Hey guys I'm having a bit of a problem with my truck launching few parts I just did are

What psi are you launching at

Unless there is a hard part issue what you are experiencing is torque steer. Lower the bars all the way down and that will help out. Getting the high offset wheels that are used on lifted trucks help create this problem. Running a wheel and tire that sits under the truck more will help with this problem.

If those are lift keys then even with them dropped you are not going to launch well

Yes, take the t bar bolts all the way out! The lift keys arent helping your cause, even when i took the t bar bolts out when i had lift keys it would still jump all over.. There are some guys here that race with lift keys but i dont think their 60 footers are as good as they could be if they were running stock keys.. U want to try and get ur cv axles as level as possible , thats 1 of the keys to getting a good smooth launch.u are fighting an uphill battle with those lift keys

remove keys and bolts, turn in right side bolt 2 full turns. attempt again at 10-15lbs with stock wheels and tires and it should do much better.

if your running blocks in the rear take them out, they cause axle wrap if you don't have traction bars. clamps obviously help as well
