2 x rubberised rockers with 2 x grease nipples on each rocker – rubberised because both ends of the springs are fixed therefore jarring would occur if rocker was not rubberised – there would be no give.
8 x brass bushes (these bushes go inside the eyes on each leaf spring)
8 x shackle plates ½” thick (these are double the thickness therefore our bolts are longer) (the standard ½ U-bolt thread – electric brake system)
Provides a buffer between a 5th wheel hitch and kingpin
Easily fits on any standard kingpin
Reduces normal wear and tear when towing
Eliminates messy grease deposits on hitch plate
Constructed from tough polyethylene
