Actually they have one of the best steel gears and yes they will take aftermarket gears too. The folding stock i have runs a prometheus max torque peaks at 510 fps @ .2 the fixed stock runs all stock 420fps @.2 i have a third upper gearbox that shoots 350 too. You just need to adjust the motor height when you change gears and make sure they are properly shimmed.
