The axle shafts neck down a lot if I remember just b4 the carrier bearing. Make sure u check that out b4 u go to far into the project.

I can't remember the poster but there is a thread on here all about that diff and its upgrades etc. IIRC the shafts weren't bad size wise. custom shafts may be cheaper if you go with a 35 spline carrier/locker. IIRC the stockers are 32 spln?
Search justdifferentials, it may have been one of his threads.

Redrill them sounds crazy but I did back in 86 and flogged it for 175K without any issue.
Yeah, I didn’t think of that but wouldn’t be afraid to. As long as the Tundra flange can support 6-lug.

But if @bugsnbikes was wanting to narrow a housing he’d be getting custom shafts anyways so I guess it’s kinda a moot point.

The infamous Raisin runs the Tundra diffs , since way back when, and it's pretty sick with the Toyota V8, so unless you run it under a pig everything should hold up really well....

Maybe Cruisermatt can post a pic - Cliff is the current owner and he's not on here much.

I'd run the stock width with deeper offset wheels.

Actually the Raisin has load-bolted 9.5" front and rear. I was crawling around it extensively at Trukey trot.

You could look into a 100 or 200 series 9.5" rear axle. I think the ring gear is thicker and the pinion is beefier from what I remember. Also the axle shafts are 32 spline vs 30 spline which gives an increase in shaft strength of about 25%. However I have never inspected the 32 spline shafts to see if they neck down much.

Is the 200 9.5" the same as the 100 9.5? Or both 32spline pinion
I believe that the 100 and 200 differentials are the same with the beefier pinion. AFAIK both also have 32 spline axle shafts. The 100 series rear axle has a slightly offset rear differential and the 200 has a centered rear differential.
