ProTaper 033401 Race Spec Rear Sprocket 46T Orange Aluminum 428 Chain

The ProTaper Race Spec (RS) Rear Sprocket represents the pinnacle of off-road drivetrain technology, engineered for serious motocross and off-road riders who demand maximum performance and durability. This 46-tooth sprocket features ProTaper's revolutionary Angled Mud Groove design that creates a self-cleaning effect during operation, preventing dirt buildup that leads to horsepower loss and accelerated wear.

Key Features:

• Constructed from heat-treated 7075-T6 billet aluminum for exceptional strength-to-weight ratio
• Precision CNC-machined to the strictest tolerances for perfect chain alignment
• Exclusive mud-groove design on both sides of every tooth increases surface area up to 40% over competing sprockets
• Deep penetrating orange anodized finish protects against corrosion and improves wear resistance
• Countersinks automatically center sprocket to hub during installation—no hub center guide needed
• Designed for 428 chain size
• Made in USA

The proprietary angled groove pattern is CNC machined in the opposite direction of load-bearing teeth, creating the largest possible tooth surface area for optimal chain contact. This innovative design significantly increases sprocket life while reducing unsprung rotating mass for improved suspension performance and acceleration.
