ProTaper 030027 Race Spec RS Aluminum Rear Sprocket 46T Black

The ProTaper 030027 Race Spec (RS) Aluminum Rear Sprocket is a premium, USA-made rear sprocket engineered for serious off-road and motocross competition. CNC machined from 7075-T6 heat-treated billet aluminum and finished with ProTaper's PTSE Hard Coat, this 46-tooth black sprocket delivers an elite combination of lightweight performance and exceptional durability.

At the heart of the RS sprocket is ProTaper's exclusive Angled Mud Groove technology, machined into both sides of every tooth. This self-cleaning design sheds mud during operation, preventing the dirt buildup that causes horsepower loss and accelerated sprocket wear. The precisely engineered groove layout increases tooth surface area by up to 40% over competing sprockets, dramatically improving chain-to-sprocket contact and extending overall service life.

Key Features:

• 7075-T6 heat-treated billet aluminum construction with PTSE Hard Coat finish
