Xceed NT1 & 733 composite gear diff gear sets
Xceed have composite gear differential gear sets for Xray NT1 and Serpent 733 1/10th scale gas cars. The precision molded composite gears, combined with light alu shafts, create a lighter and super smooth working gear-differential. The NT1 set needs just the gears and shafts, while the 733 also needs the light steel adapters and small bronze bushings to complete it. For both cars the alu shafts are a direct replacement for the original ones.
