Reedy Serrated Cavity Motor Brush

The Reedy Serrated Cavity Brush is a laydown-style motor brush featuring a single vertical cut design that increases contact with the commutator for more punch and improved throttle response compared to a standard stock brush. This serrated cavity design is intended primarily for stock motor applications, giving stock-class racers a noticeable performance boost without the added complexity of a full modified motor setup. As with other serrated performance brushes, the increased commutator contact does mean more frequent maintenance and inspection are needed to keep the motor running at its best, so it's worth checking brush wear regularly if you're running this upgrade. Genuine Reedy motor brushes are manufactured to consistent quality and dimensional standards, ensuring proper seating and reliable electrical contact inside the motor can for dependable power delivery. This brush is a simple, affordable way for stock-class racers to extract a little extra punch and responsiveness from their motor without swapping to a full modified system. Sold individually as a genuine Reedy replacement motor brush, and a worthwhile addition to any stock racer's spares box.
