I was looking over my 5th wheel and I noticed I could see the bolt hole in one of the hangers. So after some looking on the Internet I found this kit from Dexter Axle(K71-449-00 Heavy Duty Suspension Kit for 1 3/4 leaf springs) . It replaces the bolts with ones that you can grease, the equalizer which you also grease, the hangers are twice as thick, and the plastic bushings with bronze ones. Installation was straight foreword so I won't bother you guys with that but here are some pictures.
