sky manufacturing sell a kit i think and so does all pro i wouldnt buy anything from trail gear... and def up grade your master with bigger breaks means more fluid volume so you need a way to hold more make sence? if you do the tundra up grade up front put the taco breaks in the rear and it will be perfect... unless you use like a gm monte carlo caliper and rotor setup in the rear you are going to need to purchase a transfercase mounted ebreak also from all pro ...hope this helps
