ProTaper 033281 Race Spec Aluminum Rear Sprocket Black 49T 428 Off-Road

The ProTaper 033281 Race Spec (RS) Aluminum Rear Sprocket delivers professional-grade drivetrain performance for off-road and motocross riding. Machined from premium 7075-T6 heat-treated billet aluminum, this 49-tooth, 428-pitch sprocket is engineered to the strictest tolerances for a precise, reliable fit.

At the heart of the Race Spec design is ProTaper's exclusive Angled Mud Groove — a self-cleaning feature machined into both sides of every tooth. This proprietary design actively sheds mud and debris during operation, preventing the buildup that causes horsepower loss and accelerated sprocket wear. The angled grooves also increase tooth surface area by up to 40% over competing sprockets, resulting in significantly improved chain contact and extended sprocket life.

Key Features:

• 7075-T6 heat-treated billet aluminum — the ultimate in lightweight strength for off-road use
• Exclusive Angled Mud Groove design on both sides of every tooth for continuous self-cleaning
• Up to 40% more tooth surface area over competing sprockets for improved chain engagement and longevity
• Precision CNC-machined to the strictest tolerances for consistent, reliable fitment
• Deep penetrating anodized finish for corrosion resistance and improved wear resistance
• Countersinks automatically center the sprocket to the hub during installation — no hub center guide needed
• Laser-etched tooth count for easy identification
• Engineer-designed lightening window pattern reduces unsprung rotating mass without sacrificing strength
• Made in the USA
