I own a CUCV ex US-Army K30 Pick-up and I want to buy a 4" suspension lift kit. In my manuals about the CUCV they say it is a 1 1/4 Ton vehicle. I can't find a lift kit for a 1 1/4 Ton. What are the differences between a 3/4 Ton, 1 Ton and a 1 1/4 Ton lift kit. Are the front leafs different? Can I lift the rear with the shackle flip kit from Off-Road Design? Do I need to lower my T-case when I install a 4" lift-kit? Do you guys reccomment a specific lift-kit? I do a little off road.
