hi thea im thinking bot putting in extended shackels in my 1992 isuzu mu but im worried abot reacking things wen i lift it up i only wont a 2inch lift and was going to wind up the front torsion bars if i rasie it like this 2inchs will every think be okay like the vcs whont brake or any think also could i just put my rear diff under the leafs and wind up torsions?? one last thing does any1 now wea too get extened shackels from in auckland region or any1 have any for sale

diff under the spring is a massive job which gives about 150mm lift. Certifiers hate them unless its a factory set up.
Lift by shackle or replacement spring of 50mm is simple enough 9 times out of 10 the brake lines and shocks are ok with this lift in the back
In the front winding the torsion bars is correct but at 50mm you should also do a ball joint flip to restore wheel alignment and down travel. It does put more strain on the cv joints so do find and keep some spares

okay sweet thanks wich ball joint do i flip and how do u have any pics off one fliped??

Remember fitting extended shackles makes the vehicle sway more on the road ( well mine does anyway) springs are a better way to lift it and has a nicer ride

the term ball joint flip isnt exactly correct
All it is is unbolt the top ball joint including the taper. Remove. Now the fun part. You will see that it was bolted on in such a way that the taper was through the hole in the A arm. Place the joint under the arm with the taper still pointing down and bolt in place. This does 2 things. First it changes the angle of the A arm allowing more travel Second it effectivly lengthens the A arm. This is nessecsary on the Isuzu as the shim adjustment for camber are behind the bracket and to re align after a left you have to remove shims. At about 50mm you run out and may find it impossible to set camber without this mod.

okay sweet thank you, also wea are the sims located?

You dont need to worry about these as you get them adjusted on a wheel alignment machine at your local tyre shop. If you look at the top A arm you will see its bolted through some bushes to a bracket behind the chassis. The shims are between the bracket and the chassis

okay thanks i will post up how i get along with it gona be a few weeks hahah cheers mate

As a wheel alignment tech I must say... I HATE shim jobs......... lol.

if anyone ever takes the front A arm assembly off be very careful to put all the shims back exactly where they came from Some are long shims across both bolts and some are just across one bolt. The short ones are for caster
