I put a set in an LJ Rubicon for Darren ( formerly known as goblazers_6) , the gears were fine but I didnt care for thier install kits. They didnt seem to have enough different shims to make the combination I needed, lucky for me I have a bunch of leftover shim sets at the shop so it wasnt an issue.
Also IIRC they supplied Koyo bearings rather then Timken bearings.
But for the money they seemed like a good deal, he has been driving and wheeling with them for about a year now with no issues.
