FJ-80 top heavy

[pufft]

I was wondering what size tires you could get on an 80 if you trimmed the piss out of the fenders? I love my cruisers but from what I have read lifting them 6" is a bad idea due to the sheer waight of the body. I've heard Action Jacksons is very unstable and he goes through rear axle shafts like crazy with 40's. Well at least that's what they said. I know they say a lot but I am concerned about keeping the rubber side down. Any advise.?

So are you not lifted at all and not planning on lifting at all?

33's on stock w/ no trimming

35's on stock w/trimming and/or lowering bumpstops - wouldn't do it on a stock vehicle, you'll loose too much axle travel

35's w/ a 2.5" lift and lowering rear bumpstops

35+ = more lift and trimming and/or lowering bumpstops


For milder lifts theres no problem lifting an 80 and having it become unstable.

Offset wheels or wheel spacer/adapters can help to lower your center of gravity in relation to the width of your stance though you may have to do some trimming.

I see what you mean, I think, but offsetting the wheels isn't going to change your CoG (except for the weight of the spacers themselves - negligible )... It will however, increase the base area and make it less likely to roll over (everything else the same). Details, I know...

Mine has 9" of lift on 40s and is still pretty stable.

Yeah, if you've got a few buddies willing to ride on the high corner!

LOL, just kidding. I'm up 6", and have been off camber to 33 degrees several times. I won't say it felt good, but it hasn't rolled yet. I'm considering some spacers myself, especially as my rear tires just touch frame at full stuff.

I am trying to avoid 6" springs while getting to 37s so I will be going to OME Comp springs in order to stiffen up my body roll. I have a HEAVY truck and I sway like a reed in the wind with Js and spacers on 35s with sway bars in place.

I think the stiffer/heavier spring (OME Comp) will help me, just hope 37s stick under there okay...trimming may happen, will have to see!

I would like to stuff 37" MTR's with as little lift as possible. I have hummer wheels which I am going to recenter and make 6 lug of course so I can make up for specers that way. I've heard spacers put lots of pressure on the knuckles. I have a theory that I can get a 3" lift, trim, and bump stop to run 37". Anyone done this yet. Also probably will have to put a flat skid behind rear tires.

Edited. Thanks.

You can cut out your wheel wells and fit big tires, but I have no skills to do that

Are you using the heavy duty sway bars?

 

[GXO]

I think they are stock with extensions. Good point. Could beef those up when I move up and offset a lot of the lean.

Thanks.

 

[lt1fire]

are they really that top heavy??? i've not done any serious off camber stuff in mine but it's felt pretty stable with the 36's and the 6" lift.... anything you can do to off set this???

 

[GXO]

Well, I run more than 6000 lbs when I am loaded for trail, and I have a heavy rubber coating over the exterior of mine...probably not typical

Most of the off camber stuff I have run I have had no issues at all with. As I look toward 37s and a bit more lift I am merely trying to keep the body from leaning more...and I think the heavier sway bar approach is a valid one.

Here are some on sale: HD sway bars at Man-a-free.

A 4.5" lift with 37" tires is not going to be tippy in the relative sense compared to SWB rigs, and that is a reasonable lift target for 37's on the lower end since 80's are wide and have a long wheelbase. I'd go 6" in a heartbeat for 37's, because if you really want to run trails that require 37's you are going to need to lift to clear low hanging parts on such a long wheelbase. If you aren't going to run trails that truly require 37's, why go through all of that when 35's fit cleanly on a 3.5" lift?

To put it another way, if you really plan to take an ocean of sheetmetal and glass called an 80 onto trails that truly require 37's, excessively minimizing lift is not going to be to your advantage. ActionJackson has 3 linked the front among other things, so that is not a good comparison, third party information or not.

FJ-80s Are top heavy due to the Iron Head.......


Fzj-80s are not cuz we have an aluminum head


And to add some helpfulness here(maybe) My 80 FEELS less top heavy than my T100......

 

[GXO]

I tend to agree with the comments on lifts, etc.

I am currently floating toward the 6" approach to 37s, just need to afford the incremental parts to get there!

 

[alkaline747trio]

Dan, you could do what I'm gonna do for 37s, have the fenders rolled and run a 1-2" body lift with electric fans.

 

[GXO]

Since I have the other components to do it with lift I can get the height with only an investment of $400. The problem is the $2000 for the meats I want
