coils in hilux

[mattlux]

can anyone help me on what coils you have used and what spring mounts were used or were custom ones needed in front to fit in hilux and any tricks i should know before starting thanks

[outback_lux]

hi i am doing the same to my 86 lux and i got told this... i asked about bundeera diffs and this is what i got



yes they will. but if you are using the bundera steering on the fornt axle then you can't fit a hilux diff as the snout will hit the tierod - you need a high pinion diff in the front.


but i am doing a hilux cross over steer kit and it will all work hope this sort of helps

[beebee]

There is no "easy" way. Any method will involve custom engineering of mounting points etc. The easiest method is to install bundera diffs as previously said. Still requires steering box change though.

Have fun!!

What diameter coils are best used?

I'm sick and tired of trashing front leaf springs so i see the only way out is to do a coil conversion.

GQ diameter coils with standard Hilux diffs is ultra mega super tight. Full compression may lead to the tyre rubbing on the top hat or the coil itself.

For front use Bundera coil hats and Bundera coils OR If you can find them 79 cruiser coil hats and coils.
Yep the Bundera front end set up is the easiest.
If you can find a 79 series front end it is better but good luck finding one.
Both are high pinion.
If you use the HP diff you can retain factory Bundera steering components.
Works out much cheaper than buying cross over steering set up.
You will need an IFS steering box regardless of which set up you use.

Rear best set up is the surf coils , get a rear surf diff housing or 4runner housing as it already has coil mounts and link brackets already welded on.
Can use your diff center and IFS rear axles.Gives you the wide track that Hilux needs.
Use lower 80 series control arms as the surf/4runner are very short.
It helps level out the arms to give a nicer ride .

Have a look at Neil Cooper's Hilux. He has made Coil overs in the front with Rangie arms. Runs his existing steering with IFS Box. Rear uses airbags with rangie front arms also.

can you use the front diff & brackets arms etc off a 80 to put in a ifs 4 runner it allready has the coil rear end

[killalux]

i have used 78 series front coils, custom coil hats and 5-link setup in the front. rear uses rangie rear coils with 3-link a frame, rangie ball joint for a frame, wide track hilux diffs with custom mounts.

[big bundy]

killalux, does it flex anygood with the 78 coils?

[slosh]

killalux I've thought a lot about your setup as I wouldn't mind doing 5 link front but how does it handle on the road compared to say stock hilux?

There is no reason why you can not use a 80 series front end.
Just a bit more fab work.
Only issue would be that a 80 series front diff is quite wide.
Chasis mounts will not line up with 4runner/lux chasis rails so fab work is
required same as coil hat locations.
Then you will have to increase the rear wheel track to match.

The bundera and 79 series assembly is very similar to the 80 except
it will suit the width for the lux chasis.Coil hats , diff width , chasis mounts etc.
They have the same front HP diff as the 80.
Benefit with the 80 would be larger brakes and stronger cv's , axles etc.
That's why the 79 series assembly is the go.
I wish I could of found a 79 series front end but had to settle on a Bundera.

flexes fine wthe the 78 coils, but i have a 7MGTE which is a bit heavier than standard 4 cyl.

as for handling, i have just recently changed front end setup from the 3-link that i had to a 5 link. the 3-link that i had was terible on road. the 5 link drives a lot better, but still has a lot of body roll, which will hopefully be sorted this weekend in the form of a pair of swaybars.

[mattlux]

thanks for info guys has anyone used 80 series arms and mounted them on top of the diff on the front, i am thinking of making coil hats but does anyone have any info on what springs fit in because there doesnt seem to be much room in front

Are those links back to front in the description?

I hope it's not that terrible

[chunderlicious]

i set mine up using everything off a GQ rolling chassis.... lines up pretty good straight under chassis rails like a ruf (2 inches forward) setup would up front. 8 inches wider than standard is the only problem.

it isnt easy and its a shit load of work doing it. setting up LINK suspension would be easier and work better as the angles of radius arms are sort of close to limit. but in queensland unless you use the jeep front end 3/5 link thing they use it isnt legal.

I'm looking into the bundera front ( which i have ) and my thoughts are that the IFS box wouldn't work because the pitman arm is facing backwards and would hit the panhard rod. How have you overcome this with your hilux? Pics would be great

Cheers Joel

With the 80 series pitman arm and rear swing ifs box it does clear the panard bracket and panard rod.
It just takes alot of mucking around to get angles correct to clear and get the drag link running parallel with the panard rod.

I had to rework the bundera panard bracket to achieve this.

nope, 80s box wont work...




At full lock to the passenger side there is about 5mm clearance to the panhard mount and pitman arm. If you move your diff forward a fair way (say 5 inches) i cant see how your going to use an ifs box without absolutely butchering the body.

The 80s front diff fits almost perfectly under a hilux, chassis width and coil placement is not an issue it all works without too much mucking around.

[Hales231271]

The steup using Hilux IFS box fitted with 80 series pitman.
The diff has been moved forward 50mm.
