TPMS Service Kits for Gen 4

Would it be possible to get hold of TPMs service kits for the Gen 4 Jimny for the shop. I have had issues in the past with TPMs valve stems corroding and as they are now part of the MOT test I like to keep mine in good condition. I have had similar valve stems on other cars and have snapped banged and broken the valve stems. These I replaced with service parts from TPMS central. As a matter of course I replaced the stems whenever a tyre was removed or replaced and would like to do the same with the Jimny. The service kits tend to be less than a tenner the full tpms replacement is about £48
