Are 172 and 182 cup rear axles the same?

[Cunney]

Would appreciate some quick advice on this from somebody who is 100%

Cheers lads

i believe the main rear beam is the same, but the stubs are different (don't forget the offset difference is there for a reason, ie 182 rear axle being wider)

182 axles are also stronger, if you compare them side to side they have extra strengthening around the shocks and springs. The also have a thicker 24mm roll bar..
