Lighter oil will make traction rolling worse.
I would try lowering ride height first, then stiffer sway bars, then stiffer springs and thicker oil. Reducing negative camber can also be a quick help.
Thanks for the tips DTR, I will try some of these things first. I think it might just be that I need to adjust my driving style as this truck is so much more settled than the old one. I used to rely on the little bounce the old truck made after landing to kick the rear out for the next corner in a few spots. The new truck is much more planted so doesn't do the bounce..the rear just bites hard and over she goes.
