The Taiwan Factory Champion (TFC) Forged Aluminum Sheave is designed specifically for high-displacement GY6 150cc to 232cc builds where weight reduction and heat dissipation are critical. By replacing heavy stock cast-iron pulleys with CNC-machined forged aluminum, you significantly reduce rotational mass, resulting in snappier throttle response and higher peak RPMs. Technical Performance Features Rapid Acceleration: The lightweight forged construction allows your engine to reach its power band faster by reducing the parasitic drag on the drivetrain. Dual-Slot Tuning: Features user-selectable guide slots (Linear vs. Curved), allowing you to choose between a hard-hitting race launch or a smoother, linear top-speed transition. Superior Thermal Management: Aluminum dissipates heat far more efficiently than steel, protecting your drive belt from glazed edges and premature failure during high-speed runs. Premium Gold Finish: Features a high-quality gold anodized coating for superior corrosion resistance and a \"show-ready\" aesthetic. Comprehensive Fitment Guide This assembly is a direct-fit performance upgrade for 152QMI and 157QMJ based engines: Engine Codes Compatible Models GY6 150cc \/ 170cc Wolf, Icebear, TaoTao, ZNEN, Bintelli, Kymco GY6 232cc Custom B-Block Oil-Cooled Performance Builds Universal Fit Any QMJ, QMK, or QMI engine using a 28mm shaft Technical 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. Mechanic's Note: Rotational mass is the \"enemy\" of a fast-revving GY6. Tuning Tip: Use the Linear slots for drag racing and immediate take-off, or the Curved slots for a more consistent cruising RPM on the street. Installation Tip: This kit includes a high-grade Stainless Steel M28 Nut. Ensure you use a Clutch Holding Tool to torque it correctly to prevent CVT damage!
