Hey codie,... welcome to the board.
There are several manufacturers of tubular a-arms.
I would suspect they are just as strong,
if not stronger than the stock, stamped steel version.
Like XXL said,... they have been discussed here at great length.
I own a set of AirRide Technologies StrongArms a-arms (for my '86 project truck), and just put a set of Thorbecke Bros. (sold through
www.*****************) arms on my '71 2wd blazer.
Nate Porter of Porterbuilt Street Rods (
www.porterbuiltstreetrods.com) will have is out by the end of the month.
Other sources are CPP, Performance On Line (POL), and Brothers Truck parts.
I guess the real question is,... what are you doing?
Stock, Static drop, or bags?
Post up pics of your truck when you get a chance,... and again welcome to the board. There is alot of info here!
