the totoal chaos kit should give around 4" of lift

 

Not bad. A diff drop might not be needed afterall, depending on how high he wants to go.

 

the reason i want 5" in the rear is to take care of the rear sag so the rig will actually sit level.
Thanks

 

Remember, 5in is not measured when it is sagging, it's measured when it's level. My 1.5in downey HDs lifted the rear 1.5in higher than the stock front.

here is a custom set up.

 

That is one sick 2nd gen!! I wonder if he still has that here in San Diego--I would like to see it.

 

the total chaos kit doesnt use or need a drop diff. to retain 4wd capability you must limit travel to 12" unless you use porche cv's. the kit in its stock form uses T100 axleshafts which are longer and have more travel.

keep in mind also with this kit your front track is going to be wider than the rear.

 

Is there any drawbacks to the track differences?

 

not really, it will look kinda funny:

(not a total chaos kit shown, but nearly identical)

you will just have to compensate for the difference when negotiating an obstacle.

you could swap in a T100 rear axle ~66" wide, or a taco axle ~62" wide with some spacers, the 3rds are stronger but have downsides of their own

EDIT: the stock axle is ~59" wide and the TC a-arms are 3 inches longer on each side than stock, which gives ~2.5" of additional width at ride height

 

I am curious about actual lift yielded by the kits.

Back in the day, those running this kit on ODW mentioned no real lift, except if you cranked the torsion bars. Perhaps Brian will come in, or I will get motivated and search for Hersh's old posts.

I personally am having a hard time seeing how it would net lift since all you are doing is adding longer arms.

 

i still have the lift kit brian has. WCOR, which has been dead a a while now...

built into the kit is a mild 1-2" lift. now, you can also crank the t-bars, and get even more lift.

since i decided to have a mild lift on my truck, 1.2 to 2" all the way around, i am only running 32's... but that was enough to get my by on the dusy trail. now with the addition of dual cases, i am better than before. my plans before the all pro jambo is get a 3" all the way around. yeah, it's not that much, but i'm not really into rocks, but i wont shy away from them...

track is wider by 2" on each side by the use of a longer custom axle, lubro (porsche) inner joint and oem outer joint.

kit is very simple in design.

if you widen the axle, or make the axle longer, the longer the arc is, therefore greater travel. no magic there.

ride was incredible when i got it. came with the custom valved bilstens that downey sold in their catalog.

before the kit, there was dip in the freeway that when i had my old OEM setup with rancho 9000 shocks, i could always feel.

coming home, that first nite, i drove over that same spot, i coulda sworn they filled in that hole...

now, a good 6-7 years later, the bilsteins needs replacing. but it's still not as bad as my previous setup...

 

this is the earliest i heard of the WCOR kit:

http://www.off-road.com/toyota/features/desertrat/

people i've known who had the WCOR:

mike hershauer
brian m. (brian's 4x4 site)
another guy who is local to me... forgot his name though... deo f. was his name...


brian and the deo both broke the upper arm on theirs. brian went sas. deo went and got his a-arm fix.

btw, brian bought hersh's kit...

so that's a little history of WCOR...

 

so there isnt a diffdrop made into the chaos kit is there? isnt that how most of the 4" lifts are made out there, with a 4" diffdroop?
Thanks

 

trailmaster, procomp, and maybe a couple more, all get their IFS lift by dropping the entire IFS structure. no increase in travel, maybe an inch or two.

WCOR, chaos and others are not really made for rock crawling. their travel is there for jumping and prerunning.

you wouldnt believe how plush the WCOR kit is running 50-60 mph on fire roads.

btw, as a history note, rockstomper also made a similar kit to WCOR, et al, but his was much sturdier for rockcrawling.

 

That is mainly why i am wanting to stay with the IFS, fireroads. alot of my offroading is when i am hunting, on my construction sites, ect. i think that a sloid axle would just make the ride worse for that kind of offroading, although there are some times while hunting i wish i had a solid axle.
EDIT: that and i think coilovers would just be schaweet

 

its all in the geometry dude. lets say, that the a-arms reside at a 60 degree angle. for every inch you add to the a-arm, it will hang down 2 inches lower. so a 3-inch longer arm will net 6 inches of lift. the arms arent quite that steep, but you get the idea.

 

Um, check your math, that's not even close.

 

whoops

i was a little tired last night and had my 30-60-90 triangle all fudged up in my head.

if you have a 3 inch longer a-arm at a 60 degree angle, you will get 5.2" of additional lift

 

Uh, no, um...

Your hypotonus is the A-arm. I'm not sure how long the stock A-arm is, but lets say it is 12 inches long and the angle we're using is 30deg (the complement of your 60, so same thing).

Opposite/hyp=sin30.

Opp=12" x sin30
Opp=12" x 0.5
Opp=6" = stock height

Add 3 inches

Opp=15" x 0.5
Opp=7.5" = new height

A lift of 1.5inches

Think of it this way: The most lift you're going to get is if the A-arm is angled straight down into the ground. If you lengthen the A-arm 1inch you'll get a 1inch lift. You can never gain more lift than the amount you lengthen the A-arm.

 

actually, we were both wrong
use the law of cosines

2.59" of lift, 1.5" of extra track width

if the arm was at a 30 degree angle, it would have 1.5" of lift and 2.59" of extra track width
