I have no intentions of running a 10k high 9... I don't find it necessary... The 80 diff is adequate. I give Slee props for doing 2 of them but my goal again is to do it for less than 5k and done right.

Interesting comments and info in this thread. However going back to the OP's initial motivation I can assure you that doing it right and using an 80 diff is not the same. That diff is simply to small for that truck with the v8 and 37" tires. Doing all that work with a minitruck in there is not doing it right. You don't have to believe me but I think we have a little experience in pushing Toyota diffs as far as they could go with both Ben's old XRRA race truck and Joe's buggy as well as the Shortbus. Sooner than later you are going to grenade that diff, then there is no upgrade path.

And if you are not going to wheel that truck that hard, I would question the SAS requirement with 27" tires.

Now as to cost, we as a shop build the truck so they don't come back to us. We don't use used parts. We buy new. So once you add that up, the cost goes up dramatically. Price a new 80 series steering box and you will see. We have done the used part thing, and got bitten every single time. Now as a DIY guy, there are many way to save costs.

Also, one should not forget that you are also building the rear of the truck to match and that typically includes regear and also deal with the rear lift to match the front.

The truck that we finished now is not documented publicly until we get the owners permission, but I feel it is the best one we did to date. All Toyota parts, except for housing, True-Hi9 diff and ARB's. Also custom inner axle shafts.

I saw that truck in North Denver a few weeks ago.

Did you convert the front axle to 5 lug?
 
Christo - I think I can speak for most of us here - make us a damn SAS kit so we can slap on 37s and blow diffs every other trail run!!

112 inch wheelbase on 37s....hella fun i bet.

:grinpimp:

so would you say that the 80 series diff is almost inadequate in strength for the 80 itself? The 100 series curb weight is roughly 500lbs more than the 80. I agree though if your going to spend the time and $ it is better to build a more solid stronger front diff.

If you leave an 80 stock with tires it was designed for then it is ok, or even up to 33's. Once you start pushing 35's and larger then yes, I think it is too small. It is very vulnerable in reverse. 100's break that same gear set in the IFS applications left right and center. Different issues that lead to that.

80 Front ring and pinion breaks are not an epidemic but they are not uncommon either.

As for the guys wanting a kit, sorry, not going to happen from us.

Add me to the list...please :D
 
Maybe we should do a group buy for about 50 people :)

Rumor is it can be done for ~$5000 at that price Im a possible maybe depend on when this will happen and pending the final cost shipped.

If you do most of the labor yourself and collect all the SAS parts you think you need I still believe you are coming in closer to $10,000... Think about the cost of a custom properly built front axle alone - start with your housing of choice (several already suggested Currie, RuffStuff, etc) and once stuffed with locker, custom axles, new gears to match front and rear you've already spent $4-5K...

I have plenty of friends that have axle swapped various Jeeps, XJ's, CJ's, TJ's, etc. (and some Yotas too) - some done better than others but most are not up to "landcruiser" standards that I would run under my 100 series... Most of the Jeeps and older Toyotas I've seen axle swapped are beater dedicated wheelers... The Jeeps are cheap and alot easier to swap but things always seem to break on them too... I have a fully built Toyota 8" mini truck front axle with longfield axles, hi steer, disc brakes, caliper upgrades, etc under my FJ40 but it weighs half what my 100 series does... Most people that trail ride their 100's have them loaded full of gear and people so I wouldn't trust the smaller front diff either - I've only made my 100 heavier since I started upgrading everything. I also see alot of value in keeping it as much Toyota as possible...

That said if you guys figure out a more affordable way to do this I'm all in... You will easily spend several thousand on a properly upgraded IFS front end too... For someone that hasn't started a build yet that money could go towards a SAS or you could re-coupe quite a bit of money if you are already running a fully built IFS 100 by selling some of your goodies...

Maybe we should start building a "essential 100 Series SAS parts list" - a group can usually help with resources that drive cost down. I've wanted to do this for years so I'm really very interested...

Or... How about a "SAS in the Hills" - we just need a group together and assembly line a whole batch of 100's at once... Who's got the biggest shop? :hillbilly:

Lol. Poor Christo... He explicitly states they aren't ever providing a kit for this...haha. What power do the masses have if they should demand such a kit? :)

You guys should reach out to 4Wheel Underground. He's working on a 3 link kit for the 80, maybe with enough interest and a donor truck/parts, he could fab up the links and brackets to make this work. They're out of Socal.

Much better to control the outcome by only offering to do such an install himself. For the guys out there like RockJock that have the tools and ability, they dont need a kit anyway.

just my .02

Agree. It seems like folks think there could be a bolt on SAS "kit".

No such thing. Even if you have all the parts, you still need to cut, weld, grind, measure, cut again and weld some more. Finding the parts you need is the easy half.....
