1.5/2/2.5 leaf pack I can find at 800 bucks. Can anyone suggest some options for me?

 

Places like this can make a OEM spring with a proper engineered extra spring to give 1" Often they are better metal quality.

With leaf springs you need to lower expectations, getting exactly 1" is difficult without using a block spacer. They can often be more or less even if advertised as such.

Honestly with a brand new truck the add-a-leaf makes the most sense, get the value out of the springs you paid for, then replace them down the road. But its my 2cents I know where you're coming from.

 

buy once cry once

 

Ive been reading that AAL rides rougher/stiffer than a full leaf pack. Do you think this is something I should worry about? AALs also only come in 1.5" minimum, but I figure at least that will be *closer* to level.

 

1” springs ride rough as well, there’s no real way to get lift out of leaf springs without creating a harsher ride when unloaded. Except blocks, which are so common that they are included in the trd factory lift kit.

I’d say a icon 1.5 progressive add a leaf is best, but the block actually suits you the most. They have no negative impact on driving when only 1”

Again upgrade the leaf springs later on 5 years from now. But for now is what you have. It’s just my opinion, all choices are good.

 

Gotcha. I appreciate the input. I shall go w the add a leaf. I may sway away from the block for medium offroading. I know it will get me that exact 1", but function over aesthetics I figure.

 

Im running a cheap add a leaf now and it’s nice when you load it up and doesn’t squat. It can get a little choppy on back roads but that’s why a quality rear shock to match the lift is critical.

 

I’m not 100% sure about this since I’ve not found a good article on leaf spring design, but I suspect a leaf spring can add lift without being stiffer by being made longer with more arch. That was the logic I used to go with a OME Dakar leaf pack instead of an add-a-leaf.

 

Genuinely curious as to where to get pair of full lift leafs for $200.

 

They are going to be “previously owned”. I gave some away my OEM leafs to some one who was going to add one leaf to his leaf pack.

 

Of course but that's not what it sounded like he was saying.

 

I agree. I've gone through a single AAL, a progressive AAL, and now I'm the Icon springs. The single leaf broke, the progressive set started to sag after about a year. @IEsurfer is not wrong here.

 

Weigh your truck on each corner and send specs you want to Alcan, They will make you leaf springs. Roughly 1,000.

 

Can you elaborate on this some more?

 

I’ve yet to see a lift pack that doesn’t have more capacity.

Capacity on leaf means more rigid unloaded in my experience.

 

More capacity than stock, what is stock leaf pack weight capacity?

 

AFAIK, the OME Dakar mediums have the approximate same load capacity / spring rate as stock, but they are longer with more arch.

• The "Medium Duty" leaf pack (EL111R) will provide approx. 2.75" lift (2005-2015 Tacoma) or 2.0" lift(2016+ Tacoma) while supporting 0 lbs - GVW

I have them and my subjective experience is that they are no stiffer than stock, but I can't say I tried to measure the spring rate in any objective way.

The challenge with leaf springs is that the manufacturers don't publish spring rate specs so that you can compare them. I suspect the reason is partly because leaf springs don't have a constant spring rate (i.e. Hooke's Law does not apply) and publishing a spring rate curve or table would be too confusing for customers.

 

you could be a little more constructive with your tear down.

 

I forgot to say that the RXT springs ride way better than the stock springs. They're also adjustable for the weight you carry. Option 1 gives about 1.5 inches of lift.

 

I couldn’t remember which spring did that I checked rxt but the Dakar makes sense. We usually put the heavier versions on.

When I used to work on jeeps it was more common to see arch lift that would ride near the same but I have seen it as much with Toyotas. Maybe it also coincides with truck owners typically wanting more weight capacity to go with lift.
