I was just reading on how to do the cheap lift by extending the rear shackles (which i found quite helpful) but just wondering on how to lift the front also? Im new to doing anything myself on my car,im just sick of the same old `its an import so we charge you double` thing from places.can someone tell me the procedure for lifting the front so it sits level? cheers

JJ, I fully agree with gevees there, by the time you get it right you could have done a sas and be away laughing!!!

Clarkside,
It is very easy, all you need is a can of CRC or WD40, a 27?MM spanner/socket a jack, and an hour or so.

1, A day or 2 before hop under neath your truck and find the mount that links the torsion bar to the chassis, there is a bolt head there (27?mm, see photo, its on the left of the photo), spray that bolt with the CRC/WD40 and let it soak. You don't have to do this but it makes it easier.
2, Jack one front wheel at a time and screw the bolt in a couple of turns at a time, repeat on the other side. Then take your truck for a drive around the block to let the torsion bars settle. It is advised to unbolt one end of your sway bar whilst doing this, as it can have an affect.

3, Repeat step 2 untill you get the desired height you want, and re-attach the sway bar. Just remember that if your "A" arm can't reach the top bump stop when fully compressed then you are losing travel.

clarkside, what mulover is telling you is torsion bar cranking/winding. torsion bar is the main load baring spring of most IFS systems. it is similar to coil springs, but contrary to coil springs, it twists as you hit a bump, rather than a coil, compressing. my thread at the old forum: http://clubisuzu.proboards.com/index.cg ... hread=3589 it helps. and yes it was the time that i still know nothing :D :lol: :)

you might consider doing a ball-joint flip afterwards because after you wind the torsion bars, you loose the travel which gives you a harsh ride. when you wind it to the max there is no downtravel left so its just like you dont have any suspension :D balljoint flip is relocating your balljoint from the top of its slot to the bottom. it gives additional travel. also trimming the bumpstop gives you additional travel because this acts as a stopper. just read on :)

do you wind until the front wheels have the same wheelarch to rim measurement as the rear, or so you add 1.5in(if thats the size lift your doing) to the overall measurement?

either or, but i generally do it to what ever looks good, i like the front of my truck a little lower than the back. Its a matter of personal preference though.

What JJ has said is ture, but if your only lifting it 25-35mm you shouldn't need to worry about a ball joint flip. Do the lift, let it settle for a couple of weeks so you know you are happy with it and then get a wheel alignment. They will tell you if you need to do anything further.

ive noticed the front is already higher than the back like i have something heavy in the boot,the roof slopes backwards so i think i just have to fugure out the difference in height then just extend the rear shackles to level it out.
Thanks a lot for the advice guys you have probably just saved me a few hundred dollars in some bloke ripping me off on a small job,plus im a boilermaker so i can fabricate the shackles myself because i seen them on a 4x4 site for $280 a pair.

Hopefully soon I'll post up a Torsion FAQ with mulover pic and description plus some other stuff.

Sounds like your rear leafs have sagged, might be a good idea to get checked and research for a set of new leafs. Again I try and get a FAQ of leaf spring up ASAP,.....but if you desperate search the old forum and you'll heap about both torsion bars and leaf springs.

lol no time, too much to do,..... ;)

^ same as i was thinkin' leaf springs sag. i also think mine is already sagged because when we left the car shop the mechanic told us that the back was lower than the front so he levelled off the torsion bars. hmmm.. :?

If you already have sagging springs then I'd replace the springs with ones that have a 2" lift in them, and see how it sits. If you need more lift after that then extend your hangers to suit.
Its a bigger expense up front but it will be worth it in the long run.

You will probably end up fitting 2 inch lift springs and find you got close to 4 inches being 2 inches to fix the sag and 2 more as the lift

Its not the length of the spring, its the amount of set thats in the spring. If you took your old springs out and compaired them to a new set, the new ones would have alot more curve in them, but the actual length of each leaf will be about the same.

88 - 91 Jackeroo or trooper springs are correct but you dont need the heavy duty version

83-92 Jackaroo ones are very close to the MU springs.
The second and third leaf are a bit longer
If the company list the same springs for a rodeo and jackaroo they will be stiff
Efs seems the only company that lists a different spring
Efs part No HOL-03E

If possible try get a pair with the military wrap. The second leaf wraps part or all the way around the eyes of the first leaf. This makes them less prone to bending
I put a set of EFS ones in my truck and they are pretty good. About $500 i think a couple of years agao.
