These drive sprockets drive off of four track lugs and track clips at once with just one pair of drive wheels. They increase performance by eliminating both rotating mass and track ratcheting. For use on tracks with all windows open. This is the most efficient and durable drive sprocket on the market today. 

Slide rail modification and installation of anti-stab wheel kit required on some models. 

Sold per each.
