geting ready to buy rims adapters and caps next week as well for tires, i have a few questions i would like to have answered if possible........
(i know the stealership very well)
im gunna do a 6" RCD lift with shocks with my rims/tires
stealer says they could flash computer or something to recalabrate for tire size but i would loose performance and mpg bc of 37" tires
so they said to do 4.56 gears and wouldnt have to recal. computer but would cost me $2,400 with full warrenty still, so should i just do everything without gears, or would gears be worth the POWER and MPG back?
im also gunna get mag tec diff cover and tranny pan with lift kit as well as s&B intake and Filter Back Exuast
thanks

If the money isn't a huge issue, do the gears too. You will notice a large power loss with the bigger rubber and stock gears. I notice it with only 33"s.

i got 33's on mine as well and notived a lil, just didnt know what 37's heavy a** tires on it would do, but money is a problem haha just want to do it right the first time
