no. the tranny maybe be a concern over time with abuse but axles will be fine.

Stock 4L60E is garbage , Ive been through 3 of them , IMHO. As for the Axles Im not a Huge fan of the 10 bolts in these things for a number of reasons One mainly being the G80
To be honest On a stock engine most of these parts are do able but your horsepower numbers will shorten their life greatly. I would go to a 14 bolt 6 lug to be safe

4l60e is not garbage. That got drag cars putting out 1000 HP using 4l60e's. Just need to rebuild it to handle the new HP like any other transmission's.

sounds like a personal issue. Maybe you should see someone about that.

He said stock. Stock they have issues, rebuilts can handle some power.

rebuilds that dont have upgraded or improved parts can be stock too. besides no idea why don would continue to use stock tranny with no upgrades considering the tire and wheel setup he has tho no info on his gear ratio either which will effect things as well.

Well Even with stock tires and a Rebuilt, "updated unit" I didn't have any luck with them. when this one decides to crap out I will be buying a 4L80E
Its has stock axles on it right now its got 285x75x16 1 size up from stock. Will have 35x12.5 tires hopefully by summer after i install 6' suspension lift. tranny has been rebuilt twice sicne i owned it in the last 7 years
