I used 3" posies at the front and rear along with a 3" drop from Sid's Axles. For shocks, I called Posies, and they gave me the correct front and rear shock replacement model in order to work with the lowered springs and reduced travel. Came out pretty good. I have no idea how it compares to the original lever shock and springs, but it seems to ride pretty smooth and isn't the "horse buggy" some folks said it would be...
