There are no worries of misaligned tubes that could be welded with the wrong angles, and no broken welds to have to deal with.  Just think if you hit any thing with welded A-arms and bend them you now need to purchase new ones.

TCB RZR's Long travel suspension specs:

The length is extended 4" total 2"forward and 2" back for even a longer
wheel base that helps for a even a smoother ride on the ground and a more
level flight thru the air.
The width is 13" wider total 6.5" per side.
Ride height ground clearance varies from approx 13" up to 15" depending on
preload on shocks and tire size. Travel is every bit of the same.
Uses stock sway bar in the rear and front sway bar attachment can be
purchased for a extra charge.  For Dune riding, and Rock crawling we felt
the front sway bar was  found better left off of  the vehicle.
