Power Pulley Kit • 2.8L 24V Mk4 Golf/Jetta

Your car's power steering pump, alternator, and air conditioning compressor are driven by a belt connected directly to the crankshaft pulley. Spinning these heavy factory accessories draws precious horsepower away from your engine. To reclaim this lost performance, NEUSPEED's powertrain engineers utilized sophisticated CAD software to perform a precise mass properties analysis, resulting in this highly optimized Power Pulley Kit. By installing these perfectly balanced under-drive pulleys, you effectively reduce parasitic drag on the engine, allowing it to rev faster and deliver noticeably more power to the front wheels.

Precision-machined from premium billet 6061-T6 aluminum, NEUSPEED Power Pulleys are built for an exceptionally long service life. Unlike standard cosmetic color anodizing, these pulleys undergo a specialized hard-anodizing process that builds a resilient, wear-resistant hardened layer over the base aluminum, ensuring maximum durability and protection against belt friction over time.

Features

• Increased Horsepower: Effectively reduces parasitic drag on the engine's accessory belt system to unleash a proven 5 to 7 horsepower gain.
• Lightweight Construction: CNC-machined from aerospace-grade 6061-T6 billet aluminum for a significant reduction in rotational mass compared to heavy factory steel pulleys.
• Hard-Anodized Finish: Treated with a specialized hard-anodized coating that provides exceptional surface hardness, preventing premature belt wear and long-term material degradation.
• Comprehensive Kit: Includes precision-engineered under-drive pulleys for both the crankshaft and the power steering pump, along with a brand-new crankshaft pulley bolt for a secure and proper installation.

Notes

• Performance Gains: Yields an estimated 5–7 horsepower increase.
• Vehicle Fitment: Engineered exclusively for Volkswagen models equipped with the 2.8L 24V VR6 engine.
• Visual Accuracy: The product photos showcase the actual precision-machined pulleys and exact hardware configuration included in the package.
• Origin: Proudly designed, engineered, and manufactured at our R&D facility in Camarillo, California, USA.
