Introducing our Super Lightweight 100% Duralumin Pulley Set, a cutting-edge marvel crafted from a specialized alloy of aluminum (comprising over 90%), copper (around 4%), magnesium (0.5%-1%), and manganese (less than 1%). Before undergoing a meticulous final heat treatment, this alloy exhibits remarkable ductility and malleability. Post-treatment, a synergistic reaction between aluminum and magnesium significantly enhances hardness and tensile strength.

Primarily designed for the aviation industry, our pulley set utilizes this Duralumin alloy in both the pulley’s outer and inner plate components, ensuring an exceptionally lightweight body. The material’s innate properties make it an ideal choice for drag racing cars surpassing 1000 horsepower and 10,000 RPM, thanks to its super-high durability achieved through a hard almite coating.

What sets our product apart is its exclusive design tailored for individual IN and EX pulleys. The adjustment part of both pulleys reaches its zenith precisely at the engine’s TDC, facilitating seamless valve timing adjustments. The pulley and inner plate, meticulously curved from Duralumin, boast extreme high precision, particularly in the pulley gear, ensuring a flawless transfer of drive from the timing belt.

Our commitment to excellence extends to the aesthetic realm. The pulley, crafted from Duralumin and adorned with a hard almite coating, not only performs exceptionally but also enhances the overall look of your engine room. The color of the pulley serves as a visual testament to the strength of the hard almite coating.

Navigating adjustments becomes effortless with our simple adjustment scale, strategically applied to accommodate unexpected arrangement changes. The sliding type and Duralumin gear material further contribute to the precision and longevity of our pulley set.

This Super Lightweight Duralumin Pulley Set, weighing a mere 497g each, is meticulously tailored for Mitsubishi Lancer Evolution models (IV to VII) with 4G63 engines. Elevate your driving experience with our state-of-the-art pulley set, where innovation meets precision seamlessly.
