I have a 06' 2wd XE Titan and i am thinking about installing the cst 8inch suspension kit or a 6 inch fabtech kit.I have heard that there is a lot of vibration in the 2wd model after a lift kit is installed. I know that with a carrier bearing drop kit vibration is reduced, i was wondering if anyone already has either of these two setups and could give me some advice. I dont really do any off road driving i just want as close to factory ride as possible. I am planning to run 35x 13.50 inch tires on a 20 x10 inch rim with 4.5 inches of backspacing. Thanks.
