Sweet, Coops! Did it bring it up decent? You like how they ride? Mine don't bounce at all and gave me a much better ride.

Take care, Coops,

Mark

 

ride is good and yes it did bring the back end up

 

cool coops.....did you go with the 12" x 125...or the 14 x 100?

 

Sorry if this has been asked (I already search, couldn't find anything). How does this mod compare to Add-A-Leaf? I was planning on installing a leaf this weekend, but I might do this instead. Not looking for too much lift, just want to keep my butt from dragging.

 

I'm by no means an expert on this, and I'm not even sure if it's correct.... but I've heard from more than one person that their flex decreased with an AAL, compared to the Zuk mod.

The man to really press on that, posted right above you, Dr. Reddog, lol... Zuk would most likely know. I love my coils, ....but it goes without saying that, 'it's not for everyone'.

 

12 x 125

 

By nature an AAL will stiffen your springs and limit suspension travel. Only way I can see the Zuk mod limiting travel is at full compression if the gaps in the coils close enough for the coils to start touching.

 

In that case, I think I'll go with the mod. I have 2 sets of speed bumps near my place that have been rather spine jarring lately. It seems like AAL wouldn't help with this.

 

No, an AAL will not help you going over speed bumps. They will however increase load carrying ablity & give a little lift. Maybe the Zuk would be the best option for you.

 

There's almost no comparison....the right coil will give a SOFTER ride, probably won't settle much for 10 years, it will give better payload, and appear to make better use of the wheel travel. This is especially true for the Runners that have the leafpack firmly settled down on the super thick overload as that results in the most buckboard ride possible.
It works more effectively, in my opinion, for the Runners due to the leafs being closer to the frame. Your 84 pick-up has a larger gap and maybe the 14 x 100 will work....get the tape measure out and shoot me the distance from bottom of frame to the surface to top of leafpack.
This mod works super on speed bumps....especially with Bilsteins. I know because I have 14 x 100's on my 01 Taco with the bils... it loves speed bumps. I set my cruise for 30 and just go over them....relatively smoothly at that.

 

I am guilty of having no guard on my hand-grinder.....I do use a clear fullface shield and gloves (and ear-muffs)for sure
....so if you use a grinder to take off the upper steel 'deflecters' then use care. see below what happened to a 'not too smart' fellow that did it all wrong...he removed the guard and somehow secured a 12" cutting wheel on a 7" grinder....that is a hell of a lot of spinning momentum there at 10,000 rpm...

 

OMGOSHHHHHHHHHH! That is TERRIBLE REGARDING THAT GUY!

Pertaining to the info you're shooting in here, ...THANKS, ZUK! I'm just a customer, and I MAINLY post extensively informative threads to try and help people 'think' about 'what's next', etc. I mean, it's 'THOSE' threads that have helped me, so much, so far, ya know? So who better to have on here than the guy who inspired this mod on the First Gens, eh? lol...

Thanks!

 

Distance from bottom of frame to top of leaf pack is 9"
Distance from rim to fender is 10.5"

How much settle is there with the 14 x100? I have a stock front end and don't want much more than 1" rake.

 

Zuk will know, Dr.....

As for my 4runner, I had 10" on the dot in the rear, and it brought me up to 13" on the dot, (top of rim to top of well). That gave me around 1.5" of rake, I suppose, as I'm 13", maybe 13.25" in the front(top to top).....(Zuk, ...isn't factory Front end on 4runners 1.5" taller(wheel top to well top) than the rear?

 

Reddog----Logic says that all coils have to settle some. For some reason, leafpacks really, really settle more than they should but I digress)....but, in the case of coils that share the load about 50/50 with the leafs, I would say you won't see any settling. I'd go with the 14 x 100. That should result in 2.5 to 3" lift. If it stinkbugs too much then cut the coils 2 inches shorter and all is good. Better to have a little too much lift and have the option of coil cutting. Besides, the 100 poundage rate is as soft as it gets.

ChefYota4x4-- You're doing a fine job with informing the guys about the ZUK mod. You know exactly how well they work on stock type Runners and such.....so keep up the good work

The Runners have a larger looking wheelwell in the front....which screws up the lines along the side. When the rig is setting perfectly level, the rear looks like it's sagging some because the rear tire looks more stuffed in the well than the front is. I like some rake to even out the wheelwell look for that reason.

 

Thanks ZUK! I think I will go with the 14". I'll let you know how it goes.

 

Great It's also ok to post some before and after pics. ( www.photobucket.com ) We'll let you know if it has too much rake

ps--Will your shocks will tolerate the new 3" lift without topping out too much?

 

That's one reason I don't want too much lift, because I'm honestly not sure. I'm going to put it up on jack stands and see if I can tell how much lift the shocks allow. I assume it should be okay since I'm just trying to restore height plus a little. My leaf stack is pretty squashed as is.

 

Is the rear squat a factory design or due to the springs slowly dying?

 

Hey Sean,.....

I believe it's mainly due to the length-and-strength of the springs in relation to the MUCH higher weight in the rear on the 4runners. My buddy has a pick up with stock springs and it's the same year.... no sag. I believe there are other issues involved with possibly different hardware, but I'll let ZUk answer that, ... and in fact, if you read up a bit?... I think he already did... can't be sure and don't have time to check... check it out though, Sean,...think it's up there^^ lol.

Have a good'n!

Mark
