im trying to figure out if i really cant do a long arm lift without doing a t-case swap, i plan on doing one eventually but want to know if doing like a 4.5 long arm lift will cause the front driveshaft to vibrate in the awd transfer case? here in the summer i plan on doing a 242 swap to get rid of the 249 since for the most part they are plug and play (minus the input shat) anyone done a long arm lift on a stock 5.9?
