Was originally considering a custom rear spring pack replacement or the ones available through some of the other vendors but after I test drove the CALMINI X a while back I was impressed. At ~ 50% of the cost of the other spring pack replacements or custom it was pretty easy decision for me, plus I actually preferred this design for my application anyway, rather than the 10-14 springs in a pack the others offer.

IMO the on-road ride is much better than when I had the stock pack, with a longer shackle or when I added either a single AAL or a 3 pack.

Off road even more impressive; smooth & controlled with virtually no wheel/axle hop, they flexed so well I didn’t notice I forgot to take the sway bar links off until they day was half over.

Anyway that's my 1 week water cooler review

Those look great! Didn't know they had those!

OK, just checked their site and didn't see them? How much $$$? I actually really like my SLR 3 pack, but my left side is riding lower than the right due to my original springs being lower on that side, so someday I might want to get a whole new set.

They are listed under the SAS section.

Which is my next question...can you run these without the SAS or are these simply designed for the SAS kit?

~3.25" lift for me so with a stock shackle might work with a full IFS front lift but check with the Manufacturer on that.

any one know what the weight limit is on these? i plan on buying them when i do my swap but i want to make sure they don't sag too much with the bumper/tire carrier and tools and other gear in the cargo area.

box, are those the new 34's on there?

That's a damn good price!

Now if they'll only make a spring-over version for the Frontier...

Ah, now I see! Yeah, damn good deal! I don't see why they couldn't be used without the SAS. Calmini probably had them made for the SAS system, but that doesn't mean they won't work without it. Just a matter of getting the right shackle length. Worth a call.

Definitely... when I sus-lift there is no way I'm just going to band-aid my sagging stock springs with an AAL. I want brand new spring packs.

If anyone else does this to a non-SAS truck, please post up about it!!!

Questions I'd like to have answered:
1) Is that 3.25" lift with stock shackles, with the regular aftermarket Calmini shackles, or with some newfangled SAS-kit shackles?

2) Are replacement U bolts required? Will the regulgar replacement Calmini ones work?

If the leaves are designed to work with a particular shackle length...the shackles will traditionally be responsible for a good proportion of the wheel travel.

So - You might get the total inches of lift you want...but, maybe not the articulation...as lift leaf only systems traditionally do not articulate as well as leaf/longer shackle combinations.

Food for thought.

I'm calling Calmini in the AM about this. It's exactly what I'm looking for. I'll let you know tomorrow night. If it's fine for non-SAS Xs, I'm ordering it.

Is there any reason not to just use a stock Xterra spring in the spring over position? That should give enough lift to match the front. All you will need is a new positioning stud....

As I recall the spring length for the Frontier and Xterra are different so that would not work.

So - any answers on how much lift the pack gives with the OEM or what Calmini shackles....or, the weight bearing capacity...as in can it last when loaded down by the typical rear bumper carrier, tools, spare parts, armor, etc?

If not, is there a beefed version for extra load situ's?

Called Calmini today. The guy said it's probably for SAS only though he wasn't 100% sure. His thinking was because it's only on the SAS page....

BUMP
It's this or Deaver for me.. Anyone get an answer from CALMINI yet as to wether these'll be fine for their 3" SL or not?

What a moron (not you Jim... the moron you talked to)... of course they are just selling it for the SAS kit... but that doesn't mean it wouldn't work just fine for a non-sas setup (doesn't mean it WOULD work either...) The point is that we need an answer from a technical designer-type guy that knows how much lift you get from the pack etc - not a salesman.

Call and ask for Steve, maybe they could use a guinea/tester or make a slight adjustment for a 3” lift.

With a stock length shackle worth a try with a full 3” lift up front although might have a near stock stance unless you run an aftermarket rear bumper/tire carrier with the extra weight.

My three month review

Still hate the stock rear hanger step think I’m going to cut all the extra off ~ 11 3/4" up to the bushing mount & weld in a strip just before that for support. This way my tire is a lot closer to getting grip on the rock/ledges that I catch on those low riding rear spring hangers. Won't make as much difference on the passenger side with the gas tank but maybe a few inches less?

Rear leaf packs have NOTHING to do with an SAS up front.

There is absolutely no reason why this springpack would function differently because of front suspension.

I could put them on my X! (although they would look funny)

I think the only real question is the length of the shackles that are used with the SAS'd suspension kit.

We know the stock shackles are 3", and every 2" more than that adds an inch of lift, etc.

We know the total lift for the SAS kit, so the difference in lift, attributable to the leaf pack alone, would be the total kit's lift, minus the SAS kit's shackle's contribution.

All the other questions revolve around how much lift from just the leaf pack....and, that's how to find out.

Someone with the SAS - measure eye to eye on the shackle...the rest is easy.



(Assuming that the axle mounting point on the new leaf pack is centered the same as the OEM pack, and not moved fore/aft to compensate for travel, etc...)

You can allways de-arch the spring pack to your desired height if they are too tall.

Or add more weight.



or use shorter shackles.



etc.

The shorter shackle thing seems to be the best option if relevent.

Shackle I’m running is the same one in the 3” CALMINI IFS lift kit & the only one they offer as far as I know ~ 5 ¾” eye center to eye center.

Brian,

I also have the same one.

OK then!



The SAS is a 5" lift...the shackles give 1.5" of it, so the leaf pack, by itself = 3.5" of lift.

So - using the SAS leaf pack with the OEM shackles would be a 3.5" rear lift, pretty damn close to the 3" lift up front.

The OEM shackles are about 3" long, so to loose another 1/2" would require a 2" long shackle.

The 3.5" is close enough, especially considering the typical sag over time the rears go through anyway.

Looks like the Calmini SAS kit leaf pack would therefore work with the stock shackles and a 3" lift upfront.
