This is the Robinson Racing 60T GEN3 Slipper Unit for the Traxxas E-Revo Brushless Edition. It is a 0.8 module with a 60-Tooth Steel Spur/Slipper Pad/Backplate/Bearing assembly. Robinson Racing GEN3 Slipper Units can handle enormous the load conditions dispensed by today's high-power brushless motor systems. The new assemblies are a captured design to prevent slipper pad blowout and allow maximum power delivery to the ground. The high-performance hardened steel spur gear will not strip or fail. Both tough and strong, the 0.8 module/32-pitch teeth can handle all the power you can pour on the spur gear. And equally as tough, the aircraft grade billet aluminum backplate will not break or bend either. The increased surface area of the oversized slipper pad ensures consistent and dependable performance. The unit also benefits by its economy: less total parts reduces flex and wobble in the spur gear and slipper unit. The bearing shown is included as well.
