RPM's hottest selling molded gear covers are available for the Losi XXX & XXX-T! RPM gear covers are molded nylon, not vacuum-formed, which provides years of durability and protection and there is absolutely no drilling or cutting required. These gear covers are so strong that we guarantee that they will never break! RPM gear covers are molded in two more exciting and highly demanded colors — Yellow and Blue — as well as our ever-popular Black. All gear covers are sold with the necessary mounting hardware and RPM's trademark soft plug to seal out the dirt, dust, and debris from entering our large diameter, easy-access clipper clutch hole.
