But...it's 4.10 and down, so not sure how much use it would be for wheeling rigs....

No idea if this is a legit seller...not a fan of ebay, but the price is really good. I was looking for a Dana 80 rear ARB but need the 37 spline version as custom 40 spline shafts would eat up all the savings from buying this 40 spline. I don't need the strength of 40 spline as this is just going in my tow rig but for someone building an 80 for a rock bouncer (not sure what axle ratios they use since wheel speed is a thing for them)....maybe this will help them out.

Obviously, caveat emptor....since it is on ebay.

**EDIT**Oh and for those that don't know....apparently D80 ARBs have to be drilled/reamed out to 9/16" to accept the ring gear bolts.

EDIT2 4.56 thick gears are the lowest I found for the D80.....

40sp on a Dana80 makes no sense.
Get some 45/47sp shit if you're building that big of an axle.

Pretty clear from the title what's being discussed.... If one wanted 45/47 spline for a D80....they'd likely scroll right on past (or if they want an ARB, they'd have the side gears EDM'd...assuming there's enough meat...since ARB doesn't make anything bigger and at this price point, it would still be reasonable). Just sayin'. 😉
