The Lokka was fantastic. I found myself getting a bit lazy on the some of the moderate lines early in the week, I could take whatever line I wanted. On Kane Creek and a few others it was a godsend.

I think the 2 best choices for the X are 180/75 and 255/70. I did 180/75. I was running the OME HD leafs and when I talked to PRG Greg. With the stiff spring packs he reccomended the softer valving.

I felt severly limited in the articulation with the 8" travel (0-3" lift) Radflos and the OME HD leafs. I ended up taking the extra leaf off, making it the OME MD leaf pack, and installing 2" lift shackles. It's a little soft now but it flexes great. With the 2" lift shackles the overload leafs are kicking in before I bottom out so it takes bumps at speed like a champ. Its a little squishier than I'd like on sharp highway corners, but I think that has a lot to do with the lift height. I might reinstall the extra leaf to get a little more lift and see how well it stuffs and how the ride feels with softer valving.

I'm currently only getting about 9.5" of travel shaft showing at full droop (one side stuffed, it might be different with both sides drooped). I think that there could be more available with Alcan or Deaver springs. If theres a big advantage with those I might have to change out the springs. Otherwise I'll install revolver shackles and a center limit strap. That will limit straight droop but allow additional articulation.

For now I happy with the performance of the setup, but I know there is room for improvment.

That is awesome. I cant wait to get the front R180 Air locker. It will be fun to see the capability of the X locked front and rear for me.

So if i'm eventually going to run Alcan springs for 3.5-4" lift and 350+lbs should i choose the softer setting of 180/75?

If i custom mounted and stuffed 12" shocks in the rear is there anyway to get full travel out of them with the alcans and prg shackles?

Are revolver shackles the same as creeper shackles?

Sounds like you might have a similar setup to what I'll have in the rear, I'll let you know how it works out once I get the shocks relocated here in the next two weeks or so. Something to consider could be the 12" travel short body shocks that Nick is running.

(Oh, and I have the locker in the diff ready to go... along with your trail spare cv's if you want ;)) haha

Whats the difference between 12" travel short body and 12" travel standard/remote resi shocks?

Stop pressuring me! Jk lol I need to save some money up again. Moab put a dent in my bank.

I don't know. Depends on what kind of ride you want. I'm really not educated enough to feel like I can offer a good answer. So instead of :pukeright:misinformation I'll remain silent.

If i custom mounted and stuffed 12" shocks in the rear is there anyway to get full travel out of them with the alcans and prg shackles?
Maybe. I know PRG Greg is reporting 11.5" rear travel with custom 2.5" Emulsion 12" travel Radflos and custom springs. I don't know where he's mounting them though.

Honestly, without a pretty unique setup the 10" 7100s in the stock mounting locations would be ideal. I think you'd get full compression and full droop of most springs. You would need to address a couple things like the remote reservoir hose interfering with the body and different size lower mount bolts but you could fit them with minimal modifications. You might even try asking if they'll make them with 90 degree fittings coming out of the shock body and then be able to mount them in the stock locations and only have to change the lower bolts size.

Are revolver shackles the same as creeper shackles?
No.
Creeper shackles allow some rotation of the springs in the mounting points to relieve the stress of the axle twisting them in the middle. The spring will also resist articulation to some degree by acting as a torsion spring when severely flexed.
Advantages: Relieved stress in leaf springs, less likely to fail. Greater articulation (marginally I imagine).
Disadvantages:
The leaf springs hold the weight of the vehicle and also hold the axle in place. You loose some of the side to side rigidity of rear axle. Its worse if the joint is installed in the frame side of the shackle. That is a bad design. It should be on the spring end of the shackle. You could also only install on one end of the spring, probably best in the rear (shackle) side.

They are important when you start getting a lot of articulation. I've been looking at these for my solution:
http://www.deaverspring.com/products/bushings.html
I believe we'd need part number SBA2041 for the Xterra.

Revolver shackles unfold to allow the more droop. The weight of the vehicle holds them "folded" and they act like normal shackles under normal conditions. Once the spring reaches full extension the shackle starts to unfold, allowing the spring and consequently the axle to droop further. They also have a joint allowing the back end of the spring to twist, giving exactly the same advantage (to the rear of the spring) as having a "creeper shackle" or "baja bushing."

The arguments against this is that without the spring force acting on the wheel there will be no actual traction or balance gained from the wheel on the ground. Many claim they are only good for showing off on ramps, not for real applications.

I disagree with this assessment. With a normal shackle after the spring is fully extended and the wheel will start to lift because you can't pull the spring down. With a revolver shackle the drooped side is allowed to fall further. There is a force pushing that wheel down. Obviously the weight of the wheel tire and axle. Also, and more importantly, the stuffed wheel is pushing up on the axle and the stuffed spring is pushing down on the axle. Those forces are not in the same line, so they create a teeter-totter action (moment couple). The stuffed spring acts as the fulcrum and the stuffed wheel's force gets transferred to the drooping wheel. Like anything else there are limits, but there are advantages to be gained.

The disadvantage is they "unload" on steep downhills. The release of the weight of the axle when your a$$ is in the air causes the vehicle to lurch towards its nose. Apparently this can be unnerving for the driver and/or passengers/bystanders/etc.

The solution is a limit strap attached to the center of the axle set at just about the point where the shackles will start to unfold. This will prevent the "unloading" but allow one wheel to droop further if the other wheel is stuffed.

That's ALL theory and hearsay I've gathered from the internets, run through my mechanical engineering BS filter and regurgitated to you.

Length:

Standard
Travel 12"
Extended Length 31.10"
Collapsed Length 19.53"
VS.
Short Body
Travel 12"
Extended Length 27.68"
Collapsed Length 16.10"

A shorter body allows you to fit a longer travel shock into a smaller space. Right now Xkid is running 12" travel "standard body" Radflos in the stock mounting locations. Ask him about his up travel... :crybaby:

To properly run those shocks he is going to have to do some major work moving those up or install bump stop extensions and sacrifice the fully stuffed position. Ask KaiOtiK (the guy who bent his frame on Hell's Gate... Andy??) about bump stop extensions.

What up travel? haha

As for the shock relocation...There's a lot of room to move the mounts up... 6 3/4" to be exact. I'll probably move them up 6 1/4- 6 1/2" given I won't already be absolutely fully stuffed or at full droop. In that case I'll measure where I'll be fully stuffed or at full droop and go from there. It might take a bit of measuring but I'm definitely going to get as out them as physically possible. When it's finished I should have a pretty decent amount of travel in the rear.
