Take your high-performance air-cooled engine to the next level with this precision-engineered Billet Crank Pulley by King Performance. Designed for serious builders, this pulley features a unique "frenched" design where the steel hub is recessed into the aluminum body for maximum stability, perfect concentricity, and a clean, high-end look.
Engineered for both traditional and modern EFI builds, the back of the pulley comes pre-tapped to work seamlessly with the Dub Shop Trigger Wheel, making it a true bolt-on solution for advanced ignition and fuel injection setups.
Engineering & Material Specs
Superior Hybrid Construction: The main pulley is CNC-machined from 6061-T6511 billet aluminum, mounted to a heat-treated 4340 chromoly steel hub with a durable black zinc finish.
Frenched Steel Hub: The hub is "frenched" into the pulley and secured with six stainless steel flat head cap screws for a rock-solid assembly that eliminates runout.
Hard-Anodized Protection: Finished in a .0015" thick hard-black anodizing for extreme wear resistance (note: like all anodizing, color may shift slightly over time).
EFI Ready: Features pre-tapped mounting holes designed specifically for the Dub Shop Trigger Wheel.
Precision Dimensions:6.7" (170.7mm) diameter for consistent performance.
