Re: Which would be better???
Running a 4.16-1 t-case will counteract the 30" tires perfectly, and you can get it done for $450.
Putting in 5.12 R+P will put your final drive way high and your engine will turn 4800 rpms at 60mph, My thought is overreving, but then again my 86 has a 4.16 t-case and 5.12 R+P.
I would have to say do the t-case first, this way you will have the 4.16-1 low and this would be better off road than the 5.12 R+P with the 2.26 factory low. You will also not lose anything on road due to the t-case high range will perfectly match the tires you plan on using.
