Hey Guys,

Just wondering if anyone has any advice on moving the rear spring on a 1200 ute inward in order to fit a 15x8.5 inch rim inside the guard without modifying it.

The diff has been shortened to accomodate this, and I know the spring mounts on the diff can be moved inwards with ease, but how do you go about getting the chassis shackles across?

I was thinking of using some offset shackles, but I don't think I am going to get enough clearance to run a 26x8.5" slick.

Basically, the plan is to have a mini-tubbed rear end, and I wan's all the rear end mods to be legal and able to be engineered.

Can anyone offer any advice?

Cheers.

the only way is to make new mounts in the desired position and strengthen the floor around them and have all this mount off the original rails so to keep its strength.
You are best to consult an engineer, preferably the one who will finally pass it. Remember moving the springs in is going the have the same effect on handling as it would if you raised the car. All of this the engineer will have to find satisfactory before it will be passes

My question to you is, can you fit the desired rim and tyre inside a bigger tub without having it scrub on the rail during diff movement, all while keeping the tyre within the wheel arch or flare?
If not, just moving the springs in isnt going to help
On my 1000 wagon I drilled out the rails and moved them in. If you dont go to far and keep it looking original, no one will ask any questions at rego time unless you tell them.

yeah i did my bosses this week 50 mm in so that he can run his drag slicks but he wont let me take any pics lol but this long weekend i hope to have a chance to do my own so i will post some picks when i am done , the back hangers are easy the front ones take a fair bit more work good luck with it , i am moving mine because i want to run a 245 40 15 under mine and with the spring in it is real easy that gives u near 280 mm under the gaurd

Hey Guys,

Thanks for the replies.

I know where you're coming from with the chassis rails, but to be honest, I never really gave it much thought!

If possible, I want to avoid moving the chassis rails inwards, purely to avoid having to get it all engineered should the need arise.

I'll have to measure from about 10mm inside the guard to the edge of the chassis rails, but now that you mentioned it, I don't think the rima dntyre is going to fit wihout bottoming on the chassis rail itself. I suppose if I enf up moving th chassis rails inwards, I won't have to worry about moving thespring mounts at all.

phunkdoktaspok, I'm not 100% sure of what I am looking at in your attached picture? Can you explain it to me a little better?

Cheers.

Yeah its just a pic of my wagons drivers side rail with half the shock crossmember and half the wheel tub still attached. Basically just showing the way I drilled it all out and left bits attached so I could move it in the required amount and then just add a strip of metal up the centre of the wheel tub.

wouldn't an easier option be to convert to a 2link setup (semi trailing) off the existing leaf mounts, remove the leaves altogether and run coilovers under the arse end?

if you used 32mm

there's a lot of angles in a "2 link setup".

I suspect it's not as easy as some may lead you to believe.

I know it took a good couple of weeks to get mine looking ok, only time will tell if it's good stuff.

Chris I thought yours was a 4 link setup?
I dont think any setup is easier as all have many contributing factors. ie, handling, suspension travel, pinion angle. etc.
In a 2 link setup what locates the pinions angle? I have only ever seen 2 link setups used with leaf springs to prevent spring windup ( tramping)

I thought he might have been talking about just one side..(4 link total)

I'd agree with you if that's what you think he meant. 2 link = tramp rods.

Ok I get you now.
I still go back to my question of can the chosen wheel tyre combo fit with in the rail and arch without scrubing. In the below pic of a 1200 wagon not ute ( but I am sure it is roughly the same) The center of the rails are offset to the springs but this is still minimal to prevent scrubing. By only moving the springs doesnt increase the wheel tyre size unless only driving in straight lines is the idea.
