Gear Ratio and Brake Job?

[Zed 71]

I am surprised you did not notice a deterioration in braking performance with those larger and heavier tire/wheel setup. When my truck was fully stock, I thought the brakes were terrible. The stock setup is very prone to fade and does not do well with heavy loads.

I changed my rotors/pads at 20k and driving through the mountians it makes a big difference. When I installed the much heavier tires, I did not notice any change in braking performance. One of the best mods IMO.

As far as warranty, look up the Magnuson (spelling?) Act.

You might as well just go thru with the gear swap...your drivetrain warranty is questionable since you installed the lift. The dealer would have to prove that the aftermarket item caused whatever issue you took it in for, look up the Magnuson/Moss Act read and understand it as most dealers have no clue about it.
