Any Gearheads on here?
Been looking at used trucks, Silverados or Sierras mostly. Been debating between 3.42 and 3.73 rear ends. I understand better milage with the 3.42, better towing and torque with the 3.73. Leaning toward the 3.73, but there are a lot more of the others available. Then there's 6-speed vs. 4 speed. So I'm wondering, does the 6 speed offset the 3.42 in terms of towing performance so it will not suffer compared to a 4 speed with the 3.73 gearing?
