What is your objective?
Are you wanting to get bigger tires? How big?
Search f150 coil spacers for the front, $60 at dealer, $20 at junkyard. Get 1.5 inches of lift, takes an hour to do. You will need an alignment after, so add that to the cost.
Warn 153 shackles for the rear. $70 on ebay (est) takes an hour to install yourself.
$200, and your lifted enough for 31" mudders! Now go wheeling and enjoy your rig like you never have before!
