Looking at the hpi savage steel bevel gears and aluminum cups. Those look like a good alternative for bulletproof spider gears. The cups take a 4 hole diff gear which is similar to losi lst.
Looking at the Losi lst ti plated diff and pinion. Those look like bulletproof diff option. With 4 hole diff gear.
