Serpent have released this improved gear-diff for use in the S411. The main improvements are the new gears with improved shape, which run smoother, combined with coated aluminium 3.5mm shafts. The case has also been updated but the super light spring-steel adapters remain as before. Supplied complete with shims, high quality hardware and o-rings. The V2 gear differential is standard in the 411-TE kits and can be used both front and rear in the 411.
