The TS-RK is a complete rebuild kit for the TS-2 truing st&. It is complete with the most commonly replaced small parts & the instructions needed to get your stand back into top working condition. In addition to making the stand more accurate & reliable, once installed, the new parts also allow the stand to be readjusted much more easily, should it be thrown out of adjustment. This is a great addition to the older TS-2 stands. If your stand has silver-colored shaft collars, upgrade with the TS-RK.
