f250 8000# stock pull??

Have a friend pulling this Wed @ Clermont County, Ohio with 2009, F250, 6.4L Auto. He does have a power adder box but I do not know which one. He has never pulled this truck, and has to remove a little weight to get down to 8000#. What gear?? Hi or low side of transfer case?? He thinks High side because he has more engine than his old 6.0L, I say low side.
Tire pressures f and rear,?? w/stock tires.
Any other advice?? TIA.

Depends on your hitch height, blow them up for whatever the tire is rated for.. You know all that weight transfer to the back.. I haven't pulled my '05 yet but from what I've seen the coil sprung front likes to hop... I'm working on a way to tie the front axle to the frame (pre-load) to keep from hopping and help hold the front down..

CowTruck, I will lower the front suspension (torsion bars) down onto the rubber bump stops. I do not have extra support for GM's weak tie rod ends and sleeves so drop the suspension to better the angles of the steering linkage.

My hitch height is 22" and max allowed is 26", I am going to borrow one if possible to get closer to 26".
thanks.....................

torsion bars? i thought this was a ford? it helps if you run a strap from the frame to the front of the radius arm and crank it down. like said, run max psi on the rear and run the fronts lower. mid 20s-mid 30s is good. 4lo and locked hubs for sure.

SSpeed,,,,, Sorry I confused this with another post elsewhere,,,,, yes this is a Ford, was asking for a friend. He pulled last night and went 272' with a very light 40hp tune and completely stock otherwise.
My Duramax took third, 10 inches less than second @ 273'.
