Fit my Dana 44, works like it's supposed to.
Needed this to go with my 4.88 gear change on my 2005 Jeep Wrangler LJ with the Dana 44 rear. Works great, no complaints, got yo play in the mud and snow. Was not disappointed.

Working very good.
This traction lock assembly is working nicely in my Firebird with over 400 RWHP and TQ. I did follow manufactures instructions as far as type of lubricate and break-in process. Unless you have all the tools and experience I recommend having a professional install this part.
