I had no idea that you had all of that underneath your 80. I need to take a closer look for the next time that I see you.
It’s a sleeper 😁
 
I'm running the stock set up with the steering behind the axle. I really like this setup as it protects the tie rod and hydro ram.
As far as mods 5-29s with OEM E-locker, full Truss from spring perch to spring perch, knuckle gussets top & bottom, bash plate front & bottom, All ARP hardware and RCV Ultimate axles.

If I were to go high steer I would use the Front Range High steer Knuckle kit with there keyed steering arms. Steering arms are keyed to the knuckle. SWEET

Only problem with front range is the reliablity of getting parts shipped unfortunately
 
Glad I found this thread, great info here!

I'm planning on SAS swapping my 3rd gen and I'm on the hunt for a driver drop axl, to keep my Eco crawler duals.
Im not interested in tons, I'm considering a Waggy 44 or flipping an 80 series front and sticking with 35s or maybe going 37 max. I mostly crawl but need highway road manners.

Not looking to hijack, just saying hi and why I'm here; my other rig is an 80.
Feel free to derail. This is exactly why I stated this thread. I’m not positive on flipping the 80 front axle. But I know I e read a bit of people doing it.

IMO the ideal scenario would be a set of axles from an early 80 series with a semi float rear and build a 9.5/80 hybrid axle. That would give you a driver drop. If you link it you can run a RHD steering arm and y-link steering.

There not as bad at getting the the knuckles out 🤷‍♂️ if there in stock.

I have a set of axles off my 94 with open diffs but I was thinking about keeping my 3rd gen e-locker rear in place (for now) with factory rear arms.

If I flip the 80 front I would go with hellfire high steer vs Y-link (like a D44 uses) and make more room for 3-link out back with a relocated panhard. Probably make my own axle tubes and swap/clock the 80 knuckle balls.
To throw another thing in the mix, Trail Gear just started offering 80 knuckle balls
Diamond only offers 40/60 series KBs, is that accurate? I hate TG lol

No they offer a 80 series as well
 
I never understood the 30 spline upgrade, the bell's break on the birfs, not the shafts. The upgraded bell is what your after, RCV.
Brakes are easy to put together, if you are keeping the toyota knuckles the 6 shooter are good. If its an 80 axle the Hellfire stuff is nice.
 
I will, great idea!

Looking at an '83 front for a flip. Seems easier to convert to high steer and a similar upgrade to 30 spline. Any downside to going this route? Brakes?
Width, a mini truck front axle is only 55.5” wms. Your rear is 60”.

You can do the IFS hubs and FROR big brake kit and run up to 5th gen brakes and gain about 3” of width but the front will still be narrower. The more width you gain past the knuckle means more leverage on the knuckles and trunnion bearings compounding the strength issues. Plus they steer like s***.

Yep, If you want to keep it all in the family 80 series stuff is the way to go 😁

80 series axle flip here:

That's a great idea, flipping the axle horizontally, especially if I'm gonna link it!
The thought of removing the mounting flange tho...
