Outer Limits 4x4 Board

ok i can understand why people get 2" suspension and 2" body. cauz it keeps it legal (well in Qld) and it eliminates castor correction,extended lines, etc. but why do people get 3",4",5" suspension lifts and 2" body lifts? wouldnt the best option be to get the extra 2" in the springs (i.e 5",6",7" coils) you would get more travel too. so why do a body lift?

Body lift doesn't sag as easily, and shouldn't increase the 'top-heaviness' of the car as much as your only lifting body, instead of body and chassis.

Thats the 1st two things that pop into my head but I'm sure there's others

More room for bigger rubber, more room for bigger motor, more room to work on the POS, coupla quickies.

Cheaper, easy DIY


Or they have IFS... and can't lift the suspension anymore

Don't know what you used but the body lift I had didn't sag at all

by getting bigger suspension you are lifting the body away from the diffs making room for bigger tires.

I got no BL but it will still sag, only a few mm over years though

Negative.
Your bumpstops are still in the same spot so on full compression your tyres will rub.
Unless you limit your travel by fitting bumpstop extensions.

Yep exactly

DEPENDS - if your bumpstops are not attached to the body but the chassis then it is correct
But body lifts suck - learn to cut instead

I own my 4wd to go touring. I installed a body lift so I could squeeze in a larger long range tank - space under a shorty is at a premium.

The 33" tyres were just a bonus.

I have done that too
I have 0 susp lift and 40mm body lift and run 35s.
Some more +s for the body lift in my case is I have done a drivetrain lift as well with a custom transfer crossmember that tucks everything up higher and gives me better ramp over angle (a must with my huge wheelbase).
I have modified and lifted my long range tank about 4 inches for better clearance while still holding around 135 litres.
The sliders are a lot easier to fit with a BL as the chasi is a bit easier to get at.
And lastly. Have you seen how crap the IFS susp lifts are? They either reduce travel (to much torsion bar crank), stress the CVs (balljoint spacers) or add lots of flimsy parts @ big $$$ to lower the diff (essentialy just a BL anyway).

ok i must be a dumb sh** and missing something here... yes my bumpstops are connected to my chassis... so say i get a 6" suspension lift im lifting the bumpstop 6"s higher than where the bumpstop hits on the diff. by getting a body lift you wouldn't move the bump stop at all? i know it's probaly a stupid point to someone can correct me so i understand better please.

You have lifted your suspension 2 inches and can now fit 33" tyres under the guards at rest, awesome until you compress the suspension and realise that the 1.5" space you used to have between the tyre and the guard is now a negative half an inch. Easy fixed with a body lift.

Without the body lift you will not have any up travel on the suspension before you start hearing a god awful rubbing noise when your bigger tyres start to rub.

You have only lifted the bumpstop at rest, not at compression.

i would love to learn to cut, but i dont want to learn on somethin that i look at everyday, i.e. my truck

if someone wants to send an old bus my way ill happily practice on that first.









wouldnt a springover also give more room for flex b4 reaching the body?

There is only so much you can cut before you need to lift it if you plan on running big rubber.

Cheers Mick.

i reckon one of the big advantages is you improve approach and departure angles without altering the centre of gravity as much as you would by doing an extra 2 inches of spring height.

so is what your saying that if i had say 6" coils and lets say 33" tyres that on full compression it would still rub?

ROGQ wrote:so is what your saying that if i had say 6" coils and lets say 33" tyres that on full compression it would still rub?

will depend on how stiff the coils are, the offset of the rims, shock lengths etc. with a soft spring though it may rub, you can extend your bumpstops to prevent it, but that limits travel. body lifts are cheap and easy to do and have a few advantages. i reckon they are well worth while doing.

I think the point is 6" coils will be more likely to rub on the body than say with a 3" coil and 3" body lift. Due to the extra travel and bumpstop positions.

I say if you can get the extra suspension travel do it... if you can't do any more (or its gonna cost a crapload to do so), use a body lift.... Or you may just have IFS

thanks heaps for all your replies... sorta got me head round it now.. i know its not rocket science.
