I am considering changing my 4.10 R&Ps for 4.88. I am currently running 35s and my 700R4 tranny has an underdriven (.7 to 1) 4th gear. With the current set up I can do ~75 on the highway at about 2200 RPM. I will eventually go with larger tires, but want to know what I can expect to loose in top speed with the 4.88s. I would appreciate some comments from those of you with 4.88s and similar size tires.
What gears are preferred? Precision or Yukon, or ? Where should I purchase the gears?
