Ok so i got lots of rear end sag in my 1994 xcab 4x4 and i'm not sure the best fix for the job. I want to lift it about 4" or so front and rear should i put new longer shackles to get the lift i want or blocks? I figured i could just adjust the torsion bars to get the lift i want in front for now... In the end i want a SAS but $$ is going into motor first then suspension. Thanks

 

wash your mouth out foo!!! "blocks" are a nono around here..


only if you just SASed your rig and are stock in the back.. and you need to drive it.. then and maybe only then .. blocks are 'alright'

 

What about add-a-leafs?

 

those dont force axle wrap.. but it stiffens up your ride bigtime.. another simple temporary lift solution..

 

I did not do a SAS on it yet still not sure what to do... Thought about add a leaf just to get the sag out, but then i saw 5" shackle on Davezoffroad.com thought that might gice me what i'm lookin for.

 

Thanks eighty no blocks i promise lol

 

i went with longer shackles in the rear and add a leafs... gotta drop the carrier bearing for the rear driveline. dont forget longer shocks for the rear.

 

Ok Vital so i need to shim the carrier bearing and put longer shackle on the rear of each leaf? Just want to make sure i understand you...

 

I used some 3.5" longer shackles from WabFab to fix the sag on the rear of my 91 PU

works great, and now I'm maybe .75" over stock








What EVER you do, don't use those cheapo AutoZone shackels

talk about a floppy setup...

 

Lol never would i trust autozone with such an important piece of my truck. Do i need longer shackles for the rear on each leaf or same size all around?

 

I heard that Saddam as he was being led to the gallows, was asked, Death bye hanging or lift blocks on an sas's'd 1989 yota, mmmm we know what he picked.

 

just like superbleeder did.. replace the factory shackle with a longer one that is braced in the middle and NOT A CHEAP UNIVERSAL WILL KILL YOU LATER shackel. I also got add a leafs in the rear to help the tired old springs.

 

Cool that settles that shackles it is.. Anyone know how high you can adjust the stock torsion bars?

 

About an inch or two..
You'll regret it though, from what i understand you actually lose articulation on the A-Arms, and the ride is stiffer.
You would probably be better off just with the shackles to even it out...
If you really want to lift it, and get more A-arm travel, get balljoint spacers. That seems to be the most effective way to lift these trucks two inches or so.

 

you can get n inch r 2 with BJS, but short of a lift yer limited.

 

Umm... blocks or extended shackles to lift the rear... serious?
NEITHER!

3 things:
1) You're sagging in the rear so your existing springs are already fatigued to the point they cannot carry the weight they used to be.
2) Blocks will give you lift but will not affect the springs- meaning that you will sit higher but your rear will not be able to compress any more with the blocks than without the blocks: spring is still the same distance from the bump stop.
3) Extended shackles will give you lift and will increase the distance between the spring and the bump stop but the basic rule of thumb is for every inch the shackle bolt-to-bolt length is longer than stock, the vehicle will raise ~1/2 of that. So if you want 4" lift in the rear over what you have now, you're going to need a shackle ~8" longer than stock... and that is assuming your shackle is at 30/45 degrees inclined towards the rear from vertical (not likely at all if your springs are already sagging). If your springs are already sagging, you existing shackles are probably closer to 50-60 degrees from vertical so you'll have to have shackles nearly 6" longer than stock just to get back to stock height and about 10" longer than that to get 4" lift.

 

Ok so what i get from what your saying is i need new springs and shackle if i want? Man i love this site it inspires me to just work on my truck 24/7.!! thanks man

 

I'm gonna have to go with abecadarian on this one.
New springs would for sure be the way to go.

 

ohhh i gotta put it in there!! FORD SPRINGS haha, well thats what im gonna do, their alot cheaper than replacement springs or OME springs and they flex very good from my understanding, you just have to move the front hanger forward it think it was 11"?? and an 8" shackle to match my front lift..if you search you can find the exact thread on it if you wanna go that route

 

Ford springs are cheaper than replacements? So you can get the springs, 2 hangars and 2 shackles for 220 bucks? That's what it cost me for new 4-5" lift springs and u-bolts for the rear on my 88 4Runner.
