This is the Robinson Racing Gen3 Slipper Kit with 47-Tooth Steel Spur Gear for the HPI Savage X 4.6 trucks.
GEN3 Slipper Units will not fail under the enormous load conditions of today's high-performance engines. The new GEN3 Slipper Unit is a captured design to prevent slipper pad blowout and deliver maximum power to the ground. The hi-performance hardened steel spur gear will not fail or strip. Strong and tough 1.0 module spur gear can handle all the power you can pour on. Aircraft grade billet aluminum backplate will not bend or break. Increased surface area of the over-sized pad insures dependable performance. Less total parts reduces flex and wobble in the spur gear and slipper unit. Bearing is included.
