Hey guys. I have an 09 HSE. As you probably guessed, it does not have the differential locking feature. My next question is what does it take in order to swap the E locker, what do i need aside from the actual diff? I bought the truck to use it so it will be used for some pretty intense road trips and travels, a locker out back would be nice. Anyone who has any information, it would be greatly appreciated. Thanks!
