New to the turbo diesel's. Bought my Dad's 2002 xlt lariet f250 extra cab. Came with 6 speed manual,7.3. Was wondering what you guys have been seen with the six speed as far as durability etc. My plans are air bags for the rear,controller,viair compressor and magnaflow 4 inch stainless exhaust. Also putting in a 2 inch leveling kit 315/75/16 BFG at's. Planning on running the egde with juice chip. Any thoughts or advice? Loads will be my 8.6 cabover with my 18 foot trailer with the cruiser/junk on it.
