I hear you&#39;re supposed to adjust the bars for street driving and re-adjust them again at the track to snub the traction bar against the spring.

I&#39;ll let you know how mine do when I install them this is why I purchased them (&#036;325.00) since there&#39;s nothing better besides a 4-link. I twisted the u-bolts out of the rear end with all of the wheel hop going on off the line. I spent this weekend with the daughter since it was here birthdayso maybe next weekend will be free for me.

your going to see about 2/10&#39;s with the 4.10&#39;s over the 3.73 stewbie, good luck on your quest.

that would make me more than happy. i was really just hoping to improve my 60&#39; a little. i figured 1/10 going from 3.73&#39;s to 4.10&#39;s. detroit tru-trac goes in soon too. then the last thing on the to-do list is the transmission and ill be golden. actually 243 heads might accidently slip in there before the transmission lol. cant pass up freebies&#33;
