A 1" A-body bar is going to be stiffer than a 1" E-body bar because it's shorter.

I listed the older small bars on Craigslist and ended up selling them pretty quickly. So far I am impressed with the PST bars but they are keyed a bit differently and perfectly match the lowered spindles I bought from PST. I don't think their 1.03 bars have much (or any) pre-load from what I can tell. 8101050-DSC03443.jpg (52 downloads)

A 1" A-body bar is going to be stiffer than a 1" E-body bar because it's shorter. That would make sense that you'd have less leverage on a shorter bar & actually alot more of the rough ride than I attributed may have been from the Tbars. I got to thinking & blaming it on the SS springs (003 on both sides) since they raised the height up substantially (needed shock extensions) but it was a solid little A body 8101203-white65dodgedart004.jpg (38 downloads) live every 24 hour block of time like it's your last day on earth
