SAS on a 100

[Micah]

Me and my brother both drive a cruiser and we are trying to get our dad to get a 100 series so that the family will have a 60, 80, and 100 series. We were wondering if anyone one has ever done a solid axle swap on one. Any pics would be really nice. thanks in advance

No one yet. I am working on Christo to do one soon. I think he is getting warm to the subject

Would it be possible or cost prohibitive to get 105 parts for the swap?

i am doing research on a simular issue.

i am doing research on a simular issue. i am thinking of doing a sas on a 02 tundra. i have not found any one that has done it yet. its my dd so i want it to be perfect. it will be sweet if sucessful.

105 parts are the same as 80 parts, not reason to outsource the same thing.

Joe Jovonovich has a solid axle Tundra. It is bad to the bone and for sale too.

Been done. These SAS's use a FZJ78 front axle. The LC105/80 front might be too narrow.

Joe's Tundra uses leaf springs up front, like you are saying Hoser. It works well and they are easy to set up, but it isn't very elegant and probably not what a 100 series owner is after. I would think that radius arms would be the easiest way to add coils to the front.

One problem I see with the 80 front axle is the bolt pattern, you would either need to change the pattern in the rear to six lug or those 3" spacers could act as adapters to five lug in addition to adding width.

What about the steering?

R&P or RB?

Are those pics of the SAS`d 100 you posted available online full-size ? I would like to see them bigger

I've seen several SAS Tundras. Here's another one. But all the ones I've seen use leaf springs rather than coils.

I have one! I own what I think is the only coil-over SAS tundra in existence. I think I was the sixth guy to build one, but mine differed in that I didn't want the limiting leaf springs. Mine has 12" King 2.5" coil-overs up front and 14" travel Bilstiens out back. It is supercharged locked front and rear with 4.88's and 37" X-Terrains. It uses a HPD44 from a 1978 F250 and has a bunch of custom features. Took almost a year to do in my garage, but it's right and very capable
I have pics of it posted over at Tundrasolutions. Go to the photo gallery and look for my gallery, flyin6.

105 parts are the same as 80 parts, not reason to outsource the same thing.

80 has one extra part on the hub, and 5 others with different part no's, which would need atttention, as they arent "all" the same.

105 is an 80 chassised body looking like a 100, but alot of the panels are different, and they run the wider offset wheels than the 100 ifs.

80 parts with 105 series hubs would be the way to do the conversion, but I would be looking at just doing a better A arm system instead, if it were me, than go backward in technology.

Get your act together Darren and hurry up and make a kit to do this, there are lots waiting for it I'm sure!

I scanned them out of LC mag, so just the tiff.

The 78 axle is supposedly as wide as the 105.

Leaf springs on a 100 is

 

[hoser]

Here are the front track widths (not axle width). The track width is measured from the centerline of the L rim to the centerline of the R rim. So the offset of the stock wheel also contributes to the track width.

100 series IFS
1620mm (63.8") +60mm offset wheel

105 series
1605mm (63.18") 0 offset?

80 series
1595mm (62.8") 0 offset

78 series
1690mm (66.54") offset??

I'm glad this thread is linked to the TundraSolutions site, or I would not have found it.
My next project is probably going to be a straight axle 100 series LC. I love Land Cruisers, started my wheeling a century ago in a 40 series.
Anyway, I'd like to essentially do the same thing I have done on the Tundy with a newer LC and be able to run 35" tires with that nice V8 power and all the nice ammenties Toyota builds into the LC. So, I'll following this thread and others who discuss the SAS option.
It isn't impossible, but it is a bunch of ciphering and plain hard work. But what you end up with is a different much, much, more capable vehicle.
