Updates:
I installed some 285-70-17 Falken Rocky Mountains ( exact same as the falken wild peak, but named different when purchased from Discount tire) tires and gave my maxxis big horn 315's to my brother. The maxxis tires looked great, but 11mpg for a daily driver was not cutting it. The new tires are much better and I am getting about 14mpg, with no tire howl and not wearing out the drive train as quickly.
Other than that, I have just been pondering my next modification. Drive rtain or suspension??
The truck is in need of a new engine and most likely a transmission. I have a spare LQ4 6.0 that i bought many years ago for a project, but i have been thinking of different transmission choices; Built 4L60E, a 4L80E or NV4500.
I am also considering a mid travel suspension kit that will swap out my torsion bars with a coil-over setup. JD Fabrication has a Mid Travel Upper a arm setup, and also has the other components avaliable to complete the swap.
