With my driving style, the auto, relatively light weight, I think they would FOR ME...though I have no experience with the new rear axle shafts, I'm sure they are good..

How do you drive, stick or auto, what does it weight, and what kind of 40's? Red label Krawlers would put alot more stress than MTR's one would think.

i like the GO pedal, but i still drive conservatively. it has the stock 4spd. don't know how much it weighs, relatively light considering there's no engine :rofl: i was thinking of iroks, oh wait.......they're 39.5" :rolleyes:

i'm just trying to get a plan going, you know. :D

30-spline longs in front, inners and birfs

poly chromos in the rear (tho I never broke a stocker...likely cause other crap busted first)

fine spline pinions are a must

mini lockouts in front, mini knuckles or BETTER the new Marlin 6-stud knuckles (if they ever friggin come out)

ARP studs for the histeer and the lockouts

40's are pushin a Cruiser axle pretty damn hard, I don't care what you build it with. I do have the distinction of bustin a Gen2 Poly Perf 4340 inner, first one evah.....and that was on 37's. Hell, even the coarse spline front pinion held (surprise)

next issue is air time, if you leave the ground at all, it's worth it to top-truss the front and rear housings...

What motor?

I bust shafts with 36" tires in my 40 with a 350. I don't have the fancy shafts though ;)
