Upgrade your XRAY XB2 Buggy with this Schelle Racing Nova Slipper Clutch! All parts necessary for the conversion are included, including the Nova XB2 Aluminum Topshaft, XB2 spacer tube, and 5x13mm topshaft bearing.

The Nova Slipper Clutch is the ultimate 3-plate clutch that has better driving feel, lasts longer, and has a lower rotating inertia. Weight is 12.0 grams for the entire Nova Slipper Clutch assembly using the included 81 tooth spur gear.

Schelle Chief Engineer Kurt Wenger created a 3-plate design which solves all of the problems racers are having with kit slipper clutches that degrade and lock-up. In addition, it is smaller and weighs less making it the ideal slipper clutch for stock racers. The Nova Slipper Clutch has 20% more torque capacity in a compact package that helps you put more power to the ground and lasts longer between rebuilds. The other benefit of the Nova over other brands is that Nova sets include 2 slipper pads of each material we offer and a tuning guide to help racers learn how to tune the clutch for different conditions from slick to astro-turf.
