Positraction rearend Burnout

[johnpaulgolf]

I got all happy about my fuel leak fix so I did a burnout for the first time in my dually.

Come to find out ALL four smoked down

Is this a factory thing they do for all dually's or did I get lucky and buy one that is locked?

I dontk now, but I bet there was a hell of a lot of smoke and I guarantee you whoever is looking at that burnout now is scratching their head thinking "what the hell is this"

Dually burnout are cool to see. Makes you take a second look. Dually doughnuts are cool too.

Could be two things. Ford did put Limited Slip in most 4x4's. It can transfer up to 15% of the unused torque from a slipping tire to the non slipping tire when you happen to be slipping. It helps, but it is not as good as a real locker.

The other thing is that you had equal traction on both sides, so neither one is going to be able to slip more than the other.

I have done dually burnouts on several trucks, and they always seem to light both sides. With my '08 F350 running spartan tunes, I can pretty much burn out for a city block. It always burns both sides. By the time the ground speed catches up to the speedometer speed, you are doing about 70mph. The first time I did that, my rear end started making noise right afterward, and i just knew that I had ripped the limited slip clutches. I changed the fluid and put in Royal Purple synthetic, and it quieted back down.

Sounds like a really good way to snap an axle shaft.

Yeah it was super duper badass fo sho

I have also noticed in the past that when I turn real sharp it acts like a posi ... especially when backing up ... at first I thought it might be just a dually thing nut now I think I do have a posi or a locker or maybe spooled or maybe welded and and and and and and and and and adn
