I am going to regear and am trying to decide between 4.56 and 4.10.
I have an Auto with 31's now but will be getting 32s this summer, actually 265/75-16s which are between 32/11.50s and 33/12.50s . I am only going to regear once and would like to pick up some power. I drive the vehicle 2-3 hrs to wheel sometimes and take one or two 5+ hour trips a year do you think 4.56's would be too much on the h-way.
I am leaning to the 4.56's for the better offroad ability, and from whay Ive been told the new cam in my engine has shifted the power band up 300-400rpm. The 4.10s would put the rpms about 5% higher(~100rpm) than my stock gear/tire combo-3.55's. I figured that the engine would be turning 2300rpms at 65mph with the 4.56 and 32s with OD. Is this true in the real world? I turn 2000 at 70 with 235s.
If 4.30s were avail for the front Id get them but the jump is to 4.56 so...
Sorry to ramble, Im just looking for some opinions.
Thanks
