I'm finally getting my lift installed after saving for it most of last year. It seems like it's one expensive after another but I know that's the life of a Jeep Owner. Anyway, I'm excited to see my Jeep finished and was telling someone who is a little familiar with Jeeps about my setup and the Mopar Stage 3, 3'' lift I'm installing in my 2dr and the 35s im putting on in my JK and he said I'm gonna need to replace my drive shafts. Is there any reason my drive shafts need to be replaced with thus lift and 35s? . And if so how much time do I have with the stock drive shafts?
