I purchased this kit for an Arcan trolley jack as I have a newly painted floor that I didn’t want to be damaged by my current metal wheels. This kit is great and of very high quality, the caster wheels were a straight swap but the main front wheels have an internal diameter of 18mm where I needed 20mm. I must stress that this is because I am using the kit on a different jack than it’s designed for, and the issue was easily over come by machining out the excess material.
If the exact specs of the kit (thread sizes, wheel size inc internal and external diameters) where available more of these kits could be used by other Jack users wishing to carry out a conversion.
Good value top quality but unfortunately they did not fit my Jack even after checking with technical and being told they would do a little disappointing
