Outer Limits 4x4 Board

im lookin at putin 35s on my 80 series cruiser and just bout everyone has said that it has to hive a body lift or a bigger suspention lift in it!!! so what is better to go 4 inch suspention lift or 2 inch suspention and 2 inch body lift? cheers anthony

4 INCH suspension for sure. easier to do , more flex offroad, the body is bad for cracking around the bodymounts now so why add to it , don`t have to then raise all your barwork to suit , the list goes on .

x2

what bout center of gravaty dose that play a big part of it? or isnt it to bad? cheers anthony

suspension lift alone won't help you clear bigger tires. it's the distance between the hub and the guard WHEN THE AXLE HOUSING IS ON THE BUMP STOP that dictates what tire size you can run. a suspension lift doesn't affect this distance.

So do your 4 inch and extend your bumpstops.

or cut the guards and then its more legal...

4" suspension lift is plenty to clear 35"s on an 80. and it will get you plenty of places that will leave you with brown undies before the centre of gravity is a problem.

if you are worried about COG go for a 3" lift,and incease the length of your bumpstops to suit

3" lift will have less complications with handling and driveline etc, 4" lift is enought to create quite a few problems with handling, brake lines, driveline vibrations, extra components required.

I have 4" lift in my 80 and am seriously thinking that if I lift my new 105series, I will only go 3" lift

Hey Arron, cutting the gaurds aint gonna help clearance to the inner arch's

It's either a bodylift or bumpstop extension.

A 2" body lift and a 2" suspension lift will keep you legal in most states.

limiting your travel and putting your COG higher for no particular reason.

bodylift or guard trim...

you limit the up travel by 30-40mm at the most, down travel is not reduced.

if you want to see a good example of what can be done to run large tyres without huge lift sign up and have a read here

suspension travel seems to be a non issue here^^

so why not limit up travel 30mm on standard suspension and not raise the COG?

Because the wheels wont fit??????

If the wheel and tyre combo won't fit like this, it won't fit with just a spring lift anyway.

so 33's don't fit on a standard 80 then? (33's at full stuff = 35's with 25mm extended bumpstops at full stuff)

to all those that say your "not limiting down travel tho with extended bumpstops"... you are in effect, because a 4 inch lift is already using up 4 inches of down travel (compared to standard setup) at ride height. your suspension arms etc only have so much range of motion they can go through. with a body lift you don't lose the 30-50mm travel by spacing the bumpstops, and still can reach the same hub - chassis amount of down travel at full droop as a spring lift (assuming all suspension links stay the same, if not, we're not talking a simple lift anyway)

who are you and how do you know my name?!? =)

Guard chop to me means moving the inner guards as well... not just trimming the outside to make it look pretty (or ugly).

How much travel do you want with 35's?

2 inch sus and 2 inch body.

By doing a 4 inch suspension lift you will never get your ride and handling close to what you can with a 2 inch.
Keeping your roll centre and COG low has major benefits. A 2 inch sus 2 inch body lifted vehicle will out perform a 4 inch lift.
It's worth the extra time money and effort to do it right and achieve better results.

33's on a stock height 80 would probably rub on the guards when tunring.
35's on a stock height 80 would definatly rub on the guards when tunring.

from my link above. Very well set up by a very knowledgeable bloke



this thing is running 37"s with a 3" lift and bumpstops and longer shocks to suit.

travel will be limited by coils and shocks before it is limited by the range of movement in the suspension arms unless you are driving Tuff Truck

Halleluja,, i've tried to make this point a few times on Outers.

On a truck with standard suspension mounting points, i'd do a bodylift over a bumpstop extension everytime, because the standard suspension geometry is so positive in the full compression range, that it's such a shame to lose it by limiting compression travel.

How much travel do you want with 35's?

as much as you can get without becoming too soft and unstable?

so 35's would rub under compression then?

q78's work on an 80 series with just a 2 inch bodylift. why do the springs?

yeah, problem is everyone gets their nose out of joint because they realised they spent a couple of grand on something that's only useful as a penis extension.

not exactly a simple lift. custom suspension geometry. start mucking about with aftermarket suspension arms etc, and all bets are off... there are many ways to get good results then, but outside the scope of "spring lift or body lift".

Funny you mention that, because the topic is 'Suspention vs body lift', Not 'Spring vs body lift'.

The last time I checked the 'suspension arms etc' were part of the 'Suspention'

You think people would know how to spell 'suspension', It comes up alot in 4wd talk.

BUT If running say 2" bumpstops, with 3" lifted coils, you could run 5" shocks. So downtravel is not lost.

When running 4+" shocks you need bump extensions anyway to stop the shock bottoming out.

By the way, on my 105 i ran 35's with only 2" coils. Had 2" bump extensions in the rear, and none in the front. It didnt rub anywhere like this. Also, from what ive read, 80's can fit bigger tyres more easily than 105's.

and if the original poster doesn't know enough to choose between a spring lift or a body lift, you really think they'll know enough to get the most out of their suspension arms, to suit the taller coils?
