Upgrade your Volkswagen MK8 GTI with the NEUSPEED Power Pulley Kit, engineered to reduce parasitic drivetrain loss, improve throttle response, and free up additional horsepower.
Designed specifically for the EA888 Gen 4 turbocharged engine found in the 2022+ Volkswagen MK8 and MK8.5 GTI, the NEUSPEED Power Pulley Kit replaces the heavy factory crankshaft pulley with a lightweight 7075 aluminum underdrive pulley. By reducing rotating mass and accessory drag, the engine revs more freely while improving throttle response and overall driving performance.
Quick Fitment Overview
- Compatible with Volkswagen MK8/MK8.5 GTI (2022+)
- 20% underdrive crankshaft pulley kit
- Includes crankshaft pulley, crankshaft bolt, and drive belt
Product Description
The NEUSPEED Power Pulley Kit is designed to reduce parasitic power loss caused by the factory accessory drive system. By underdriving the alternator and air conditioning compressor, less engine power is consumed by rotating accessories, allowing more power to reach the wheels.
The lightweight crankshaft pulley is CNC-machined from premium 7075 aluminum and weighs just 13 oz compared to the factory pulley's 64 oz. This significant reduction in rotating mass helps the engine rev quicker while improving throttle response and engine acceleration.
For long-term durability, the pulley features a hard-anodized finish along with NEUSPEED's exclusive heat-treated stainless steel wear ring that prevents premature wear against the front crankshaft oil seal. The complete kit includes a new crankshaft pulley, replacement crankshaft bolt, and correctly sized serpentine belt for a true bolt-on installation.
Best For: Drivers looking to improve throttle response, reduce rotating mass, and gain additional horsepower on the Volkswagen MK8 GTI.
