World Champion ACER Racing Ceramic Ball Bearing Kit for the HPI Racing Baja. We decided to set out to engineer the absolute best HPI Baja Bearing kit. We studied the car, the running conditions, the engine torque, the load placed on the bearings and engineered the perfect HPI Baja bearing in our World Champion Ceramic Nitride Pro Series material.
This is a full and complete 25 piece Baja Ceramic bearing kit. It includes the wheel bearings where we have created a perfect seal that keeps out dirt without compromising speed. It also includes all the transmission bearings and all the bearings in the entire car. We use a high strength high carbon chrome alloy HSR inner cage material, our diamond polished super smooth pure Ceramic Silicon Nitride Balls, and our special cream synthetic lubricant for friction free and cool performance.
