Whats amazing to me is this: such a HUGE difference in size to the 200 series. The 250 really comes in at a waaaaaay more trailworthy size- especially width and getting through narrow trails/ obstacles. I think for the bolt on roof...
Expect no less!
Tweaking, hills, wind all contribute to heat.
Your OEM temp gauge will barely/ if move at 97C.
Water boils at 100C, obviously you run coolant and have a proper functioning rad cap, which at 14psi will bring the boiling point over...
Do you have a transmission cooler? A442 generates a LOT of heat. Needs significant cooling. Can be a big factor in coolant temps as ATF is cooled in the bottom of the radiator.
Big cooler and a manual lock-up kit much cheaper than a manual...
I don’t understand 90% of what anyone is saying on here but if y’all do this mod and work out kinks and someone starts selling a kit I would 100000000% do this when my trans needs to be replaced some day.
Hazard, thanks for starting this thread and including "and more". I am in the process of swapping a ZF 8HP75 into my J80. I am using the TurboLamik TCU, which is the preferred TCU in the 8HP swap scene.

All the pieces required, not including nuts, bolts, gaskets etc.
1 torque converter to flex plate adapter.
1 engine to trans adapter
1 trans to transfer case adapter
1 transfer case input shaft made to fit 6R80 output
Good measurements good math😉
How does it handle with that much lift.
When I tried that much lift I thought it was sketchy.
I’m current now at 2 3/4” to 3” of lift with 39s and lot of cutting to make it work = a super stable ultra capable Rig.
Nice truck! As has been explained, the 4H button is not exactly the same as the CDL button on a full-time 4x4 80 - lock the hubs and then when you want 4x4, hit the button. In my experience, if you ease on the throttle and the hubs are locked, it...
Honestly, I have to wonder what people were thinking when doing stuff like that. It's about $30 in parts to do it correctly.
You need to return to a stock configuration. Please purchase a new set of fusible links (90982-08264), a new junction box...
I read this entire thread up to here and there has been zero reliable theories/info posted save post #10 which addresses the original question. I've broken random bits including rear nitro shafts but never an RCV and never hub studs, front...
what you describe is the typical rear pinion alignment after lift problem, but you don't usually see that until 4+" of lift. Did you measure your lift height or are you stating the label on the kit you bought? It's not uncommon to see a larger...
I was thinking maybe I would just grab a new 3rd member to setup new gears so I could do a quick swap, I noticed that Yukon has made a 8" RR High Pinion 3rd dropout housing. I see that it says:
"Yukon heavy duty dropouts feature upgraded...
