37s on a disco is it next big thing to have

[mentalmoshio sophs V8i]

seen these massive tyres and at 125 quid a piece im sure thinkin about it but i going to need

a other 4 inches of lift at least

brake pipes

relocated shocks to stop belly out on archs

rear exhuast system in the way of wheel movement.

wheel arch flares

axle ratio

steering problems

any body done this before.............

like to know any other problem areas

[clbarclay]

I suspect those tyres are they are Super Swamper Boggers made by Interco, which is what the anacondas were based on. I have their 34" LTBs waiting for substantial outer wheel arch mods to a RRC which is already suspension and body lifted a good 3"


Kiss good by to your half shafts.

Personally I would start a fresh for a set of 38" tyres, using something like Toyota axles and you might as well make the front end 1 or 3 or 4 link whilst your at it 8) Build it all with a lot of lift and reroute the brake lines along suspension links so you don't risk stretching and provides a degree of protection.
Hay, whilst your at it pickup/tray back it and have exhaust stakes behind the cab so clearance round the axle/tyres is not an issue.

Go one you know you want to :(shades):

[mentalmoshio sophs V8i]

check the american landie on 38 in the extreme one gallery. its that type im thinkin of. besides  i use it every day so on road handlin will have to me a main issue to.saw a range rover on 33 for road with a 10 lift and 40 inch mud tyres.

THE TYREs ARE NEW FROM SILVERLINE 4X4 AND NOT AMERICAN ONES BUT THEY DO LOOK GOOD BUT WAY TO WIDE PAST 12.5 WIDE

that is going to hurt your pocket a lot......you will have some serious issues to contend with offroad.and onroad i doubt you will ever be able to have a comfortable ride let alone a safe ride.....i ran a six inch lift on the rear with 36s and the car stood over 7 foot  high...you will have to sort out driveline angles for props ect as there is nothing you can buy off the shelf for that.also your transmission,half shafts,diffs,axle mounting points will all need to be changed and seriously strengthened!!!!

going above 35 inch tyres i believe the car becomes a buggy (in american terms) and not a car.

plan for the road is to

lower the anti roll bars by 6inches with a customade drop kit. never took them off it gives a form of hydric control without the ace system on later models

extended bumpstop with lower mount custom made

30 degree propshafts 300 quid

cranked rear trailing arm 150 quid

6 degree qt radius arm with castor corrected bushes 300 quid

4;7 diff a local guy does them for 35 quid

24 spline half shalfs.  50 quid each

so it should ratain normal road holding except for the increase in the centre of gravity

or might cut spring hangers of and lower them by 2 inches and reweld them also drop the shock mounts by 4 inches

[chuggaman]

not trying to p...on your chips but i see a few problems or issues.the stuf you are looking to buy ie

extended bumpstop with lower mount custom made

30 degree propshafts 300 quid

cranked rear trailing arm 150 quid

6 degree qt radius arm with castor corrected bushes 300 quid

are not going to sort out those problems.....

4.7 is not going to correct the gearing to normal and an increase in lift is going to affect  cog whatever you do....which will in turn affect road manners and seriously affect offroad fun....

standard 24 spline half shafts will break with the torque of your engine...

if you are seriously planning that size of tyre then expext to increase your credit card limit and make sure you can weld.........

like i said it is just some friendly advise and not a dig at you but this will cost a fortune and i repeat there is nothing you can buy off the shelf that will accomodate your needs....you are in hybrid builders territory and not a lot of people will give their answers freely...

if u go to rds-eng.co.uk that guy gives all the problems and solves them or try discoweb.net for 38 craze landie

or try discoweb.net for 38 craze landie

Their are some nice landys on that site, come to think of it its a good job I'm single as I dread to think what a miss's would say if caught looking at a site like that.

Ohh  =P~

[Richie_EB4]

Agree...........looks cool but dont think you wouldget much articulation off road.

[beatmasterdave]

wow! well, im after a lift and fat ol' tyres. are you sure about 38s?
ive been in dream land too and looking at 33's, check my thread out
http://forums.mud-club.com/viewtopic.php?t=40339
even thats a lot of work. ok, i'd love it to be kinda good offroad, but it would look awsome! 38's are nuts. try http://www.rdseng.co.uk/Products1.htm see what they say, as they do it day in day out. goodluck, and if you go for it, chuck your pics up on here!!! :D  :D  :D

[Disco-Ron]

Dave, even 33's can be a pain... i recently put 285 75's on mine, and broke two diffs within a month, i now swap over to my old wheels with 235 85's for off roading, and only put the big ones on for road use, it's a right flippin pain....!!

Steve,

As Chugga says, "not trying to p*** on your chips" but just pointing out some areas that may need a little more thought as we don't want you wasting your money on something that's not going to work.  

What are the 4.7 diffs from? If they're Series diffs then they won't take the loading. They will need to be alot stronger than standard, maybe a 4 pin that's been pegged and £35 for a diff says they're used Series, 10 spline diffs.  

The 30 degree propshafts may also cause you problems as, although they go to 30 degrees, they will vibrate like hell on the road if you ask them to opperate at that angle all the time. You should be looking at the likes of a double cardon jointed propshaft if you want any sort of reliability from the U/Js and a lack of vibrations.

I may have read this wrong but, why do you need 6 degree caster corrected radus arms with caster corrected bushes fitted? What height of suspension lift are you putting on? I see you have a +2" on there now and I've also seen your thread about a 3" body lift but the 6 degree corrected radius arms with normal bushes should do upto a +4" lift.

