Thanks Matt. One more question if I may, how do you engage the lockers, and is i4WD still useable when not using the lockers?
Due to the way the locker is designed, when you engage 4wd, the locker will automatically engage. you will not have the option to use 4wd without the locker. Once the locker is installed, i4wd will not engage anymore and that is due to how i4wd and the locker works. With that said no modifications are needed to the i4wd system.
I'll explain why below if you want to know why, if not stop reading now since it will be kind of long. (I feel like all my post end up long, sorry haha)
Once you install the locker and you are in 2wd, the springs let the locker ratchet free allowing your front tires to rotate at different speeds as needed. This happens in 2wd because there is no torque/pressure being applied to the main pin of the locker.
Once your engage 4wd, there is torque/pressure on the main pin of the locker, and it can no longer ratchet free. All of this happens automatically through the mechanical design of the locker. None of locker is electrical or has anything to do with the i4wd system, it is 100% mechanical. All you have to do is engage or disengage 4wd with the button like normal, and the locker does it's thing.
No modifications are needed to the i4wd system. This is because the i4wd works off of speed sensors on either side of your front diff (You will be uplugging these wires from the wiring harness during install, to get the front diff out of the talon). When the computer senses one of the front axles spinning faster than the other while in 4wd, it electronically applies the brakes to that tire. That is the "i or intelligent" part of the system. Due to the locker always being engaged in 4wd, this means the front tires and axles will be spinning at the same speed no matter what. i4wd will never sense a speed difference and simply will never have to engage. So there is nothing you have to do with i4wd system. I left everything as is because the speed sensors are in the front diff and I didn't want to break the gasket or o ring seals on the sensors and plug the whole with something.
Torque Masters talks about this somewhere, maybe their website or FAQ's. I know I read something they put out on the i4wd system and the locker when I was doing my research before buying. They say there is no issues with leaving the i4wd system in place with the locker.
