UPDATE.....GOT TRACTION !!!! Since starting this thread in 2005, I made a change that did more for my traction than anything else I have tried (air bags, no-nops, 70-30 front shocks). I have new MOOG soft springs on front and rear!! Yes, I removed the no-hops, air bag, 70-30 shocks and the big fat stock GS springs. Now I get STREET BITE like I never thought possible! Try these MOOG springs. (CORRECTION previous numbers removed) 5230 Front and 6321 rear I prefer Moogs over Morosos which start slowly falling ...wheel alighnment changes monthly till the bumper drags the ground. NO... Moogs last forever. Morosos last a year or two, maybe. I now have: Cheap gas shocks ft and rr. 7/8 stock rear GM swaybar UMI adjustable upper arms Edelbrock lower arms (prefer Curries) Pinion angle set 2 degrees down (tweaked upper right arm 1/4 turn tighter for a straight shot off the line and tiny preload to stop twist and plant the right tire. If I sell my Switch Pitch, & get a JW 9.5" 3700 converter, I W I L L have traction problems again! Q. WHAT WILL GARY DO THEN? A. GET AN HR BAR. No further experimenting needed.