To keep the ARB's at the right level then you only have to drop the chassis mounts by the same amount as you've raised the suspension, although you may find that this will reduce the departure angle at the rear. I removed mine and got springs rated so that ARBs weren't required.

Something else to think about is what your insurance will have to say!!
You must inform your insurance company about every modification to the vehicle because they could well turn round and refuse a claim leaving you liable for everything and open to a charge of driving without insurance!
 
At the very least they may want you to get an engineers report on the modifications before they will insure you, at worst they won't insure you. Some refuse to insure modified vehicles completely.   :roll:

Unfortuately there's not a cheap way to do what you're looking at. Some of the engineering will require some thought to get it work as it has to be strong & safe enough to put on the road.
My best advice is to have the idea of where you want to be with the vehicle and then do it bit-by-bit until you get there.

4;11 diffs was the other one or portal axle to raise the diff out the way by 5 inchs than normal

[mentalmoshio sophs V8i]

THIS ONE HAS A 3 INCH BODY LIFT

5 INCH LIFT SPRINGS

2 AXLE SPACER

HENCE U NEED 9 DEGS OF CASTOR CORRECTION FOR 6 INCHES OF LIFT ON THE SPRINGS

HE RUNS ON 38/14.5/16

ENGINE IS 5L V8 TUNED RUNNING ON A 4.6L AIR SYSTEM

[mentalmoshio sophs V8i]

HE WE GO

[clbarclay]

Rather than get carried away lifting the suspension until it stops catching, take a grinder and welder to the wheel archs inside and out. You will probably lose the rear doors on a 4dr but 38" tyres arn't exactly practical either.


Lifting the suspension that much puts a excess strain on other suspension components. For instance the rear trailing rams which when run at such a steep angle will try and turn under the car if driven forwards into an obsticle or the there tyres revers into an obstickle. It won't matter whether they are cranked or not as the pivots will still be in the same place.

The same goes for the front radius arm, panhard rod, A frame etc. as well as parts of the chassis like the anti rollbar mounts.

[mentalmoshio sophs V8i]

cant stand discos what have been chopped all over the place just to make wheel fit beside gives room for bigger ones. saw many discos on a 6 inch lift running on 35/12.5/16  the 3 inch body lift  will make 38 look a mini monster truck. as for axle movement bits u can grind the rear trailer mount to gain more poivet and control it with a check stape and bumpstop hight . its ground clearence im after the lpg tank sit 3 inchs below cills which effects ramp break over angel with the added increase of apporch and departure angle

[Budgie]

Another thing to think about is that as you go up in suspension height then, unless you lengthen the radus & trailing arms, then you'll reduce the wheelbase as the axles rotate around the fixing points for the arms. This also has the effect of leaving the nose of the diff up in the air and the speing seats on the axles will be out of position.
Putting caster corrected bushes on a 6" lift will mean changing bushes quite often because of their construction. They're walls are thinner on one side and the strain they will be under will cause frequent failure. Correctly made radius arms may do the trick but you'll be better off with either custom made swivel housings and lenghtened radius arms or cutting all the mountings off the axle, rotating the axle to the correct position and welding the mountings back on again.
 
You'll also have to do something to lower & lengthen the rear A frame balljoint so that the top of the rear axle is in the correct position.

To be honest, if you want extra ground clearance then get shot of the LPG tanks and put one in side. It'll be far cheaper, and a lot less work, than all the engineering you're looking at to make the suspension fit around the problem caused by the tanks.  

Oh, and here's mine on a +3" lift, cut arches and 33x12.5x15's.





Sometimes extra height can be a disadvantage like for getting under overhanging tree trunks:

[mentalmoshio sophs V8i]

nice but you have 16 inchs of clearence fom the ground to tree slider if i had the same wheels and lift as you i would have 13.5 inches clearence. the lpg tank are not moving there is nowhere else believe me

[extreme90]

why do you want 38 inch tyres  :roll:  :roll:

[redhand]

nice but you have 16 inchs of clearence fom the ground to tree slider if i had the same wheels and lift as you i would have 13.5 inches clearence. the lpg tank are not moving there is nowhere else believe me

Surely the 1st thing thats gonna ground is the diffs and all the bodylift in the world won't change that. Unless your planning some extreme pay and play driving Your not gonna find anything on a greenlane that'll need 38" wheels.

exactly  :roll:
i just think its pointless unless your planning on going ladoga next year  :roll:

[mentalmoshio sophs V8i]

never intend on going greenlane its got no appeal. got a motto i  do intend take my truck home in one piece hence the extreme stuff is out  for people how have not worries what will happen to it.

the best offroad fun is rtv or a fun day believe me its, like what motocross biker would use

diffs can belly out but never had that problem just fit diff gaurds and knobby tyres . its my ramp breakover angle which is my discos downside

most of would agree a disco on 35inch simex is a best yes . well 38inch will correct my ground clearence by 1 and a half and the lift does the rest to be the same as one on 35s

here a question. a mate rekon a standard disco is better offroad than one on 38inch or 750r16 . he does have one buy the way

[mentalmoshio sophs V8i]

can anybody who has a disco or range rover with 35s or bigger on plz leave me everything u had to do to it that way i will know for sure what really involed thank you

[suggs]

who sells tyres that size for that price??

[extreme90]

a fellow challenge friend of mine runs his disco on 35" simex, not bobbed or nothing, and his will go anywhere my 90 does

you simply dont need massive tyres

[mentalmoshio sophs V8i]

they will be available from silverline 4x4 there not online yet but they are in lroi this month its in the middle pages

[chuggaman]

here is a shot of 36x12.5 for perspective.its next to my washing machine.
