Hello I have a stock 03 ford x with 7.3 diesel. I'm looking to make a few modifications to make it a better tow vehicle..... can you please advise me on what are the things you would suggest? I have a budget of about $1500-2000 or do you think just buying a arrow Hensley is my best bet? I'm having sway issues pulling a 7000lb trailer. I was thinking exchanging front leafsprings and adding a rear helwig sway bar..... for starters. What is your advice? If you recommend leaf spring swap what codes for front and what for rear (if that's needed?) also I will be putting new shocks all the way around. Thanks and I'm in the Houston area....do you know of a shop in town to help me? I've called several ford dealerships and they act like they don't understand/can't do leaf spring swap.....?//
