Mac 12mm 12 point impact, snap-on pin retaining impact u-joint and 6 inch pinned impact extention. It's all dedicated so it never comes apart. I do alot of 8.8 Mustang rears so it gets quite the workout
Some you have to use a wrench and I have encountered this.Ford put the heads of the bolt towards the transfer case housing which a socket will not into.I use a 12mm Mac and Proto 12 point socket on a 6 inch extension.Problem with Sunex is getting them replaced under warranty.Had one impact swivel break and took monthes to get a replacement.
