More Eaton | More Driveline and differential

Het Eaton Posi-differentieel met beperkte slip is de perfecte manier om de tractie in straat auto's, lichte pick-ups en asfalt raceauto's te regelen. Met pyrolytische koolstofkoppelingen, rebuildable ontwerp, gesmede tandwielen voor extra kracht en naadloze, automatische werking.

De positrac is niet het ultieme in dynamisch sper meganiek, maar aanzienlijk beter dan een open differentieel en precies wat een auto nodig heeft als deze al een hoop grip heeft.
