I built a Baja 5b ss and it is a beast! with the modifications i have done to the engine, i am getting almost 4hp out of it and 12k rpm. The diff was simple to build and works very well. They make one with a plastic case and a alloy case, get the alloy case. When i first saw the thread this is the diff i was going to reccomend and then saw someone else already had done so.
