Default 2618: Researching Upgrade from 3500 to 5000 lb Axle

Hi all - I have been searching for any information on upgrading the axle/wheels of my 2618 (just purchased) to increase the GAWR and tire loading capacity up more toward the listed GVWR on my rig.

Current Limits:
GVWR = 4190
GAWR = 3640
14" tire max load is 3740 (1870 each side)

Future:
GVWR = 4190
GAWR = 5200'ish
15" tire max load is 5660'ish (2830 each side)

All numbers above in lbs.

Has anyone done this upgrade to their rig that could point me in the right direction on considerations, costs, etc?

My only thoughts - not particularly useful maybe -

1. It is critically important that the new axle be installed at exactly a 90-degree angle to the frame. This isn't hard to do, and a pro will take care of it without thought. If you have a shade-tree installer, be sure it happens.

2. If you have a lift kit, you can get rid of it, and buy an axle with a larger "starting angle".
