Actually increases it. It equalizes the rear traction because the bar won't allow the right rear to rise and lose traction, it will actually force it down better.
As for bars, Herb Adams said that he has never seen too large of a antisway bar. Hence his 1.5" rear.... The front isn't as big, but has short levers to make up for it. According to Jim Crocie at HO Racing, the front bar is 500-550 lbs/in deflection (I forget exactly, I'll dig up the email). So it is pretty strong, but I have a Rancho bar on my 80 T/A that will be coming off when I get some time that goes up to 900 lb/in with its adjustable lever 1.25" bar. Stiff in corners is an understatement, but I LOVED it. If you drive pot holes often, you may not like it.
I have a 64-72 A/G Body 1.5" bar I hope to get on mine soon too, but I won't till I put on the Rancho front (note it is an adjustable bar, so I can range it from 500 to 900 lb/in as needed). From what I have read, it looks like the 68-72 A/G LCA's will work on the 73-77 A/G cars and the 77-96 B/D cars were related to the 73-77's, so I am hoping it all works out.
Anyone know for sure??

Doesn't a large bar like the HO slightly decrease traction too?
