24 R Violent Bouncing On Launch

Does it do it in 2wd? If not its tire pressure and brake torque vectoring from software or like Nex said, travel issue from collars.

The shop told me to keep them at 48 for 5k miles. Not sure why. I'll drop them down and see how it goes. I appreciate your help.

That would make me nervous and makes absolutely no sense. Obviously that builder has never actually driven a Raptor, 48 is riding around on rocks. Can you call and ask him why? I run 32 cold tires, feel great at 35 warm.

you did too many changes in one time, so not easy to find the issue, first, low tire PSI and then you see.

Dropped the pressure to 35, didn't make a difference. I have it at a dealer operated performance shop running full diagnostics. I will update with their results.

Bummer I was hoping that would do it. On a side note I way looking at your pics of the shock buckets and was shocked to see the jagged cuts. So I went out and looked at mine and they are not as bad but still look like my son cut them with a sawsall. Definitely the worst cuts in factory parts I have seen. Why are they so bad, doesn’t look like that complicated of a part?

if you have your stock wheels and tires throw them back on and see if it changes anything

Put stock tires on and see what happens gets my vote.

Yea I run my 2020 F250 with Carli dominator and bags at 48-52 psi while towing at the 7500-10,000 lbs range! 32-35psi unloaded. Then up the psi from there for more weight.(38x13.50x18). 48 psi on the Raptor would be rough. All the suspension in the world will not smooth that out. Rubber bricks. Best start point is the tires. My 2 cents. But yea like the other comments. Too much at once. Makes the process of elimination very time consuming.

Try it in 4 high . 4A is using a clutch in transfercase to engage and disengage as needed. If clutch is slipping rear end may be over powering front axle. My Gen2 When i do boost launches or racing it , 4H only just no turning allowed . 4A if I'm playing or its raining and need to make turns .
