ProTaper 033395 Race Spec Aluminum Rear Sprocket Orange Sprockets - 40T

The ProTaper 033395 Race Spec (RS) Rear Sprocket is a precision-engineered, 40-tooth aluminum rear sprocket finished in anodized orange. Built for off-road and motocross riders who demand reliability and performance, this sprocket is crafted from 7075-T6 heat-treated billet aluminum and precision CNC-machined to the strictest tolerances.

At the heart of this sprocket is ProTaper's exclusive Angled Mud Groove design, incorporated on both sides of every tooth. This innovative feature creates a self-cleaning effect during operation, continuously shedding mud and debris that would otherwise cause power loss and accelerated sprocket wear. The precisely machined groove geometry also increases tooth surface area by up to 40% compared to conventional sprockets, resulting in significantly improved chain contact and extended sprocket life.

Installation is simplified by built-in countersinks that automatically center the sprocket to the hub — no hub center guide required. A deep-penetrating anodized finish provides long-lasting corrosion resistance and improved wear resistance, while laser-etched tooth count markings make identification quick and easy.
