I haven't changed to a different equalizer, but I can tell you that the cables are very susceptible to rust and not allowing the cable to move. The second area of concern is how they routed the cable along the frame. I can't speak for the STD cab, but on my ECSB I made a modification to the final bracket before the cable turns up and meets the equalizer.
In the factory manual, you are supposed to use a drill bit to secure the pedal at a certain height(stick your head under dash and look for a hole to appear on the geared pedal bracket as you engage the pedal) and then adjust the equalizer as needed. The problem is that the self-adjusters on both drum brakes need to be set first before adjusting the equalizer.
I'm probably not doing a very good job explaining this. A picture would be better.
Here is one of my bracket mod using a Patio Door bearing and some clamps. I dont have a welder at this time, but I might have someone help me construct one better. But this does work, and my Parking brake pedal is super smooth now.
