Review on Spicer 2016950 Differential Case Assembly by Robert Fulce

Let me start by saying that this is an exact replacement for the 2004 Nissan Titan with Electronic Locker. This is also an upgrade from the old 2 speed OEM locker as this locker is a 4 speed locker. The installation went without incident and so far everything (including the electronic locker) is working properly. The only reason I didn't give it 5 stars is because it's been in my truck for less than a month so durability is unconfirmed. This is definitely a cost-effective solution if you're having differential issues with an old Titan that came with an electronic locker.
