Ok I've been thinking about what to upgrade next. I have a 6 inch Rough Country lift with Spacers and I don't know whether to re-gear first or upgrade to Coilovers and upgraded shocks out back. What do ya'll think? Also, which gears should I go with? I know Yukon or G2, but 4.56 or 4.88? I have a 2008 Supercrew 4x4 with 18 inch rims and 35 inch tires.

Thanks
