i haven't regeared mine yet either, when i bought my lift i bought:
-6" Procomp Lift
-Longer Stanless Steel Brake Lines up front
-(4) 35" Procomp Xtreme Mud Terrains
-(4) Dick Cepek DC1 16x10 rims
-Full set of spline drive lugs
-Install on all the above
-Set of Chrome Gibson Headers
-AEM Brute Force Cold Air Intake
-New Pitman and Idler Arms w/ Install
and after the hour drive home..... new calipers and pads since they couldn't bleed the old calipers... talk about a FUN truck to drive without brakes....
all of the above set me back around $3500. i took the truck to the shop, 4-5 days later picked it up with the lift/wheels/tires/idler& pitman arms on it and the other parts and stock tires/wheels. in the back
the regear on mine to take it to 4.56 or 4.88's with install fees ($300+ and axle) came out to an estimated $1200 give or take a little. the gears alone were around $450 i want to say. need to dig out that estimate i have and take a look at it.
i plan on doing the gears myself to save that $600. (the $600 should pay for all the specialty tooks to redo it, and i'll be able to change any others from now on out. i like being able to do it all myself)
