Fitment and sourcing notes
Graders are precise machines — the wear items that stop production are circle drive teeth and wear strips, scarifier teeth, cutting edges, blade lift cylinder seal kits, king pins, tie rods and tandem bearings. These are the lines we keep moving fastest.
Give us the model, serial number and either the part number or a photo; we will confirm stock, grade and freight to your site.
