lifting a 91 surf with 33x12.5x15 tyres

[dan-n]

hi all

i am wanting to give my 91 surf a lift kit to fit my 33x12.5x15 tyres that are on 15x10" rims. just wanting to know if i would get away with a 2" or if i would need to lift it 4"? if i lift it 4" will the cv's be on to much of an angle? what other bits and pieces would i need to mod to get it set up nicely

your thoughts?

should be sweet my ole girl was lifted via new back springs Raw nitro shocks and the torsion bars re indexed raised it just under 3 inches with 32's still heaps of room.

I wouldn't want to go more without things like a diff cradle drop in the front and rotating the rear upwards by way of eccentric top link/trailing arm bushes of more extreme cutting and rotating the diff head to take the acute angle away from the driveshaft yoke again.
I did break a front cv once but it was getting an absolute hammering at ashurst domain.

Hi there , the biggest lift you can get out of the ln130 without doing a front diff drop is 3" on the suspension and 2" on the body ,
We do 2 and 3 comprehensive lift kits for ln130 ,
Starting at a basic lift spring 2" for $250 inc and amada extreme shocks for $560 ,
Or we can also do ball joint spacers $250 inc ,
Adjustable tough dog panhard rods for $320 inc , We can also do 3" rear lift springs that will require running a extended rear brake hoses ,
Body lifts are $185 inc but require far more labour to fit ,
Cheers

Also if you are just lifitng the front via cranking the shit out of your tortions it will be worse offroad as you will have no downwards travel as it will sit on the top out stops hence the need for ball joint spacers on the ifs models if you are going for as much height as possible ,

91 surf

33x12.5x15 tyres that are on 15x10" rims.

what other bits and pieces would i need to mod to get it set up nicely ?

A solid front axle. Otherwise shares in a wheel bearing, steering linkage and diff factory.

my wagon got 2'' ball joint spacers 2'' diff drop removed sway bay and 26mm terrain tamer torsion bars. 65mm lifted cobra springs in rear. ome shocks up front and ranchos in rear. fits in 33''s sweet, no rub. want more flex now tho so it got the chop

[dan-n]

thanks for your help. i don't want to go really hi. the 33s dont give me much turning . i will keep those prices in mind, didnt realy want to wind the torsion bars up.

with a 2inch lift would i need to get longer brake lines?

if i got springs and shocks all round i would not need to change the position of the torsions?

thanks Dan

You dont have to "crank the shit" out of your torsion bars to get the desired lift. A combination of a small amount of lift ball joint flip and new good qaulity shocks will give you the clearance required with out limiting the travel significantly, and the bigger the tires the less compression you want in the suspension anyway other wise you will just rub on every articulation and corner.

the trick with IFS is to get the rear doing more work, find a smaller rated sway bar for the rear or remove it completely and get the LSD (if it has one) shimmed up nice and tight.

most sets of shocks you are looking at 200ish a corner let alone new springs and torsion bars and bushes etc, the surf has pretty decent voids in the gaurds anyway not like alot of 4x4's that require seam bashing and trimming.

sweet as thanks.

Sounds like a recipe for drive line vibration there !!!
Heres a quik pick of setting up diffs for higher drive shaft angles ,
getting the pinion angle to directly corespond the output flange is crutial unless you want ridiculously bad driveline issues , We use a magnetic Starret angleometer , For example if you do a 4" lift in a gq SWB the pinion on the diff sits at 9 degrees upward and the gearbox output at 3 degrees downward , Obviously you want the angles as low as possible but we space the gearbox down and extended the rear lower arms do get the angles matching at 5 up on the diff and 5 down on the gearbox ,
Sorry to get off topic i just couldnt understand how increasing the front diff pinion angle would help him ?

If it was me I'd ditch the 10" rims and go to 8". The 10s are heavy as hell, so wide they require massive flares and worst you can barely turn a corner before the tyres are chewing out the back of the guard. Also they will pop a tyre off the bead at low psi quicker than an 8". Upside of the 10s are they look tough, and that's about it.

That's my experience with 10 inch wide wheels on a Surf anyways

I think the suggestion around the front diff was actually to lower the entire thing. This keeps the CVS flat and allows for better travel.

+1 on the 10in rims. You will need to get a cert for them, not an issue if you get a body lift as you need a cert for that as well.

I recall seeing a post by UBZ, I think he said all he did to fit 33's was a 2" bodylift and a bit of trimming/hammering on rear of front guard. Would maintain factory driveline angles etc so c.v.'s would last longer.

Correct . Only a 2" body lift is required to fit 33x12.5x15 . -19 15x8 rims .
main advantages is it allows front A-arms to remain flat . giving equal up and down travel . considerably improving off-road performance compared to the torsions being cranked up 50mm

I just recently put 33's on my surf. Only a 2 inch body lift was needed but I had to pull off the factory fibre glass flares other wise it rubbed at about 1/4 lock. Problem now is I need to change ratio's in the diff as the 2.4 runs out of juice guickly with the bigger wheels to turn. Something to think about anyway.

4.8:1 diffs are ideal and worked well with 33s but I hear they are getting a bit rare nowadays

[Smurf]

I have access to front and rear 4.88 diffs for IFS Surf. from VZN130 Surf

[Jameshunt244]

How much? And can you get rear ones too?

[Jameshunt244]

Whoops didn't read properly, how much for both

[Smurf]

pm me dude.
