I'm currently running a poor man lift with a spacer up front and shackle in the rear. I also have adjustable Billstein 5100s with the fronts adjusted to 1/2" above stock height (one notch on the shock) to preload the front springs just a tad and compensate for the weight of the winch.
The rear end sits just a little too low for my liking. I'm about 2.5-2.75" above stock height in the front, and maybe 1.5" or so above stock height in the rear. She sits pretty level right now, but I want to restore a tiny bit of rake to help with the gas mileage.
Rather than installing an even taller shackle, I've decided that an Add-A-Leaf is the way to go, which will also stiffen up the rear end just a tiny bit, so it doesn't sag as bad under a load. I've seen the damage caused by the tiny AAL springs (cracked leafs, etc), so I shopped carefully and acquired a Calmini AAL from another user here on the forum. I've always been a fan of this particular setup, because the long springs distribute the weight over the whole current leaf and don't make the ride as harsh or put too much pressure on a single point.
Now I'm down to the questions - for starters, I'm wondring if I should install just one of the leafs per side, or both. The package comes with a long leaf and a shorter leaf. The calmini website says the full package will add roughly 1.5" of height, which is more than I'm looking to get here. I would like to add about .75 or 1 inch total (insert rimshot or "that's what she said" comment here). I could install just one of the two springs per side, or I could install both and remove the factory overload spring. Does anyone have an opinion on any of these options, and if I do install just one of the two, should I go with the longer one higher up in the pack or the shorter one lower down in the pack?
Second - I need some harware to make it all happen. I don't have much experience dealing with leaf springs, especially adding springs to the existing pack. The u-bolts are pretty self explanitory, and I've already found the info I need regarding specs on those. The questions that reamin are:
1) Do I need a pinion angle shim for the axle? I'm only looking to add 1 inch of lift maximum from the additional spring(s), but remember that I already have about 1.5" in the rear from a shackle.
2) Can I reuse the factory center-bolt for the leaf pack, or do I need to replace this (and if I need to replace, what are the specs I need to buy)?
3) How do I remove the existing "clamps" that are keeping the springs alligned toward the ends - I searched and searched both this formum and thenewx for a how-to in regards to adding a leaf, but came up short
4) What should I replace the "clamps" that are keeping the springs alligned with? Some people have mentioned just bolting a couple of steel plates together around the springs - is this ok, or is there a better solution?
5) The factory springs seem to have a small plastic shim installed between each one. I presume this is to prevent the aweful metal on metal squeeking that would occur when the springs flex. The Calmini springs don't have anything like that installed on them - should I try to insert some tiny plastic to shim it out and keep it from squeeking?
Thanks for all of the help everyone!

