I received a ton of e-mails regarding which track bar to use since NAPA cut the warranty on theirs from life to 100,000 miles. The hands down best I have used is from these guys: http://www.dtprofab.com/dodge.htm

It is rebuildable and uses a decent end on the frame mount that does not break loose like others. It is not cheap, but neither is your life.

 

Do you know if the Napa warranty is retroactive, in other words does the one I bought long ago assuming it had a lifetime warranty still have the lifetime warranty?
