Tried to search for some info on this with no luck.

I'm just trying to get some info on lifting an IFS truck. In the national code of practice for vehicle modifications it says, "When raising a vehicle the original rebound travel amount must be maintained. The rebound shall be limited by the same method as the manufacturer. For example, limit straps or shock absorber full extension." As we all know, when you lift an ifs car, downward wheel travel is reduced, so does this mean that it is illegal or is downward travel and rebound travel two different things.

Any help would be great because im confused as hell.

Cheers
Dylan

You can wind torsions or replace struts on IFS vehicles and retain the manufacturer's rebound method. The law states something like "the ride height must remain in the middle third of the suspension stroke". Which is where you want it anyway so it's not a prob to get 30-40mm out of most IFS vehicles without detriment to the geometry.
Trying to do anything more than a minor lift, however is going to stress them badly unless a 'drop' kit like skyjacker is used, which effectively spaces the diff, arms etc., down from the vehicle, thus achieving lift and retaining geometry. They won't get engineered in QLD though, and the rest of the country is soon to follow as well so best to stick with a small lift or get a different vehicle.

To decide if what you want to do is illegal or not, I suggest that you get in touch with the licencing/registration authorities. After all, they are the people who will enfore such modifications. Don't forget to check with your insurance company too.

Cheers, thanks for that.

To be honest I'm not at all concerned about getting caught or defected or anything like that. The insurance side of things is my only worry, so I guess as long as I tell them the car is lifted and they still insure it i'm in the clear.

If you are not concerned if it is legal or not then why ask us.Well that was your initial question.

To answer the real important part of your post. Paramount in your lifting should be the safety aspect. What could happen if it causes an accident. Our IFS is lifted and its legal where we live and we do not even have to declare it to the authorities. That in itself tells me its safe. It lifted because we fitted special shocks and springs. A byproduct - not an initial aim.

The last thing you should worry about is whether your insurance company will accept the mod. That depends on what is stated in your contract/agreement. We cannot answer that. You should contact them.

Bit rough aren't I!. Your statement about not caring about it being legal or not rubbed me a bit the wrong way. It was an illegally modified car that rolled and destroyed my brothers future. 15 years pain before he died. Its a very personal and soft point with me.

Because if it is illegal then insurance wont cover it or wont pay a claim when they find out it is illegal!!!!!!!!!

bit rough and a bit ignorant. I am very sorry about your brother but at no point did I say that I didn't care about the safety aspect. Many things that are considered illegal are perfectly safe. Like in qld you are not allowed to put tyres with a rolling diameter more than 15mm bigger than standard. That means almost every 4wd on the road in qld with aftermarket tyres is illegal but still safe. Get your s**t together before you have a go at me.

Just because you think it may be safe doesnt make it so.

You asked for advice and were given some and now you dont like it.

If you dont want diiffering opinions dont ask the question.

Okay.

And im only talking about a 50mm lift which is also perfectly safe as and i wouldnt go any bigger for that very reason. Sorry but being negatively judged for no reason is a bit of a sore point with me.

Alright

Its all in how you didnt ask the question.

Had you said "I am thinking of lifting my IFS truck 50mm", Is this legal and/or advisable,
you wouldnt have got the comments.

Only you know what you want to actually do and if you leave out the

important info as above, how do you expect sensible answers.

The members will help but cant read minds.

fair enough????????

Maybe I needed to give a few more details or word my question better but i didnt believe specifics were needed based on my question which was to get peoples interpretations on the wording of the legislation and as to whether downward wheel travel and rebound travel were the same thing or not. And at the end of the day I asked a simple question and was hoping for a simple answer. And as for not liking the advice, everyone else has been helpful, but you didnt give me any advise about the original question. All you did was jump to conclusions and give me advice about something that I didn't ask. Maybe you needed to ask for the extra info in order to give me a sensible answer before you jump down my throat. And I can also appreciate that my comment about not getting caught could be taken the wrong way and I should have worded it better but the only, and I repeat ONLY reason I was not worried about getting caught is because if the 50mm lift were to be illegal that it was my opinion would be rediculous. Half of my family, including my brother, uncle and grandfather are cops so no one is as concerned about following the law as me, but in this instance I was not concerned as I knew what I wanted to do to my truck is safe. And my stance on this was supported by my brother the cop who has his own 4wd with a 2 inch lift. And before any comment is made about the fact that my brother should know the law because he is a cop, he is a cop in qld where the lifts are legal, and my original question relates to the NATIONAL code of practice as I was lead to believe that qld will be implementing this in the new year when I plan to lift my car.

a bit long winded but fair enough???????

Torsion bar front or strut coils.

1. Often on torsion bar front pajeros, wind up the torsion bars for about 30mm and cut the bottom droop stop down by half , gives about 20mm more travel.
Too much and you regularly do in CV joints. So keep checking CV joints.

2. On pajero with torsion bar, I am told you can swap the top ball joint over with the bottom ball joint.
Bit dangerous since top ball joint is captured, and if it goes stays in place, bottom joint at top will result in the top A arm falling away if it goes.
But this gives about 30mm of lift, but you take a real risk and need to check the joints for every trip.
