    First Name:
    2016 Tundra CREWMAX TRD 4x4
    Just a revtek 1.5" leveling kit on the front. I want to install airbags in the rear for towing my camping trailer. And I also want to find a nice ARB Locker Kit for the rear and if necessary I'll consider up front as well but not mandatory.
    So I'm trying to find the correct ARB Locker unit to install on my Tundra CREWMAX 4x4. I'm pretty green to all this stuff but after getting some insight from some guys on here, I'm having a little trouble finding the exact ARB unit for this model truck.

    I called ARB direct and they mentioned that for the front, the unit is an RD151 and for the rear it is an RD146, but I was also told to find out from Toyota what kind of factory FRONT AND REAR AXLE Shafts I have? What is the SPLINE COUNT? And what is the Diameter? Of what exactly, I don't know.

    After calling the Toyota Dealership where I bought mine exactly and speaking with a so called supervisor... I was asking for this info from a mechanical tech specialist and they said they don't provide that information. For me to call corporate. Kinda friggin stupid if you ask me. Corporate is gonna provide mechanical insight?

    Having said all this and wasting some of your time, can anyone provide me with those 3 specific things on my Tundra model so I can confirm it with ARB and order the correct parts prior to shipping?

    1. F & R axle shaft/s?
    2. " " spline count?
    3. " " diameter?

    Thank you kindly in advance.
