No that's not it. Trust me. My dad's street rod has firestone F7076 bags on the rear of it, they are the bags that come in a S10 air over leaf kit. They are rated at 800# at 100 psi, about half of an F9000, and about a third of a 2b6 or 255c. And when he had a blown 327 in it, it would launch with the front wheels up waist high. with 35- 45 psi in the bags. Now with a 300 hp crate motor, it still launches hard... only lifting one wheel a couple inches. It's not the bags that are your problem, it is the rest of the suspension. As you add air to the bags, you are lifting the truck, and changing the operating parameters of the fourlink.luvinitlow said:
maybe i jus got too much power for the softness of bags???
if i can decipher it correctly, i think what you're talking about is axle wrap. i've had 2 setups on my truck. the first was a lever setup. i got about 10-12" of lift out of it. i had the same problem though. if i was relatively low in the rear, i couldn't take off fast because the rear would slam into the ground. i took that setup off and went with a forward triangulated 4 link with over the axle bags. now i have no wheel hop or axle wrap. you really need a properly setup 4 link. thats what will solve everything.luvinitlow said:my buddy lever setup is too soft....he gets bout 14 inches of lift...unless he is pretty much all the way up,the ass end will drag...alot when at all low,when he accelerates from a lite and its a stock 4.3...i had my bags behind my axle b4 wit a modified gen 1 kit...haha...wit 2b6...and the only way id usually get it is if i had lotsa air in it...like 200 psi!!!
maybe i jus got too much power for the softness of bags??? i dont like the sounds of that....
