Super Diesel's sleeves and centerlink helped tremendously on the 2003 that we've been pulling. Before the truck would jump and bounce off the line. Now it's smooooth. You can see the truck in Schied's 2006 promo video (on their main site right now) drag racing in the far lane without the centerlink. On my site www.firepunk.com you can see the latest pulling video from Marysville.
sleeves work , and are cheaper than new Tie rods , however they are just a band aid for the real issue ,THE FACTORY RODS AND ENDS ARE WEAK ! LOOK INTO THE FABTECH !
