Based on Alpha truck DOT testing, 916-267 still looks like a good sub mission. Pedal efforts are much lower than 916-46 except for the fourth 60 and 80 mph effectiveness tests. The reason for this, as you can see below, is that the pedal efforts drop dramatically for 916-46 after the fade' testing. In addition, the 916-267 material had shorter stopping distances of 20 to 40 feet during the 80 mph effectiveness test.'