Did a little deeper dive into the search function over on thenewx...found this for you Joe:
AAL Info and U-Bolt Questions (http://www.thenewx.org/forum/showthread.php?t=107209&highlight=aal+install)
Toro and knightrider should also have some great info as well.
IME...all off road suspension squeaks at some point. Dust gets in between stuff, and greasing all the leaves is an option, but only works so long or until they get dunked through several stream crossings.
Using a set of adjustable shackles helps as well, as you can adjust up as all leaves will settle out after a period of time. My Alcans settled out about 4 months after their install, and I just jumped the PRG adjustable shackles one bolt hole down.
You don't typically need shims until you start to approach 3-3.5" of lift in the rear, and this is done to maintain pinion/driveshaft angles to avoid driveline vibrations. I ran adjustable shackles on the last bolt holes with my 2" PRG PML without any issues.
I'm not sure what type of center bolt is used...anyone?
-
Thanks John. Good info in that thread. I emailed Calmini and can get all of the original hardware for prices that aren't astronomical, but I'd like to avoid spending money on anything I won't need.
They only want a few bucks for the center bolts and $25 for the u-bolt set, so those are a no-brainer. But they want another $30 for the shims and another $25 for the extended bumpstops. These are the two items I'm on the fence about.
I presume the extended bumpstops are to prevent the leafs from overextending and bending backward? With the existing shackle and the other inch or so I'm looking to get out of the added leafs, I could be getting to a point where I need these. I wonder if I could/should shim my factory bumpstops enough with some metal plates to take care of that? The axle shims are still a question mark at this point as well - I guess the biggest question is will it HURT or HELP in any way to add them or not add them? I would hate to avoid spending the $30 and then decide I need them.
I'll wait for Toro or Knightrider to chime in with their thoughts before I place any orders.
-
Joe...I doubt you need bumpstop extensions or mods of any kind there with your lift. You should be fine with stock on a 1.5-2" lift.
Swing by Nisstec's and PRG's websites for more U-bolt/center bolt resources.
-
OK let me see if I can fill the gaps. Center bolts are "special" as the head is round so I would get them from calmini, ubolts are one time use so they need to be replaced as well. I would use both AAL, they are used, so you won't get the full quoted lift. Do you have fixed shackles?
Shims, get them, better to install them than not and have to later. You will know if you need them as you will get vibrations at speed.
Bumpstop extensions can be made out of simple square tubing if you need them, if your shocks bottom out before your bumpstops hit then you need extensions, if you haven't changed the shocks, this won't have changed.
The clamps on the stock leaf can be bent out of the way to allow the new leaf to be inserted and bent back in to place, they are more of just keeping everything in line until the ubolts are tight, no real purpose once everything is tightened up.
The plastic shims are to keep things quiet but as john said, they will make noise, regular maintenance involves spreading the leaf pack and cleaning out the dirt and reapplying grease, the plastic shims on the factory leaf don't even work 100% to eliminate noise. The factory leaf have holes to keep the little spacers, if you try to add some, they will work themselves out, best to just not worry about it and grease them up regularly.

Thanks for all of the great info Jordan. I did look at the PRG and Nisstec options for U-Bolts, and they're all basically in the $25-$30 range. I'll just order them from Calmini as well to save the shipping costs. And good point about the springs already being less than the advertised lift, since they're used. The shackles I have ARE a fixed height, so worst case scenerio, I can order adjustable ones and drop them down if I'm stink-bugging too much after the install. I'm sure they'll sag more over time anyway, so the adjustable ones would allow me to correct that when it happens.
I'll forego the bumpstops and save the $30 on those. I don't think I'll bottom out the shocks by adding another inch at this point.
In my searching, I found a post from Toro where he was saying to use a sliced up bicycle inner-tube to help with some of the noise, in addition to using lithium grease.

I'm down the street from Deaver, so if you need shims or ubolts I could pick them up for you and bring them to Duffman's house this weekend (if he'll have us)
-
Sounds good Steve! That might be a better option than ordering from Calmini anyway. I'll reach out to Deaver tomorrow and see how much they want for everything. I'll need the shims, center bolts and u-bolts. I can probably just pay them over the phone and have you pick it all up. I'll let you know what they say.

Yeah, whatever works best.
When you call, ask for Jeff. Then mention Steve with the red xterra. Might get you a better price - or a higher one :D
-
Haha, will do Steve!
Jordan - I forgot to ask one more thing - what are your thoughts on the stock overload spring? Should I remove it when adding the extra leafs, or should I leave it in place? My understanding is that it won't impact the ride height anymore than the physical thickness of the spring, but how does it impact ride quality? I never tow, but from time to time I'll have a couple of big people in the back seats and maybe some heavy camping gear piled in the back. Might one day end up with a rear tire carrier as well. That being said, this rig is my DD and comfort is pretty important.

