An oversized access hole and soft plug for easy access to the slipper clutch nut while still maintaining an unmatched seal of the gear mesh area. The plug stays in place yet is easy to remove and install.
Completely sealed. 
Stock gear covers have a large, open gap between the spur gear and the out-drive that allows gear destroying dirt to enter.
More clearance for larger pinions.
Retains all stock geometry for easy bolt up; no cutting or gluing required.
 Replaces stock Traxxas #3792. 
Does not include provisions for telemetry. 
Not recommended for spur gears larger than the stock 87 teeth.
