Horstman
AXS
Axle Clutch
The Horstman Roadrace Axle Clutch is without a doubt one of the best values ever developed in kart clutches since its introduction in 1984. Crafted from only the highest quality billet alloys for long life and consistent performance. Features cam action levers for quick acceleration. A special oil inside the housing is used to absorb heat from the friction discs to better control overheating. If a clutch overheats while engaging its torque capacity drops which means lost power and poor acceleration. Another benefit of a sealed oil bath design is that no outside contaminates can get inside to affect performance. Easy adjustment of stall speed can be made from outside the clutch. Model AX-4056 comes ready to race with any gear ratio from 4.20:1 up to 5.20:1. An optional tungsten weight kit is available to improve performance in the 5.20:1 up to 5.60:1 ratio range.