Hey Joe,
Most guys toss the stock flat leaf with Calamis but I will bow to Jordan on this, as in most things.
How cool are all these guys? Well done.
Most important is imported lager and domestic cookies ;)
-
stock overload does nothing to ride height because the leaf is below the axle. most people ditch it, but it can help, although not very much, for those times your are heavily loaded. the xterra springs are so under sprung that an AAL just brings the spring rates up to where it should have been from the factory.
imo OME, Deaver or Alcan are the best options, OME being the most economical, but not custom. Deaver and Alcan, while more expensive, will get you the exact ride empty and loaded down you want as long as you get them built to the correct weight.
-
Don't forget to "loosen up" a little and remove your rear sway bar. ;)

Thanks again Jordan. I'll probably just leave the overload spring there for now. As long as it doesn't do anything ot the ride quality until I'm heavily loaded down, then I don't see much of a reason to get rid of it.
Duff - I'll see you this weekend! I will be equipped with imported lager and cookies. Shocktop ok again this time, or do you have a new preference?
And John, the sway bar came off last time I made it over to Duff's house to install the spacers and shackles. These guys have a way of forcing your hand a little - something about "all the cool kids are doing it." ;D
-
I sent you a PM Steve. Everything is good to go with Deaver. Just paid them over the phone and told them to expect you sometime between now and Friday to pick it all up. U bolts, center bolts and axle shims. Thanks again!

For what it's worth, when Greg from PRG installed the lift on my 2005 Xterra (AAL in the back, Total Chaos UCA and RadFlo in the front) he took out the overload leaf, saying it was not needed. In my case we did not change shackles or shocks, or bolts or anything else for that matter. All we (he) did was put in the TC UCAs and the RadFlo coilovers in the front, popped the 2-leaf AAL into the back, removed the overload leafs and the rear sway bar, did an alignment with a crescent wrench and a tape measure, and called it a day. No shims needed (but I do realize that is not always the case), and I did have a set of the factory OR Bilsteins that someone had given me already in place. That alignment lasted for well over 7 years, and the truck road and handled really well. Way better than stock, way better than my new 2014 Pro-4X. All that said, if I were doing it again I would replace all the bolts with new ones. My truck only had about 10,000 miles on at the time.

Dear Joe,
A note from the 'Beer Dictionary':
Shock Top[edit]
Brewed by Anheuser-Busch, Shock Top is a 5.2% abv Belgian-style wheat ale introduced under the name Spring Heat Spiced Wheat brewed in Fort Collins, Colorado as a seasonal beer in 2006, then all year from 2007.[12][13] The beer is brewed with wheat malt, two-row barley, orange, lemon, lime peel, coriander and Cascade and Willamette hops.
This is neither a lager nor an import, unless you concider Colorado a sovereign state. But then Coors would still suck!
Stella Artois /ˈstɛlə ɑrˈtwɑː/, informally called Stella, is a pilsner beer(see pilsner) of between 4.8 and 5.2% ABV. It has been brewed in Leuven, Belgium, since 1926,
Pilsner (also pilsener, pilsen or simply pils) is a type of pale lager. It takes its name from the city of Plzeň, Bohemia, Czech Republic, where it was first produced in 1842.[1] The original Pilsner Urquell beer is still produced there today.
Pilsners are fancy lagers.
Cookies should be delicious and chewy but not too crumbly.
I glad that you got all your parts lined up, Steve's the best. And he'll be the first to tell you that I love to abuse the modders. Nothing's for free ;D
I look forward to seeing you all Saturday!
-
Pardon my lack of knowledge in the world of beer. Feel free to drop your jaw to the floor, but I'm typically a bud light guy myself. Stella it is, I'll come equipped. As for cookies - we'll have to settle for what Costco has to offer, unless my local Stater Brothers has a nice batch of fresh baked chocolate chip ready to go. They're usually quite a bit softer and chewier than the Costco variety, which also aren't too crumbly by the way. :D
And I do recall the jovular ball busting that took place last time I came over. It was a great introduction to some of the gang, and made me realize how great of a group of people you all are. In fact, I'm surprised I didn't get more grief from you when I forgot to remove the 6th lug on one of my wheels and was kicking the crap out of it thinking it was simply stuck on the hub. I guess you were taking it easy on me since I was the new guy. ;D I'm well prepared for more of the same this weekend. See you on Saturday!

Sorry to hear about the Bud Light affliction.
Any cookies are fine, just bustin'.
Good times ahead.
