can i get an off the shelf 4" body lift?

I assume you have not overlooked the fact that you also will need custom built tie rods (x4) and also the packing spacers for the 4 boot floor supports.

There is a lot of stuff you need to consider when doing a 4" lift apart from the steering rod not being long enough.

For one thing the radiator is going to have to drop 4"!

You will need to replace all the brake flexi hoses. If yours is a manual then you most likely may need to extend the clutch flexi hose as well.

You will have to make some sort of custom extension for the diff lock lever as a 4" drop will mean it will disappear into the floor tunnel. You will probably need to extend the gear lever as well.

Then there is all kinds of stuff connected to the engine and chassis like wiring and earth leads etc that may well need relocating perhaps.

I'm not convinced making bolts from threaded rod is a good idea for this - AFAIK that stuff isn't the right sort of steel. The June issue of Total Off Road has an article about fabrication which included some information on how to pick the right bolts for this sort of thing. I do remember that they need to have a strength rating (marked on the bolt head with raised "dashes" radiating from the centre) but I don't remember how many dashes equated to what strength.

The general advice seemed to be "buy bolts with as many dashes as you can find".  :lol:

wizard:
Dont use threaded rod. Its far to soft.
just to prove it, take a bit of rod 150mm long and bend it by hand in a vice, now do the same with a bolt..

You will battle to find high tensile bolts the lenght you require. You are looking at 225 - 250mm long. I had a hard time getting the 6 inch UNF bolts for the 2 inch body kits listed on e bay. Metric will be easier to come by.
The biggest problem you will have is finding bolts.

The radiator is mounted on the chassis so you will need to lift it a bit to line it up with the grill.
You will need to extend the steering shaft, the gear nad transfer box levers and the fuel filler pipe.
The tie rods and rear floor mounts are easy enough (i can supply these)as well as the body spacers if you like.

Good luck

wizard :twisted:

Disco Matt:
Right, I've got the article in front of me which I didn't have earlier. For SAE bolts the markings are as follows:

Grade 5 has three markings

Grade 8 has six markings

and apparently you should only use grade five or above on vehicles. Metric hardware apparently has an equivelent system where the strength is stamped on the head of the bolt as a number (they quote 8.8, 10.9 and 12.9 as common ones).

thanks for the input i didnt mention the other bits as they are somthing i can over come as i will be doing it in a fully kitted out workshop with plenty of steel laying about and a 250amp welder to play with however as its a workshop for plant there is no ramp so i will use a digger to lift the body.

cheers for the offer wizard i should have some spacers coming today fingers crossed as for the floor spacers i dont think i need them as i have welded a frame in the boot and made a steel floor that is rivited and sealed to the frame however one of the new crossmembers i made was welded to the body and the chassis not such a good idea :oops:

the tie rods: i was hoping i could make some up or extend the originals

the wiring: have plenty of wire and cables laying about so fingers crossed i should be ok

gear and hi/low stick: this may cause me problems with the extra amount of throw they will have but i will suck it and see

filler neck: what is the id of the pipe i may need to find somthing to extend it as i dont think i could just put a longer peice of pipe in as there is quite a bend in the original again could be wrong

clutch flexi: pirtek or simlar local cheaper option

radiator/intercooler: unsure how much movement they have so will see what i can do

steering colum: again unsure but will have somthing kicking about that i can use

bolts: still unsure but maybee some headbolts of some sort as ive seen some monster long ones (just an idea)
does any body know how much you can drill out of a body mount bush as it might be easier to find a fatter bolt in the lenth required?
