Two places to check, 1st make sure you have enough front end travel 5 to 6 inches, you may have to lower the front end to achieve this. 2nd make sure your rear shocks arent to short, because if they are as the chassis rises it will take the rear end with it and unload the tire causing it to bounce, resulting in poor 60ft times. Plenty of guys are using the same parts that you are, I think you just have some tuning to do good luck
