Very little use

Threaded rod extensions 5/8"-18, lengths "3-1/2", 6", 12" you can extend legs 3" at a time or put them together with coupling nuts. Good for pulling bearing off of axles or shafts. You can also use 1 of  the 3-1/2" extensions and coupling nuts for adaptor for 5/8-18" slide hammer attachments.

I would only recommend long extensions for pulling with bearing splitter.

The OEM tools bearing splitter is the same as an OTC 951 or 1123
