When designing a system that will work for what you want to do, you have to take several things into consideration. What size tires do you want to run, which the largest size you can run has to do with how strong your axles are and the gear ratios and all that engineering stuff. If you don't want to modify your axles, you can run a 31", maybe a 32 or 33. Also, do you want to be cuttin the fenders all up? I run a '99 with a 3" Pro comp with 31x10.50's, and it is a good lift, but I would go higher if I had to do it over again. Depending on who you talk to, you will get different answers on if you will need to do a SYE conversion with the 3" lift. It is a good idea to do it anyway, but that is the reason I went with the 3" so I wouldn't have the extra expense..... And have to do it anyway. So with a 3" lift, you have a 50/50 shot at the driveshaft conversion, anything over a 3" it is for sure. If I had it to do over.... I would go with the Roc krawer long arm kit. Wow! look at all these post since I started typing..... I need to learn to type quicker.... Ya! what they all said:laugh3:
