Fj60 rear locker id (1 Viewer)

[Arlo89]

Finally pulled my rear diff cover off to see what gears as I had because I couldn't tell by spinning the rear wheel and counting with the drives shaft. Too close to 4.56 or 4.88. Well I have 41 tooth ring and 9 pinion so according to Spicer it's a 4.56 gears. It also has a locker in it that I hate and don't need as I'll never need it. I currently run 33x10.5x15 and may eventually may put a h55f in it so would I be good to keep the 4.56 gears? Currently the speedo is 20 mph off at 55 so I have a digital gps and rpms are approx 2500 to 2600. If I hit 60 then it's damn near 3000. Advice? I've attached a picture of the locker

To me that looks like Aussie locker…

It’s a place to start. Contact powertrax or Aussie locker with those stamped numbers

Aussie locker or clone, works fine and with heavy trailer never an issue, bigger wheels has less clunck bang in corner and no airline, electrics or special maintenance needed.
If you want to remove them the original gear is to be found or find a replacement and make sure it is aligned properly.

You are correct. I scoured the internet and finally found pictures of their markings (the double diamond) on a jeep forum and it was it'd as a Richmond powertrax lock rite. Now to eventually get that out of there. This rig was wheeled before me, wont be anymore. Supposedly one of the previous owners put the 4.56 rear gears and locker in the rear and did not replace the front gears (yet to verify) so now I cannot use 4wd from what I've read. I just want a roadworthy rig.

I’m pulling my 3rds apart. If you were close I’d hand you a mint set of open spider gears. Should be easy to find wherever you are. If you are running 33” 4.11 with new H55 and that overdrive would be perfectly suitable.
