    I've searched, unable to find anything.

    Anyone have insight into whether or not someone is working on a front locker? Preferably air...

    Got one installed today. You want the RD-121.

    Now I'm puzzled, he has exactly the same truck I do. Mine was installed at Mule Expedition, whose techs are former ARB employees (ARB is based nearby in the US). The receipt they gave me has it as an RD-121.

    I know if you plan on also going to 4.88 you want to go with the RD-121 since I guess you can't find R&P's for the RD-111. But I didn't tell them I was going to re-gear. I'll call them in the morning and find out.

    Don’t be confused. I don’t know what ratio his truck has and I wasn’t going to take more time to look it up cause he didn’t try very hard.
    It clearly shows on the link I posted that 3.73 and down is
    $1,091 RD121 Air Locking Differential
    RD121 and 3.91 and up is RD111.

    Yeah, but mine's an auto (3.909), so it should be a RD-111. His would be different if he has a manual, same if an auto. I need to find out what they actually put in there. I'd be really surprised if they messed that up. They have a great rep afaik.

    Mine is AT as well. Somehow I missed that the 2005 and "on" part. Everything else is typically 2015 and on or 2016+ so when I was skimming through and would see 2005 at the beginning I just assumed it was a gen 2 part. Thanks for the help!

    So the answer is they don't know why the receipt says RD-121. It was from when I put down a deposit a couple months ago. The user/parts manual they gave me was for the RD-111 and they confirmed that is what they put in.
