FZJ 80 Axle Swap into 98 100 series

[Nicholas Hanke]

I have been building my hundred for 2 years now and have finally decided to do the SAS. I am using a 93 FZJ 80 axle for the front and keeping the stock 100 axle in rear. I will be converting the axle shafts to 6x139.7. I am putting in 5 inch 80 series springs in the rear with the 5 inch OME shocks for the rear. The front will have a 93 FZJ axle with 12 inch travel coilover. With a Robinson adjustable Panhard bar and upgraded drag link and tie rod ends. I just got the vehicle back from getting vinyl wrapped today and dropped off the tires and rims to get mounted and balanced. My goal is to have this SAS and rear lug nut conversion done by Christmas. I am going to try and do daily updates until it is finished. Tomorrow I was planning on finishing the rear, but rotors won't be here until Friday. I will go ahead and install shocks and springs and figure out how long I need to make my brake line extensions, bump stop drops, and I am going to midday the rear sway bar to work as well. Once I am finished with that, I will start chopping out the old IFS. I was already geared at 4.88s and locked front and rear. So the 3rd is currently getting geared and locked and once I get that back ill finish the knuckle job and get the Axle ready for install.

Very interested in this thread! I haven’t ever really “needed” a solid front axle on my 100 series, but I sure would like to do it so it would be virtually unlimited with the advantages of the 100 series (V8, wonderful luxury) and the advantage of the solid axle front end.

My 100 series just rolled 200,000 miles, and I can’t ever imagine selling it or not driving it. I see new trucks roll by, and just think about how my ‘hundy has never let me down, how good it works and looks, and I can’t think of having a car payment ever again for my daily.

Sub'd as well! I look forward to seeing more!

Cool, good to see much effort going into a 100! People talk about it here in aus occasionally but we’d never be able to get one registered due to our strict mod laws. Should end up with a massive lift in the front due to the lack of chassis arch over the axle?

So are you going to run two different wheel offsets? And convert the hubs To 5 wheel studs with M10 axle studs? What about steering - swapping the 80 box in too I guess?

If you want any pics of how a 105 is set up let me know.

Sweet wrap job. Which vinyl is that?

Rear axle is much wider than the front axle off the 80 due to very different wheel offsets. And typically you want a wider track in the front, not vice versa.

Are you going to run 80 series radius arms? Steering box? Doubt you will be done by christmas but best of luck

It doesn't have to have a ton of lift, and the frame shape is (surprisingly) not as limiting as I first thought it would be. The oil pan is more in the way than the frame. The width of the frame is more of a problem than the arch.

He mentioned converting the rear axle to 6 lug, rather than the front to 5.

Here's a pic of mine showing the mall-ready ride height.

Yet you still havent done any real wheeling?

 

[allan man]

Subd. Thanks for sharing.

 

[Eicca]

I admire anyone that has the balls to pull that off.

That said, I’d personally rather replace the ball joints ten times before attempting a Birfield.

Following. I really enjoyed @I Lean SAS.

Theyre not that bad

Yeah, I just managed to flowed thru 3-4 feet of snow going 75 mph on Highway 395 near Mammoth Lakes CA 2 years ago. Road hasn't gotten cleaned up and everybody was going 25Mph until I showed up. Everybody started following the beast thereafter. Some other trip were mainly fire roads in San Diego are but managed to launch the truck off 4 wheels. check out #extremelandcruiser Instagram.
