TFC Forged Aluminum Sheave Assembly - GY6 150cc-232cc

Upgrade your CVT system with the ultimate in precision engineering. The Taiwan Factory Champion (TFC) Forged Aluminum Sheave is designed for high-displacement GY6 150cc to 232cc builds where weight reduction and heat dissipation are critical. By replacing your heavy stock cast-iron pulleys with forged aluminum, you significantly reduce rotational mass for snappier throttle response and higher peak RPMs. 

Performance Benefits:

• Rapid Acceleration: The lightweight forged aluminum construction allows the engine to reach its power band faster by reducing the energy needed to spin the drivetrain.

• Customizable Tuning: Features user-selectable guide slots (linear vs. curved), allowing you to choose between a hard-hitting launch or a smoother, higher top-speed transition.  

• Superior Cooling: Aluminum dissipates heat far more efficiently than steel, protecting your belt from glazed edges and premature failure during high-speed runs.

Specifications:

• Material: Forged Aluminum with a Gold Anodized finish
• Rear Pulley Plate: OD: 141.84mm / Shaft ID: 28mm / OD: 40-45mm / H: 77mm
• Secondary Slider Plate: OD: 141.84mm / Funnel ID: 34mm / OD: 43mm / H: 47mm
• Metal Secondary Spring Seat/Funnel: ID: 43.3mm / OD: 45mm / H: 37.20mm
• Included Hardware: Stainless Steel M28 Clutch Nut, 3 Steel Slider Pins/Guides, and pre-installed O-rings.
