Introducing our Super Lightweight 100% Duralumin Pulley Set – the epitome of cutting-edge engineering for high-performance vehicles. Crafted from a specialized alloy of aluminum (comprising over 90%), copper (around 4%), magnesium (0.5%-1%), and manganese (less than 1%), our Duralumin pulleys offer unparalleled strength and durability. The alloy’s ductility and malleability are harnessed through a meticulous heat treatment process, resulting in heightened hardness and tensile strength.

In the realm of aviation, Duralumin stands out for its remarkable lightness and exceptional physical properties, making it a staple in the aircraft industry. Our pulley set leverages this material’s advantages, serving as the ideal choice for both the pulley’s outer and inner plate components, thereby achieving a super-lightweight body.

Enhanced durability is a hallmark of our design philosophy. By applying a resilient hard almite coating to the pulley’s surface, we have elevated its overall lifespan significantly. This robustness makes our pulley set suitable even for drag racing cars with power exceeding 1000 horsepower and reaching speeds of 10,000 RPM.

Precision is at the core of our design. The individualized approach to the IN and EX pulleys ensures that the adjustment part peaks precisely when the engine is at Top Dead Center (TDC), facilitating seamless valve timing adjustments. Our pulley and inner plate, crafted with extreme precision from Duralumin, guarantee an efficient transfer of drive from the timing belt.

Functionality meets aesthetics in our design. The choice of Duralumin as the primary material, coupled with the sleek almite coating, not only enhances performance but also contributes to an attractive appearance in the engine room. The color of the pulley reflects the strength of the hard almite coating, symbolizing both form and function.

To cater to real-world usage scenarios, we’ve incorporated a straightforward adjustment scale. This simplifies the adjustment process, enabling quick responses to unexpected arrangement changes. Our Sliding-type gear, made from high-quality steel, complements the Duralumin pulley, resulting in a harmonious combination of strength and precision.

This pulley set is tailored for Nissan enthusiasts, specifically designed to suit the Nissan 180SX S13 – SR20DET, Nissan Silvia S13 – SR20DET, Nissan 200SX S14 – SR20DET, and Nissan Silvia S15 – SR20DET models. Elevate your vehicle’s performance with our Super Lightweight Duralumin Pulley Set ? where innovation meets reliability in perfect harmony.
