Changing gears to 4.88... rear locker or LSD... thoughts?

So I've been doing a little reading up on these mods and hear that when adding mods that increase the trucks overall weight, including up-sizing tires that a gear change will do wonders for getting the power back and get you back to the proper shift points. Has anyone gotten into this yet? Also, reading up on the LSD button for my 15 Tundra, as it's explained is more less just basically a soft traction control device and really won't 100% lock in when extreme demand is needed. Any truths to this that anyone can shed more light on...?

 

Seeing this may have just sold me on the lockers! https://www.youtube.com/watch?v=bvOgneVbVnE

 

ARB is a EXCELLENT set up ( there arb bumper on my tacoma has proved itself TWICE already) ...

im planning on doing it to my tacoma not my tundra. If it gets deep i will tell you like this the arb is not afraid to SNAP CV AXLES in half. There is a test on youtube showing how strong they really are. I was very impressed to say the least.

Problem with todays trucks is the ECM/transmission/ brakes/ABS ,,, all talk to each other now.. When it comes to extreme off-road when you would really use the ARB lockers it might come up short.. The arb is designed to give MAX torque to the wheels. Problem is simple with todays trucks the computer sees a wheel slip when its not, engaging the brake when in effect its HURTING what the locker is designed to do. Now you have a power struggle going on here not good when you need max torque.

If you could disable the units from talking so the brakes(abs) would apply during arb locking it would be ideal set up.

 

Thanks for your input @Mike @Sean266
