I bought a 2006 2wd Titan KC with a 15'' full throttle suspension lift and 3'' body lift with 40x15.50 toyos.
I recently bought some 49'' super swamper iroks to replace the 40s. after talking to some friends im concerned about my gear ratio and my axles, since i bought it already lifted im not sure if they were upgraded and if not should they be, to support the extra rotating mass that the 49s are gonna have?
I dont have a lot of knowledge with vehicles so any suggestions on what i can do to support the 49s is greatly appreciated!!!
If you already had 40's, and the guy put that much money into lift and tires, i wouldn't have a doubt in my mind he regeared it, most likely 4.56's, and with 49" tires, i would regear it, not a must, but i would recommend it imo.
