The back axle is NOT improved by the upgrade, even though they do replace the tires back there. The limiting factor on the REAR axle is the axle itself which is spec'ed at 17500.
A few of us are fairly certain that the RA will actually do 19500 ( it appears to be the EXACT same axle used on the 360 with a 19 lb or 19.5K lb limit) without a problem. FR purposely spec's it at 17500 to allow more toad weight (basically downgrading the axle below it's real capacity).
SO... if you go to 19500 on the RA, you will be cutting into your maximum toad weight.
If you have 19500 on the rear and 12000 on the front that's 31500. Subtract that from 33000 and you only have 1500 lbs for a toad. Smart car, maybe??
